The question whether the art of making moulds
and casts in plaster was known to the ancient
Greeks and Romans was discussed some years ago
by Mr. Charles C. Perkins, in an interesting pamphlet
entitled “Du Moulage en Plâtre chez les
Anciens,”8 in which he collected various passages
from ancient writers bearing more or less on this
subject, and endeavored by their authority to establish
the fact that this process was known and
practiced at a comparatively early period in the
history of art. After a careful examination of
all his citations and arguments, as well as other
authorities which he does not cite, we feel compelled
to dissent entirely from his conclusions.
We do not think he has made out his case. The
question is an interesting one, however, from an
archæological point of view at least, and well deserves
consideration.
The only passage among the writings of the
ancients which at first sight would seem directly
to affirm that the process of casting in plaster
from life, from clay models, or from statues in the
round, in the modern meaning of that phrase, was
known to the Greeks and Romans occurs in the
“Natural History” of Pliny, and is as follows:—
“Hominis autem imaginem gypso e facie ipsa primus
omnium expressit, ceraque in eam formam gypsi infusa
emendare instituit Lysistratus Sicyonis, frater Lysippi,
de quo diximus. Hic et similitudinem reddere instituit,
ante eum quam pulcherrimum facere studebant. Idem
et de signis effigiem exprimere invenit, crevitque res in
tantum, ut nulla signa statuæve sine argilla fierent. Quo
apparet antiquiorem hanc fuisse scientiam quam fundendi
æris. Plastæ laudatissimi fuere Damophilus et Gorgasus
idemque pictores qui Cereris ædem Romæ ad Circum
Maximum utroque genere artis suæ excoluerunt.”9
Mr. Perkins, following in substance other translators,
thus freely translates and develops this
passage:—
“Lysistrate de Sicyone fut le premier à prendre en
plâtre des moules de la figure humaine. Dans ces
moules il coulait de la cire, puis il corrigeait ces masques
de cire d’après la nature. De la sorte, il atteignit
la ressemblance, tandis qu’avant lui on ne s’appliquait
qu’à faire de belles têtes. Lysistrate imagina aussi de
reproduire l’image des statues, procédé qui obtint une
telle vogue, que depuis lors ni figure ni statue ne fut
faite sans argile, et l’on soit en conclure que ce procédé
est antérieur à la fonte du bronze.”
If this translation be correct, there seems to be
no doubt either that Pliny was mistaken, or that
the ancients knew and practiced the modern art
of casting in plaster.
Is, then, this translation correct? It seems to
us to be an utter misapprehension of the whole
meaning of the passage. Pliny says nothing about
moulding or casting, and thus to translate and
amplify the words he does use is to assume the
very facts in question. What he really says is literally
as follows:—
“Lysistratus of Sicyon, brother of Lysippus, of whom
we have spoken, first of all expressed the image of a
man in gypsum from the whole person [that is, made
full-length portraits], and improved it with wax [or
color, for, as we shall see, cera means both] spread over
the form. He first began to make likenesses, whereas
before him the study was to make persons as beautiful
as possible. He also invented expressing effigies from
statues; and this practice so grew that no statues or
signa [which were full-length figures either painted,
modeled, cast in bronze, or executed in marble] were
made without white clay. From which it would seem
that this science [or process] was older than that of casting
in bronze. The most famous modelers were Damophilus
and Gorgasus, who were also painters, and who
decorated the temple of Ceres at Rome with both
branches of their art.”
The first sentence, thus literally rendered, it
will be perceived, has in many respects the same
ambiguity in English as in Latin. The words
“image,” “expression,” and “form” have all a
double signification, and the question is what is
their true meaning in this connection.
If it can be shown that this passage neither
describes nor proposes to describe the process of
casting in plaster, as we understand that phrase,
the keystone of the whole argument that it was
known to the ancients falls out. No other writer
directly asserts that such a knowledge or practice
existed, and all allusions to this matter contained
in any ancient author are purely collateral, and
have no force in themselves. Further, some well-known
facts which we shall have occasion to bring
forward later are entirely opposed to the probability
of such a knowledge and practice.
It is upon this passage in Pliny, then, that the
whole case depends. Now, in a doubtful and obscure
question like this, dependent upon the statement
of any single author, we have a right to
claim three things: first, that the statement should
be clear and fairly susceptible of only one explanation;
second, that it should not be contradicted
by a subsequent statement immediately following;
third, that the author himself should be trustworthy.
And in the first place, as to the author. The
“Natural History” of Pliny is certainly a most
interesting, amusing, and in many respects valuable
book, but quite as certainly it is one of the
most inaccurate that ever was written, abounding
in half-knowledge, second-hand information, legendary
statements, and rubbish of every kind. It
is, in a word, the commonplace book of an agreeable,
gossiping man, of a wide reading, who took
little pains to be accurate, who reported everything
he heard with slight examination, who was
exceedingly credulous, and who accepted as truth
and fact the most ridiculous stories. All is fish
that comes to his net. In his chapters relating
to artists and art he is singularly devoid of judgment
or accurate knowledge; he constantly confuses
things which have no relation to each other,
often contradicts himself, and becomes at times
utterly unintelligible. Yet we are forced to turn
to Pliny, to give a weight and authority to his
words upon art, and to own a deep debt of gratitude
to him, not because he is trustworthy, but
simply because he alone of all the ancient authors,
with the exception of Pausanias, has given
us a detailed account of the statues and artists
of antiquity. His account of the ancient artists
and their works is the fullest we have, and adrift
as we often are on a wide sea of conjecture, we
are glad to seize upon any straws and fragments,
“rari nantes in gurgite vasto” of blankness
and doubt; seizing here a bit from Pausanias,
Herodotus, or Lucian, there a waif from
Cicero, or a floating fragment from one of the
great tragic poets, and glad enough to get upon
any such raft as that which Pliny gives us, however
leaky and rickety. But seaworthy or trustworthy
in emergencies Pliny certainly is not.
In the next place, as to the passage under discussion.
So far from its being clear and distinct,
its obscurity, confusion, and apparent contradiction
are so great as to have baffled every effort to
explain it satisfactorily; and Dr. Brunn, one of
the most accomplished of archæologists, in his
history of Greek art, finding it impossible to reconcile
the different sentences, does not hesitate to
treat a portion as an interpolation, or at least out
of place where it appears.
Two views are to be taken of the process described
by Pliny: first, that by the term “cera”
he means wax; and second, that he means color.
Taking the first view, let us now consider the passage
in question, sentence by sentence, and endeavor
to unravel its real meaning. Lysistratus,
first of all, made likenesses of men in gypsum from
their whole figure (that is, whole-length portraits),
and improved them with wax (or color) spread
over the form (core or model) of gypsum. “Imaginem
gypso e facie ipsa expressit” are the words
of Pliny which Mr. Perkins in common with other
translators supposes to mean “made moulds in
plaster from the face,”—“prendre en plâtre des
moules.” But this simple phrase cannot be
twisted into such a meaning. “Exprimere,” according
to Forcellinus, is “effingere, rappresentare,
assomigliare, ritrarre dal vivo.” “Exprimere”
alone would be, therefore, according to this last
definition, to make a portrait from life. The additional
words, “imaginem e facie ipsa,” make
this meaning still stronger. “Imaginem” means
a full-length figure or likeness, and not a mould,
as would be required by Mr. Perkins’s translation.
“Exprimere imaginem” cannot be forced to mean
“made a mould,” whether in gypsum or in any
other material. Suppose we translate the words
literally, “to express an image in plaster,” and interpret
“image” to mean mould, it is plain that
the phrase is wrong; it should be impress and not
express. You cannot express a mould. It is impressed
on the face. In like manner when Plautus
says “expressa imago in cera,” or “expressa
simulacra ex auro,” he means making a portrait in
color or in gold. Again, “facies” does not mean
face, but the total outward shape, appearance, or
figure of a man. “Vultus” is the proper term
for face, and is so used by Pliny himself; as when
he speaks, for instance, of the portraits of the
head of Epicurus as “vultus Epicuri,” and distinguishes
them from the full-length figures of
athletes, “imagines athletarum,” with which the
ancients adorned their palæstra and anointing-rooms.
In fact, the whole chapter in which this
passage occurs relates to portraits, and is entitled
“honos imaginum.” If there could be any question
on this point, it would be settled by a passage
in Aulus Gellius (13, 29), in which he defines
“facies” as the build of the whole body,—“facies
est factura quædam totius corporis;” and
Cicero, in his treatise “De Legibus” (1, 9), says,
“That which is called ‘vultus’ exists in no living
being except man,”—“Is qui appellatur vultus
nullo in animante esse præter hominem potest.”10
So Virgil in “vivos ducent de marmore vultus”
means the face. “Imago,” on the contrary, and
“facies” mean the whole figure; only “facies”
means the real figure, and “imago” the imitation
of it. Pliny himself invariably uses them so,
and in one of his letters (ep. 7, 33, 2) he recommends
that we should be careful to select the best
artist to make a full-length likeness,—“Esse nobis
curæ solet ut facies nostra ab optimo quoque
artifice exprimatur.” By the word “exprimatur”
he certainly does not refer to casting. So mechanical
an operation as this surely does not require
the best of artists. “Imaginem e facie ipsa”
means therefore a full-length likeness.
Again, “infundere” does not necessarily mean
pour in, but is quite as often used in the sense of
poured over or spread on; as where Ovid says,
“infundere ceram tabellis;” or where Virgil says,
“campi fusi in omnem partem,” or “sole infuso
terris;” or again where Ovid uses the phrases
“collo infusa mariti” or “nudos humeris infusa
capillos,” it can only mean spread over. Wax
cannot be poured into a flat surface like a tablet,
or hair poured into shoulders.
Mr. Perkins, with Forcellinus before his eyes,
after citing his definitions of “exprimere” says:
“Explications qui toutes rentrent dans l’idée de
représenter, de reproduire, de prendre sur le vif,
comme on dit en français, et par conséquent dans
l’idée du moulage.” But “ritrarre dal vivo”
means nothing more than to make a portrait from
life, whatever “prendre sur le vif” may mean; nor
can any one of Forcellinus’s definitions be tortured
into an allusion to casting. “Mais,” he continues,
“cette idée surtout est accusée dans Tacite, qui dit
en parlant d’un vêtement que dessinait les formes,
un vêtement collant ‘vestis artus exprimens.’”
But surely this phrase means simply a garment
expressing, or as we should say showing, the limbs,
and has nothing more to do with “casting” than
“dessinait les formes” has to do with drawing,
or a “vêtement collant” has to do with glue. He
also thinks another phrase used by Pliny—“expressi
cera vultus”—has a similar significance.
If all our metaphors are to be subjected to this
strict test, we must be very careful how we speak.
Yet these and similar examples, which he says he
could multiply, “peuvent suffire,” he thinks, “pour
nous autoriser à croire que Pline a voulu dire que
Lysistrate était l’inventeur de la reproduction des
statues par le plâtre, en d’autres termes qu’il était
le premier qui avait eu l’idée de se servir du gypse
pour mouler.” This, to say the least, is going
very far. With such philologic views, what would
he think of this phrase, “vera paterni oris effigies,”
or “vivos ducent de marmore vultus,” or “infans
omnibus membris expressa”? Or, to take an
English line, what would he make of—
“The express form and image of the King”?
But if Pliny meant casting, why did he not use
the appropriate Latin word for that process—“fundere”?
In the subsequent sentence, speaking
of casting in brass, he says “fundendi æris.”
“Fundere” meant to cast, not “exprimere.”
Besides, let us look at the practical difficulty in
this process. After the moulds were made and
the wax cast into them, as Mr. Perkins interprets
Pliny to mean, we have still only wax impressions,
and not plaster castings. And how were they got
out of the mould after they were cast? We, in
modern times, have learned no method of doing
this; we should be obliged first to make the
mould in plaster, then to make a cast in plaster in
that mould, then on that cast to make a piece-mould
with sections to take apart,—an elaborate
process; and then we could get a wax cast, but
not before. The fact that the cast mentioned by
Pliny (supposing he means a cast) is in wax not
only involves quadruple labor and skill on the
part of the caster, but makes the process impossible,
or next to impossible, if it were simply as he
is supposed to describe it. If the cast were in
plaster, it would resist, so that the mould could be
broken off from it in bits; but with wax this
would be entirely impracticable.
Let us still further consider the phrase “ceraque
in eam formam gypsi infusa emendare instituit.”
What does “cera in eam formam infusa” mean?
Simply to cover or spread wax (or color) over
that model; just as Ovid says “infundere ceram
tabellis,” to spread wax over the tablets, not to
pour wax into the tablets, for that was impossible,
they being flat surfaces, nor to cast them. Again,
Pliny does not say that Lysistratus introduced the
practice of spreading wax over a core, or of pouring
wax into a form, or casting; but only of improving
the likenesses, or working them up in the
wax after it was spread over the plaster: “instituit
emendare,” he says, not “instituit infundere.”
“Formam” here has not the signification of mould,
but of model or image. Undoubtedly the term
“forma” in Latin was used to signify a mould as
well as a cast, or a model, or a form; and in this
respect it had the same ambiguity that the corresponding
terms “mould” and “form” have in
English. A “form” is a seat, as well as a shape
and a ceremony, and “mould” is constantly,
though improperly, used to indicate a model or
the thing moulded, as well as the real mould in
which it is cast; the phrases “to model” and “to
mould” are often synonymous in meaning. So
“forma” was sometimes employed in its primary
significance of figure, shape, and configuration, as
when Quinctilian says, “Eadem cera aliæ atque
aliæ formæ duci solent,”—various shapes may
be given to the same wax; sometimes in the sense
of image, as when Cicero speaks of “formæ clarissimorum,”
the images of distinguished men; sometimes
to mean a model or shape over which a thing
is wrought, as a shoemaker’s last,—“Si scalpra
et formas non sutor emat,” as Horace says; and
sometimes as indicating a hollow mould in which
bronze is cast, as when Pliny says, “Ex iis [silicibus]
formæ fiunt, in quibus æra funduntur,”—from
these pebbles moulds are made, in which
brass is cast. But when he uses it in this last
sense, it will be observed, Pliny employs the term
“fundere,” to cast, and not “exprimere,” nor
“emendare.” In the passage about Lysistratus,
then, “forma” would seem to mean a model, or
core, like the shoemaker’s last, on which the wax
was spread for the purpose of emending or improving
something. What is that something which
Pliny tells us he improved by this means? What
can it be except the “imaginem,” the likeness?
There is no other word to which “emendare” can
refer. If, then, we understand the passage as meaning
that Lysistratus modeled a likeness in gypsum,
and then improved it or finished it in wax which
he spread over the gypsum, the statement is quite
intelligible, and not a word is warped from its correct
significance. If we adopt the other interpretation,
however, we must understand “imaginem
gypso expressit” to mean that he made a mould
in gypsum, contrary to the direct force of the
words; and with wax poured into that mould
(making “formam” equivalent to “imaginem,”
and referring to it) he emended or improved—something.
What? Why, the mould,—which
is absurd. Again, we cannot begin by making
“imaginem” mean the cast, before the “formam”
or mould is made; not only because the practical
process is thus reversed, but because then we
should have a cast in plaster made by pouring
wax into the mould, which is even more absurd.
Taking “forma” to have in this sentence any of
its meanings except “mould,” we have no difficulty
in understanding it; taking it as “mould,” we
are forced to change the primary significance of
“imaginem” and “expressit,” and are involved in
very serious questions.
In addition to these considerations, it must not
be forgotten that this cast of gypsum, according to
Mr. Perkins’s interpretation of the sentence, was
made not of the face alone (“vultus”) which is
by no means an easy process, but of the whole figure
(“facie”), which is a very hazardous one, and
to which, with all the knowledge and experience
of the present day in casting, few people would
be willing to submit.
A passage of Alcimus Avitus, in his poem “De
Origine Mundi” (lib. 1, 6, 75), throws a clear
light on the process which seems here to be described
as the invention of Lysistratus:—
“Hæc ait, et fragilem dignatus tangere terram
Temperat humentem conspersa pulvere limum
Molliturque novum dives sapientia corpus
Non aliter quam opifex diuturno exercitus usu.
Flectere laxatas per cuncta sequacia ceras
Et vultus complere rudes aut corpora gypso
Fingere vel segni speciem componere massa
Sic Pater Omnipotens.”
Here we have the body modeled (“fingere” is
to model) in gypsum, and the ductile “cera”
spread over all the undulations, and the rude face
finished, just as Pliny describes it.
Let us now consider the next sentence, in which
he says, “Hic et similitudinem reddere instituit,
ante eum quam pulcherrimum facere studebant.”
This certainly has nothing to do with casting. It
is very important as throwing a reflex light on the
previous sentence. The whole stress of the passage
is to bring out the fact that Lysistratus made
portraits. He used a peculiar process, perhaps,
but his specialty was that he made portraits from
life (“imaginem hominis e facie ipsa”), which he
worked up in wax (“emendare cera”); and not
only this, but his portraits were exact likenesses
(“similitudinem reddere instituit”), and not merely
ideal figures like those of the artists who preceded
him (“ante eum quam pulcherrimum facere studebant”).
A slight glimpse at the history of the art will
clear up this matter. In the early period of sculpture,
only statues of divinities were made, and up
to a comparatively late time these archaic figures
were copied for religious and superstitious reasons,
and the old formal hieratic type was strictly observed.
It was not until the 58th Olympiad that
iconic statues began to be made in honor of the
victors in the national games, and these for the
greater part were rather portraits of the peculiarities
of general physical developments than of the
face. Portrait statues of distinguished men now
began to be made, but they were very few in
number, and only exceptionally allowed by the
state. The first iconic statues, representing Harmodius
and Aristogeiton, were made in 509 B. C.
by Antenor. Phidias followed (480 to 432 B. C.),
and during his period the grand style was in its
culmination, and for the most part divinities or
demigods only were thought worthy subjects for
a great sculptor. Iconic statues were, however,
executed during this period, and among the legendary
heroes and divinities who formed the subjects
of the thirteen statues erected at Delphi
and executed by Phidias out of the Persian spoils,
the portrait of Miltiades was allowed,11 but the
erection of public portrait statues was very rarely
permitted, and the introduction by Phidias of his
own portrait and that of Pericles among the combatants
wrought upon the shield of his ivory and
gold statue of Athena occasioned a prosecution
against him for impiety. It is said that Phidias,
in his statue of a youth binding his hair with a
fillet, made the portrait of Pantarces, an Elean
who was enamored of the great sculptor, and who
obtained the victory at the Olympian games in the
86th Olympiad (B. C. 435). But this story, which
is given by Pausanias, rests, even by his own
account, purely on tradition, and was apparently
founded upon a supposed resemblance between
Pantarces and the statue. Portraiture in its true
sense, however, now began, and soon after the
death of Phidias, about the 90th Olympiad, Demetrius
obtained celebrity as a portrait sculptor.
He seems to have been the first to introduce the
realistic school of portraiture, copying so carefully
from life, particularly in his likenesses of old
persons, that he was reproved for being too faithful
to Nature. Quinctilian accuses him of being
“nimius in veritate” (xii. 10); Lucian in his
“Philopseudes” calls him an ἀνθρωποποιός, and,
describing a statue by him of Pelichus the Corinthian,
says it was αὐτῷ ἀνθρώπῳ ὁμοῖον,—like the
very man himself. Callimachus, also, at the same
period obtained the nickname of Κατατηξίτεχνος, on
account of the extreme detail and finish of his
works. These artists flourished nearly a century
before Lysistratus; and Pliny therefore is incorrect
in his sweeping statement that before the
time of Lysistratus sculptors had only endeavored to
make their statues as beautiful as possible, and
not to give accurate portraits. Still, these men
must be considered as exceptions to the general
practice, and it was not until the time of Alexander
that portrait-sculpture in the sense of accurate
likeness was developed. Up to that period it still
was heroic, generalized, and ideal in its character,
with comparatively little individuality or detail.
The portrait statues, for instance, of the Royal
Family by Leochares (372 B. C.), and that of
Mausolus (about 350 B. C.) on the famous Mausoleum
erected by Artemisia, were treated in this
style. Lysippus, however, during the reign of
Alexander of Macedon, by his great talent gave a
new impulse and development to the school of portraiture,
and while retaining the heroic character
he gave a more realistic truth to his works. Pliny
speaks of him as distinguished for the finish of his
work in the remotest details,—“argutiæ operum
custoditæ in minimis rebus.” In his portraits of
Alexander he represented even the defects of his
royal patron, such as the stoop of his head sideways.
Such was his skill that Alexander declared
“that none but Apelles should represent him in
color, and none but Lysippus in marble.” Lysistratus
was the brother of Lysippus, and Pliny says
that he introduced the practice of making portraits
which were not merely heroic and ideal likenesses,
but faithful representations of the real men. In
attributing to Lysistratus the introduction of this
practice of individual portraiture, Pliny undoubtedly
goes beyond the real facts. He did not
introduce the practice, he merely developed it by
a peculiar process, giving additional verisimilitude
thereby. This process was roughly modeling the
likeness in plaster, and then finishing the surface
and the details in the “cera” with which he covered
it.
In painting, the sphere of portraiture was larger
than in sculpture, and subject apparently to no
such restrictions. The earliest portrait on record
by any great painter was not of hero, philosopher,
or athlete, but of Elpinice, the daughter of
Miltiades and the mistress of Polygnotus, who
painted her portrait as Laodice, one of the daughters
of Priam, in his famous picture representing
the “Rape of Cassandra,” in the Pœcile at Athens.
This picture was executed about 463 B. C., when
Elpinice must have been at least thirty-five years
of age. Dionysius of Colophon was also a distinguished
portrait-painter and celebrated for his excessive
finish. Nicephorus Chumnus, the grammarian,
describes Apelles and Lysippus as making
and painting Ζῶσας εἰκώνας καὶ πνοῆς μόνης καὶ κινήσεως
ἀπολειπόμενας,—being likenesses only wanting
breath and motion. For one of his portraits of
Alexander Apelles received twenty talents of gold
(£5,000), which was measured, not counted, out
to him. He also painted the portraits of Campaspe
and Phryne in the character of Venus, taking
the face from Campaspe and the nude figure
from Phryne. Speaking of Apelles, Pliny himself
relates in his thirty-sixth book that “he painted
portraits so exact to the life that one of those
persons called Metoscopi, who divine events from
the features of men, was enabled, on examining
his portraits, to foretell the hour of the death of
the person represented.” And this monstrous story
Pliny apparently accepts. At all events, he does
not question it. Parrhasius, “the most insolent
and arrogant of artists,” says Pliny, “painted a
portrait of himself and dedicated it in a public
temple to Mercury; and though the Athenians
had publicly proceeded against Phidias for so
doing, they allowed it to Parrhasius, thus plainly
showing that the dignity of sculpture was higher
than that of painting.”
But to return from this digression to the consideration
of the passage by Pliny relating to portraiture
in modeling and sculpture. In the sentence
immediately following, Pliny goes on to say,
“Idem et de signis effigiem exprimere invenit, crevitque
res in tantum, ut nulla signa statuæve sine
argilla fierent,”—Lysistratus also made copies
from statues, and this practice came so into vogue
that no statues in brass or marble were made without
white clay. What the meaning of this sentence
is we can only guess; as it stands, it is quite
unintelligible. Perhaps he intended to say that
Lysistratus set the fashion of making small copies
in clay or terra cotta of all the statues that were
executed. But it is quite possible that he meant
nothing of the kind. It is plain that if Lysistratus
had already invented casting in plaster, it would
have been unnecessary to copy statues in clay, except
for the purpose of reduction to statuettes.
Mr. Perkins thinks he may have intended to speak
of “esquisses d’argile [maquettes] dont se servent
les sculpteurs comme point de départ, esquisse reproduite
plus tard en marbre et avec la mise aux
points.” But there was nothing new in this; and
surely Lysistratus could not be said to have invented,
or set the fashion of, a process which certainly
had been employed very long before his
time. And again, why make a small statue in clay
and enlarge it proportionally in marble, if you can
make it at once in full size and cast it? Nor does
Mr. Perkins seem to be aware that in adopting
this view, and translating as he does “de signis
effigiem exprimere,”—to make a small model or
maquette in clay,—he abandons his explanation
of the sentence referring to gypsum. For if
“effigiem argilla exprimere” means, as he says, to
make a model in clay, why does not “imaginem
gypso exprimere” mean to make a model in plaster?
Besides, the fact that Pliny applies the same
terms to a process in clay as to one in plaster at
once puts an end to the matter so far as the question
of casting goes. Clay is not a material to
cast with, in any proper sense of that term.
Another objection to this interpretation that
Pliny meant a maquette, “esquisse,” or sketch is
that “effigies” did not mean sketch. It carried
with it nearly the significance of our own word
effigy,—of great reality of imitation. “Imago”
was a vaguer word, and might indicate a delusive
resemblance as by painting; but “effigiem”
was ordinarily employed to designate a more absolute
imitation. Thus Cicero says, “Nos vere
juris germanæ justitiæ que solidam et expressam
effigiem nullam tenemus. Umbra et imaginibus
utimur.”12 And again, “Consectatur nullam eminentem
effigiem virtutis sed adumbratam imaginem
gloriæ.” “Effigies” would, therefore, carry no
such idea as that of sketch.
Besides, not only is “effigies” not the correct
word for sketch, but Pliny would scarcely have
used it in this sense, when immediately afterwards,
speaking of the sketches of Arcesilaus,
which sold for more than the finished works of
other artists, he employs the appropriate term for
sketches,—“proplasma.” In the translation of
Pliny, published by Mr. Bohn, and made by Mr.
Bostick and Mr. Riley, this term is translated
“models in plaster;” but it simply means sketches
or antijicta, in whatever material they were made.
The words “plastæ” and “plasma” have nothing
to do with plaster. “Plastæ” were simply modelers,
and πλαστική was the art of modeling,—the
plastic art.
Again, Pliny could scarcely have intended to
say that Lysistratus invented modeling sketches
of statues in clay before executing them in plaster,
since he tells us explicitly that Pasiteles used
to say that plastice was the mother of statuaria,
scalptura, et cælatura; and, though he was distinguished
as first in all these arts, he never executed
anything in them until he had first modeled
it in clay,—“nihil unquam fecit, antequam
finxit.”
Before leaving this sentence, let us take a different
view of its possible meaning. May not Pliny
use the words “signa” and “signis” to mean pictures
and not statues? Undoubtedly “signum”
was thus used, as where Plautus speaks of a “signum
pictum in parieti,”—a picture painted on the
wall; or where Virgil speaks of a “pallam signis
auroque rigentem,”—a mantle stiff with embroidered
figures and gold. In this sense the passage
would mean that Lysistratus made effigies from
pictures as well as from statues, and that thenceforward
not only no statues but no pictures were
made without being copied in bas-relief, or in the
round, argilla, or white clay. This would account
for the use of the word “effigiem,” which has a
stronger significance of reality than “imaginem.”
The succeeding sentence is even more obscure;
and, unless it be interpolated or out of its proper
place, is quite unintelligible. In the connection in
which it now stands it is absurd. It is as follows:
“Quo apparet antiquiorem hanc fuisse scientiam
quam fundendi æris,”—by which it seems that this
knowledge or practice was older than that of casting
in bronze. What is the “scientiam” to which
he refers? He has previously spoken only of two:
first, that of making portraits in plaster and wax;
second, that of making copies of statues in clay,—both,
as he says, invented or introduced into practice
by Lysistratus. But to say that that artist
could have invented any process older than that of
casting in bronze is not only ridiculous in itself,
but inconsistent with what he has previously told
us; since at least two centuries previous to the
time of Lysistratus, Rhœcus and Theodorus of
Samos—as we learn from Pausanias, Herodotus,
and even Pliny himself—exercised the art of
casting in bronze. Pausanias,13 indeed, tells us
that these sculptors invented this art; but Pliny,
with his usual inaccuracy and carelessness, says
that they invented “plastice,” or the art of modeling
(“In Samo primos omnium plasticen invenisse
Rhœcum et Theodorum,” ch. xxxv.),—an
art which from the very nature of things must
have been practiced from the earliest and rudest
ages, almost from the time when the first child
made the first mud-pie.
Dr. Brunn,14 in commenting on this passage in
Pliny, accepts the first sentence as describing the
art of casting in plaster, but, finding it impossible
to reconcile it with the subsequent sentences,
ingeniously suggests that it was an addition inserted
in the margin, and afterwards interpolated
into the text by the copyists in the wrong place.
Throwing out this first sentence about Lysistratus
from this place, he still accepts it, and interprets
it to mean that Lysistratus invented the art of
casting. The subsequent sentences he connects
with a previous passage in Pliny, in which he
gives an account of Dibutades of Sicyon, a potter
by trade, and relates the legend that this artist
drew the outline of the face of a girl whom he
loved from her shadow on the wall, and his father
pressed clay upon it within those outlines, and
made a typum which he baked. The passage, according
to Dr. Brunn, then would continue: “He
[Dibutades] also invented the making of effigies
from signa, and this practice so increased that
thenceforward no statues or signa were made
without argilla; so that it appears that this art
was more ancient than that of casting in bronze.”
By accepting this suggestion of Dr. Brunn we certainly
relieve Pliny of the absurdity of stating
that any “scientiam” or practice invented by
Lysistratus was older than casting in bronze, since
centuries before his time bronze figures of colossal
proportions had been cast. But even supposing
these sentences to refer to Dibutades and not to
Lysistratus, they are far from being clear or accurate.
Is it possible to believe that, while the
making of brick and earthenware utensils and
fictile vases is so ancient that the memory of man
runneth not to the contrary, no one before Dibutades
had ever attempted to model a figure or a face
in clay, or to put a model into a furnace and bake
it? All history is against such a supposition.
Images in terra cotta were made by the ancient
Egyptians, Babylonians, and Ephesians centuries
before Dibutades. The ancient Etruscan terra
cottas previous to his epoch were scattered, as
Pliny himself says, all over the world: “Signa
Tuscanica per terras dispersa.” The capitol was
decorated with earthen statues at the time of the
first Tarquin, and Pausanias mentions many clay
statues of gods and demigods executed in the earliest
ages of Greece itself.
Again, from this very passage it is clear that
Pliny himself admits that there were signa and
statuæ already existing at the time of Dibutades,
of which he first made effigies. What did Dibutades
invent? Certainly not the art of modeling
in clay, or of baking the clay. His statement,
also, that thenceforward no statues were made
without clay is scarcely intelligible, unless we
suppose him to mean that clay models were made
thenceforward before executing statues in stone or
other materials. But he does not say this. Again,
he cannot mean that Dibutades first invented
taking impressions from indented outlines, or intaglii,
for this was as old as the first primitive
seal, and was no more invented by Dibutades than
by Lysistratus.
Dr. Brunn interprets the statement in respect
to Dibutades as showing that he was probably the
first inventor of casting, at the same time that he
also interprets the sentences referring to Lysistratus
as declaring that he first invented casting,—the
only difference being that the process of the
one was in clay, and that of the other in plaster.
But is it clear that Dibutades, according to
Pliny, ever made even a stamp in clay from indented
outlines on the wall? The passage is ordinarily
so interpreted, but is this interpretation
correct? Pliny says that Dibutades having traced
the shadow on the wall in outline, his father impressed
clay within that outline, and thus made a
typum which he baked with other articles of earth,
and which was long afterwards preserved in the
Nymphæum at Corinth. His words are, “quibus
lineis pater ejus impressa argilla typum fecit.”
What, then, is the meaning of “typum”? Evidently
not a mould, or impression, but a relief.
Had it been a mould, he could have stamped from
it a hundred impressions, since it would have been
merely a seal with an irregularly relieved outline;
and in order to have the repetition of what was on
the wall he must perforce have stamped from it
an impression. This he evidently did not do, or
at least nothing is said to indicate anything of
the kind. He preserved and baked what he first
obtained, which, if it was merely a mould, would
have produced, to say the least, no effect. The
true as well as the literal translation of this passage
would seem to be, “within the outlines by
putting on clay he made a relief.” This clay he
probably modeled as well as he could, keeping
within the lines, and then removed it from the
wall and baked it. The same interpretation of
this passage is given by Giovanni Battista Adriani,
in a remarkable essay or rather letter addressed
by him to Giorgio Vasari in 1567, in which he
gives a summary of the most celebrated Greek artists
and their works. “Typus” in Latin had the
double significance of “intaglio” and “relievo,”
as our word “type” has of the type itself and the
printed impression; and sometimes it was used
in one sense and sometimes in the other, but it
was usually employed to mean a relief. Thus
Cicero, in one of his letters to Atticus (lib. i. ep.
10), writes, “Præterea typos tibi mando quos in
tectorio atrioli possim includere,”—I commission
you also to procure me some reliefs to be
inserted in the plaster of the anteroom. And
Pliny in this passage would plainly seem to use
the word in the same sense; otherwise he would
probably have written “forma,” as he did in other
cases when he meant a mould. Not that even
that word would be free from all ambiguity, but
it would more appropriately signify a mould.
But however ingenious is the suggestion of Dr.
Brunn that the passages relating to Lysistratus
ought to belong to Dibutades, the fact is that in
all editions of Pliny they are connected with Lysistratus;
and as this suggestion does not dispose of
all difficulties and clear up the matter, we will
proceed to consider them in that relation, and see
if anything can be made clearly out of them.
Plainly, if the “scientiam” here spoken of refers
to the invention of Lysistratus, and is interpreted
to be the art of casting in plaster, it is
ridiculously incorrect to say that it was older than
casting in brass. If that invention be of modeling
in plaster, it is also entirely incorrect. We know
that this was practiced at least a century previous,—as,
for instance, in the construction of the
great statue of Zeus at Megara, the body of which
was of plaster and clay, the head alone being cased
in gold and ivory; and also of the Bacchus in
painted plaster, of which Pausanias speaks.
The only way in which we can explain the statement
that any “scientiam” or process described
by Pliny as used by Lysistratus was older than
the art of casting in bronze, is by supposing he
meant to say that the process he employed was in
itself an old one, and that it was only in the practical
application to the making of portraits that
there was any novelty,—the process of covering a
core of plaster with wax being older than casting
in bronze, while covering a sketch of plaster with
wax and then working that surface up from life
was new. The statement so understood would be
intelligible at least, and, as far as we know, perfectly
correct. The method of the ancients in
casting bronze statues is not described by any ancient
writer, but it is supposed to have been this:
A fire-proof core was first built up of plaster, clay,
earth, or other materials, and over this a thin and
even coating of wax or pitch was spread; or perhaps,
which is not so probable, the surface was
rasped down to the thickness intended for the
bronze, and afterwards covered with a thin coating
of wax. In either case the result would be the
same. The outside of this wax being then completely
covered with sand or packed clay-dust,
there would be a thin coating of wax inclosed between
the two surfaces, which, melting away before
the fused metal, would allow that metal to take
its place. This would account for the remarkable
thinness and evenness of the ancient bronzes; for
by such a method the core would be perfect, and
the artist would naturally put on as little wax as
possible. If we suppose the statue, after it was
nearly completed in plaster or clay, not to have
been rasped down but simply to have been covered
with wax, we shall see that the result would be
that the bronze cast would be a little fuller in
size and thicker in proportions than the original
model. And this is a peculiar characteristic of
the ancient bronzes, especially to be observed in
the limbs and joints, which are generally larger
and puffier in bronze than in marble statues.
Now if Pliny meant to say of Lysistratus that
his method of modeling portraits by making a
plaster figure or core, and covering the surface
with wax, was older than that of casting in bronze,
he was quite right; for undoubtedly the process of
covering a core with wax must have preceded that
of casting in bronze, or at least must have been
coincident with it. But at the same time this
method had previously been used only, or at least
chiefly, in casting; whereas Lysistratus was the
first to use it for modeling from life and carefully
finishing every part. The process was old; the
application was new.
Thus far in considering this passage we have
proceeded on the hypothesis that the “cera”
spoken of was wax. But another and quite different
view is also possible, and seems in all probability
to be the correct one. Pliny may mean to
refer to quite a different thing, and by the term
“cera” may have meant not wax but color.
“Ceræ” was the common term for a painter’s
colors, and Pliny himself thus uses it in defining
encaustic painting: “Ceris pingere et picturam
inurere.” Varro also says, “Pictores locutulas
magnas habent arculas ubi discolores sunt ceræ.”
Statius also uses the same term when he says,
“Apelleæ cuperent te scribere ceræ.” Anacreon,
in his odes, constantly uses κηρός for picture; as,
for instance,—
Ἔρωτα κήρινόν τις
Νεηνίης ἐπώλει.
Here it is not a waxen figure, but a wax, or oil,—that
is, a painting of Eros, not an ἀγάλμα. And
in the same ode the youth replies in Doric, “Οὐκ
εἰμὶ κηροτέχνης”—“I am not a painter;” or even
more manifestly in the ode beginning,—
Ἄγε ζωγράφων ἄριστε,
γράφε, ζωγράφων ἄριστε,
Ῥοδίης κοίρανε τέχνης,
ἀπεοῦσαν, ὡς ἂν εἴπω,
γράφε τὴν ἐμὴν ἑταίρην.
γράφε μοι τρίχας τὸ πρῶτον
ἁπαλάς τε καὶ μελαίνας·
ὁ δὲ κηρὸς ἂν δύνηται,
γράφε καὶ μύρου πνεούσας.
And again,—
ἀπέχει· Βλέπω γὰρ αὐτήν.
τάχα, κηρὲ, καὶ λαλήσεις.
Wax was the common medium used by painters.
After it had been purified and blanched, their
colors were mixed with it just as ours are with oil;
and in like manner, as we speak of painting in
oils, they spoke of painting in wax. A head done
in chalk would no more necessarily mean a head
modeled in chalk or plaster, than “imaginem [or
effigiem] cera expressam” would mean a likeness
modeled in wax.
The substances on which the ancients painted
were wood, clay, plaster, stone, parchment, and
perhaps canvas. The best painters, however,
rarely painted on anything but tablets or panels.
“Nulla gloria artificum est nisi eorum qui tabulas
pinxere,” says Pliny (xxxv. 37). These panels
were of wood; they were prepared for painting by
spreading over them chalk or white plaster (gypsum),
and on that account were called “λεύκωμα.”
All the paintings on walls were also on plaster
covered with a composition of chalk and marble
dust, as is fully described by Vitruvius.15
Let us now apply these facts to Pliny’s statement.
May he not intend to say, and is not this
a legitimate meaning of his words, that Lysistratus
first of all modeled portraits in gypsum from life,
and then increased the likeness by color laid on to
the plaster bust. He also made colored copies or
effigies from brass statues (which were called, as
we know, “ceræ”), and these came so into vogue
that thenceforward there were no statues without
white clay or chalk, which, as we have seen, was a
preparation for the wax color as shown by Vitruvius.
In this view of his meaning, the statement
that this peculiar process is older than that of casting
in bronze becomes intelligible, if we suppose
him to intend to say that coloring statues was a
very old process, while coloring portraits in exact
imitation of life was the invention of Lysistratus.
The succeeding sentence then becomes clear, in
which he says that the most famous plastæ were
Damophilus and Gorgasus, who were also painters,
and who decorated the Temple of Ceres at
Rome in both these arts, since it is plain that
these works were both modeled and painted.
The making of portraits in effigy, colored in
imitation of life, had been a common practice
in Rome, as we learn from Pliny himself, and
these, because they were colored, were technically
called “ceræ” as well as “imagines.” It was the
custom of the great families to set up these colored
figures in their atria, and on particular festivals
to carry them in procession through the
streets of Rome, draped with actual robes such as
were worn by the persons whom they represented.
Pliny expresses his regret that in his time this
custom had fallen into disuse, tending as it did to
keep fresh and alive the personal memory of great
men who had passed away from this life.16
It will be useful here to consider the character
of the whole chapter in which this passage appears.
It is entitled, “Plastices primi inventores,
de simulacris, et vasis fictilibus et pretio eorum.”
The object of the chapter is to give an account of
modeling and modelers, not of casting. In a
previous chapter, where Pliny is speaking of some
early products of the plastic art, and particularly
of the signa Tuscanica, or earthenware statues, he
says: “It appears to me a singular fact, that,
though the origin of statues was of such great antiquity
in Italy, the images of the gods, which
were consecrated to them in their temples, should
have been fashioned of wood or earthenware, until
the conquest of Asia introduced luxury among
us. It will be most convenient to speak of the
art of making likenesses [similitudines exprimendi]
when we come to speak of what the Greeks
call ‘plastice,’ for the art of modeling was prior
to that of statuary of bronze and marble,—[prior
quam statuaria fuit]. But this last art has flourished
in such an infinite degree that to pursue the
subject thoroughly would require many volumes.”
Thus he announces clearly beforehand what he intends
to speak of in this chapter which we are now
considering, on plasticæ. It is the art of “making
likenesses, of the first invention of modeling, of
fictile vases, and of their price,” but not of casting
or of any such invention. The previous chapter,
in which this announcement is made of his
subsequent intention, is devoted to casting in
bronze and brass-work, or statuaria. After making
this statement, he goes on to enumerate the
principal works in bronze, and then says that portrait
statues were long afterwards placed in the
Forum and in the atria of private houses; that
clients thus did honor to their patrons, and that
in former times the statues thus dedicated were
dressed in togas: “Togatæ effigies antiquitus ita
dicabantur;” or ought not “dicabantur” to be
dicebantur,—meaning that these statues were
called “togatæ effigies”?
In the chapter we are now considering, he begins
by saying that, having already said enough about
pictures, he now proposes to append some account
of the plastic art. Then he speaks of Dibutades,
and relates the story of his making the portrait of
the girl he loved; and adds that he first invented
a method of coloring his works in pottery by adding
red earth or red chalk. Then follows the passage
about Lysistratus, who used plaster instead
of clay to make portraits, covering it with wax or
color to improve the resemblance. After the passages
cited, he goes on to mention other celebrated
modelers (plastæ laudatissimi), among whom
were Damophilus and Gorgasus, who were also
painters, and who adorned the Temple of Ceres at
Rome by the exercise of both their arts. According
to Varro, he says, everything in the temples
was Tuscanica,—that is, ancient pottery of the
Etruscan school; and when they were repaired the
painted coatings of the walls were removed and
framed. He also mentions Chalcosthenes, who
executed several works in baked earth. He cites
Varro again as saying that Possis at Rome executed
grapes, fruit, and fishes with such truth to
Nature that they could not be distinguished from
the real things. Dibutades, he also says, invented
a method of coloring plastic composition by adding
red earth.
Throughout the chapter Pliny is not speaking
solely of modelers, but most of those he mentions
colored their works. The grapes, fruit, and fishes
of Possis, the works of Damophilus and Gorgasus,
the Tuscanica in the temples, all were colored in
imitation of the objects represented. And besides
these he mentions particularly the Jupiter of Pasiteles,
made in clay, “et ideo miniari solitum,”—and
therefore proper for painting in vermilion.
He also speaks of “figlina opera,”—earthenware
painted in encaustic,—which were on the baths
of Agrippa in Rome. All this seems to lend
probability to the interpretation of “cera” to
mean color and not wax; at all events, there is
not a word about casting, unless the words relating
to Lysistratus can be tortured into such a
meaning. What adds still more to the probability
that this was the real thought of Pliny in the
passage cited is the use of the words “effigies”
and “argilla.” “Effigies” in Latin is distinguished
from “simulacrum” (which may be a picture
as well as a statue), both being representations
indicating something which shows they are
not life itself, the one being flat and the other colorless;
while “effigies” carries the idea of deception
with it, so far as resemblance goes. Thus Cicero
says, “Vidistis non fratrem tuum nec vestigium
quidem aut simulacrum, sed effigiem quamdam
spirantis mortui.” So, also, “argilla” means white
clay, and not ordinary clay out of which terra cotta
images were made; and Pliny may have
intended by these words to express the idea that
after Lysistratus had made effigies or colored
copies of brass or marble statues, white clay was
constantly used, for the reason that it was manifestly
better for coloring. This would relieve
him from the absurdity of saying that Lysistratus
invented or led the way in modeling in clay,
rather than in the use of white clay which he colored.
Argilla and gypsum would then be nearly the
same thing, both used as a basis for colored walls,
upon which “cera” or color was laid or infused.
This would clear up the subsequent statement that
this art was older than casting in bronze, since it
is plain that coloring statues was very ancient.
Pausanias mentions two,—one of the Ephesian
Diana and one of Bacchus in wood, gilt except the
faces,—which were painted with vermilion. So,
in the Wisdom of Solomon (ch. xiii. and xv.),
images of wood and clay are spoken of, painted
in red and vermilion and stained with divers colors;
and in 630 B. C. there were images in gold,
silver, stone, and wood in Babylon (Baruch, ch.
vi. and xiii.), painted and gilded and dressed, and
colored purple.
In his chapter entitled “Honos Imaginum,”—the
honor attached to portraits,—Pliny says it
was the custom of the Romans to adorn their palæstra
and anointing-rooms with the portraits of
athletes (“imaginibus athletarum”), and to carry
about on their persons the face of Epicurus (“vultus
Epicuri”); and that they also prized the portraits
of strangers (“alienasque effigies colunt”).
Afterwards, contrasting the habits of the Romans
of his own day with those of the ancient Romans,
he says: “And since the former have no longer in
them any likeness to the minds of their ancestors,
they also neglect the likeness of their bodies. How
different it was,” he continues, “with our ancestors,
who placed in their atria to be gazed at these
‘imagines,’ and not statues by foreign artists in
brass or marble, and kept colored portraits of their
faces each in its separate case, to serve as ‘imagines’
to accompany their funerals.”17 It would
seem from this that, besides the draped images or
effigies in the halls, modeled and colored busts of
others of the family, probably of less distinction,
were also kept to be dressed up on occasion, made
into effigies, and carried in procession. Other
“imagines” of the most distinguished personages
in the family were placed outside at the threshold
of the house, hung with the spoils of the enemy.
It is of these “expressi cera vultus” and these
“imagines” kept by the Romans as proofs of their
nobility, and on which their pedigrees were inscribed,
that Ovid speaks when he says,—
“Per lege dispositas generosa per atria ceras.”
On the sale of the house they were not allowed to
be destroyed or removed, but passed with it, and
were bought by “novi homines” (men of no family),
and passed off by them as the portraits of
their own ancestors,—just as the portraits of Wardour
Street are at the present day. Cicero in his
invective against Piso cries out, “Obrepsisti ad
honores errore hominum, commendatione fumosarum
imaginum, quarum simile habes nihil præter
colorem;” and Sallust in his Jugurtha says,
“Quia imagines non habeo, et quia mihi nova nobilitas
est.”
Nor were the Romans singular in this custom of
draping figures with real stuffs. The images of
the gods in early Greece also were draped and
dressed in clothes, and crowns were placed on their
heads. They had false hair, too, which was
dressed regularly by attendants, and at stated
times they were washed and adorned with jewels
and had their dresses arranged, just as if they were
alive. In later times this custom died out; but
the colossal Athena’s solid drapery of gold was
washed at a certain festival appointed for the purpose,
called Plyntheria. In Rome, however, the
custom was maintained to a late day. The images
of the temples were adorned with real drapery,
and purple mantles were hung on the statues of
the emperors. The Greeks did not thus treat
their portrait statues, and in this the Romans were
peculiar.
The Roman “imagines” and “ceræ” were probably
executed in plaster or some such material, certainly
not in marble, or otherwise they would have
been too heavy to be carried about in procession.
Apparently they resembled the figures which Lysistratus
first began to make, and the process of
coloring them, if we understand “cera” to mean
color, was little else than the old practice, called
“circumlitio,” of covering marble statues with an
encaustic varnish of color so as to give them a delicate
and tinted surface. The most salient example
of this is to be found in the anecdote told of
Praxiteles, who, when he was asked which of his
statues he most admired, answered, “Those that
Nicias has colored,”—“quibus Nicias manum admovisset,”—Nicias,
who in his youth was celebrated
as a painter of statues, ἀγαλμάτων ἐγκαυστής,
having assisted him, “in statuis circumliendis.”
A similar process, called καύσις, was also employed
in finishing walls, and is thus described by Vitruvius:
After the wall had received its color, it was
covered with Punic wax and oil, which was laid on
evenly with a hard brush, and then half melted or
infused into a smooth surface by moving a “cauterium,”
or pan of hot coals, close over it; and after
that it was rubbed with a candle and a clean linen
cloth.
This process, then, was old as applied to marble
statues and to plaster walls. What was new in
the work of Lysistratus was that he united the
two methods, by modeling in plaster the general
likeness and then finishing the surface in encaustic.
It was an old process with a new application.
To explain such a process, what could be clearer
than the words Pliny uses? We do not need to
warp a word from its ordinary significance. Lysistratus
made portraits in plaster from life, and
improved them by color laid on to the model. He
thus made realistic, exact resemblances, whereas
before him artists had sought only to make heads
as beautiful as possible.
What, then, were the “effigies de signis” that
he made? We have already seen that the term
“effigies” had a significance of reality and absolute
imitation, and corresponded in great measure to
the English word effigy, meaning colored effigies
with real dresses,—like those of Madame Tussaud,
for instance. The “imagines” and “ceræ” of the
ancient Romans were very much like them; and
does not Pliny mean to say that Lysistratus copied
marble or brass statues, or pictures, and made these
effigies from them, coloring them so as to add to
the likeness, and clothing them with real draperies?
and that this so grew into vogue that thenceforward
there were no statues which were not thus
copied in plaster or “argilla”?—using the term
“argilla,” or white clay, as equivalent to gypsum,
with which possibly the plaster was mixed. As
“argilla” was the foundation with which the ancient
panels were prepared for painting, this would
seem most appropriate in such case.
Such would be the figures alluded to by Lucian,
or by Lexiphanes when he says, “If you cull the
flower of all these various beauties, you will in
your eloquence be like those makers of figures in
wax and clay [or argilla] in the Forum, colored
outside with minium and blue, and inside only
fragile clay.”
According to this interpretation of the passage
in Pliny, it not only becomes intelligible as a
whole, but is consistent and without contradiction;
whereas, if we suppose that he meant to indicate
the process of casting in plaster, his statements
are not only entirely obscure and inconsecutive,
but ignorant and contradictory.
In the previous chapter we have critically considered
the text of Pliny bearing upon the question
whether the ancient Greeks and Romans were
acquainted with the art of casting. Let us now
proceed to some general considerations as to the
probability that this art was known and practiced
by them.
In the first place, the distinction between modeling
and casting must be constantly kept in mind,
and care must be taken not to confound the two
totally different terms “mould” and “model.”
That gypsum was used in modeling there can be
no doubt, and it is quite possible that it may have
been used to fill prepared moulds of stone, terra
cotta, or other materials for the making of ectypa.
There is indeed no proof of this; but as we know
that moulds were made and cut in stone, into
which clay was pressed, to be then withdrawn and
baked for ectypa with which to adorn houses, so
also it is possible that gypsum may have been
used for this purpose. This, however, is merely a
supposition, and the fact that none of them have
ever been found in plaster renders it highly improbable.
In these ectypa of clay, as well as in
the impressions taken from them, there are no indications
of anything like what we call a piece-mould,
composed of many sections; and whenever
there are under-cuttings in the ectypa, which could
not be withdrawn from the mould and which
would fasten them into it, these parts of the
ectypa are invariably worked by hand. For instance,
in the collection of Mr. Fol in Rome there
are several terra cotta figures of low relief evidently
stamped from a mould, which are appliqué,
or fastened subsequently to the cista of which
they form a part. The sutures under each figure
are still visible, but they are all corrected and
worked by hand after being withdrawn, and have
evidently suffered in being removed from the
mould. In the same collection there are several
specimens of plaster reliefs, with such deep under-cuttings
that they could not have been withdrawn
from a single piece-mould; but all these under-cuttings
are freely worked by hand, showing plainly
that they were not in the stamp or mould; and it
is also clear that they were afterwards worked
over with fluid plaster, the edges and flats of
which have not been rounded, but left as it was
freely laid on by hand. It is probable that in
these cases plaster was pressed into a mould in
the same manner as clay, and afterwards worked
up and finished. But the slightest examination
will show clearly that if a mould was employed
to give a general form to them, it certainly was
not a piece-mould; and that they are not castings
in the modern sense of the word, but only rude
stamps.
These are the only specimens, however, so far as
we are aware, of any such use of plaster for low-relief
ornaments,—the ectypa which have been
preserved to us being invariably of baked clay.
If plaster had been used for this purpose, we
should expect to find casts in the interior of houses
or tombs, where they would be protected from the
weather, and where they could be easily introduced
into the walls and ceilings. But though
elaborately ornamented designs in relief, worked
in gypsum, are to be found still fresh and uninjured
on the ancient tombs and baths, all of them
were freely and rapidly modeled by hand while
the gypsum was still fresh and plastic, and not a
single specimen of cast plaster has been found. It
is but a few years since the tombs in the Via
Latina were opened, and in two of them the ceilings,
divided into compartments, were covered
with rich and fantastic designs of flowers, fruit,
arabesques, groups of imaginary animals, sea-nymphs,
and human figures; the designs varying
in each compartment, and all modeled in the
plaster with remarkable vivacity and spirit: not
one of them was cast. So in the houses at Pompeii,
not a vestige of a figure or ornament cast in
plaster has ever been found,—nor a mould in
plaster; and when one considers that, being completely
protected, they would naturally have survived
as well as other far more fragile and destructible
objects which have been preserved, the
evidence is almost absolute that they never could
have existed there. If so, it is in the highest
degree probable that they existed nowhere. It
would seem plain, then, that even the first, simplest,
and most natural processes of casting in gypsum
were unknown to the ancients, for no other
process is so easy and simple as to fill a flat mould
with plaster and then remove it, provided there
are no under-cuttings. In doing this, however,
there is a slight practical difficulty if the mould
is in one piece, as the least under-cutting would
render it impossible to remove the cast without
injury or breakage. Indeed, though there were
no under-cutting, it would at least be very difficult
to remove the plaster from a mould in one
piece. Clay would be removed with far greater
ease because of its pliancy, and any cracks or imperfections
could be at once remedied; add to
this that baked clay is one of the most enduring
of materials, and we have the probable reasons
why the ancients used it instead of gypsum. But
whatever may have been their reasons, it is perfectly
clear that they did use clay; and we have
no evidence that they ever used plaster.
This use of gypsum to take impressions from
flat moulds is suggested by Theophrastus, it would
seem, in his treatise on mineralogy,18 in which he
says that plaster “seems better than other materials
to receive impressions.” The term ἀπόμαγμα
means nothing more than an impression, such as
one makes in wax from a seal ring, and such as is
common still in plaster; it is to this use that he
seems to refer. He does not say, however, that
gypsum was really put to this use; and if it were,
it would advance us little in our inquiry, since any
material which is soft will receive an impression,
whether it be bread, pitch, clay, wax, or any similar
substance.
But the step from this simple process of stamping
in a shallow mould to casting from life or
from the round is enormous. The difficulties are
multiplied a hundred-fold. It is no longer a
simple operation, but a nice and complicated one.
The part to be cast must first be oiled or soaped,
then covered with plaster of about the consistency
of rich cream, then divided into sections while the
material is still tender, so as to enable the mould
to be withdrawn part by part without breakage,
then allowed to set, then removed, oiled or soaped
on the interior surface, the parts all properly
replaced, fluid plaster poured into the mould,—and
finally, after the cast is set, the mould must
be carefully removed by a hammer and chisel.
This is an elaborate process as applied to an arm
or a hand, but when applied to a living face it is
not only difficult but disagreeable, and unless due
care be used it may be dangerous; and after all
a cast from the face is hard, forced, and unnatural
in its character and impression, however skillfully
it may be done, and can only serve the sculptor
as the basis of his work. Yet if the common interpretation
of the passage in Pliny be accurate,
this is the process which was invented and practiced
by Lysistratus, and by means of which he
made portraits. Credat Judæus! With all our
knowledge and practice, we do not find this to
answer in our own time.
But to cast from a statue in clay is still more
difficult and complicated; there the extremest
care and nicety are required in making the proper
divisions, in extracting the clay and irons, recommitting
the sections, and breaking off the outer
shell of the mould. In fact, the modern process
is so complicated that no one can see it without
wondering how it ever came to be so thought out
and perfected, or without being convinced that it
must have been slowly arrived at by many steps
and many failures.
That statues were modeled in plaster by the
ancients there is no doubt. Pausanias mentions
several;19 and Spartianus20 also speaks of “Three
Victories” in plaster, with palms in their hands,
erected at one of the games,—and says that on
one of the days of the Circensian games when according
to common custom they were erected, the
central one on which the name of Severus was inscribed,
and which bore a globe, was thrown down
by a gust of wind from the podium, and that
another bearing the name of Geta on it also fell
and was shattered to pieces.
Firmicus21 also relates that after Zagreus, son of
Jupiter, was slain by the Titans, his body was cut
to pieces and thrown into a cauldron, from which
Minerva rescued the heart and carried it to Jupiter.
He then gave it to Semele, who resuscitated
Zagreus, and Jupiter afterwards preserved his
likeness in plaster,—“Ex gypso plastico opere
perfecit.”
Mr. Perkins cites all these instances, and says:
“They authorize us to believe that the Greeks and
Romans practiced casting in plaster.” But in
saying this he altogether overlooks the very plain
distinction between the two entirely different operations
of casting and modeling. We know that
they modeled in plaster; the only question is
whether they cast in that material. The term
for casting, as we have stated, was “fundere,” and
is always used when real casting in brass or other
metal is spoken of; but nowhere is the term “fundere”
applied to any work in gypsum. “Ars
fundendi æro” is constantly spoken of,—“ars
fundendi gypso” never. Besides, the very phrase
“ex gypso plastico opere perfecit” is at variance
with casting. The words “plastico” and “opere”
mean modeling, and nothing else.
But throughout this paper by Mr. Perkins these
two completely distinct processes are constantly
confounded with each other. It suffices for him
to find a statement in an ancient writer that anything
is made in plaster, or even an allusion to a
plaster statue, and at once he jumps to the conclusion
that the statue was necessarily cast, and not
shapen or modeled.
“It remains for us now,” he says, “to establish
by undeniable proof how little foundation there
is for the opinion of those who pretend that the
ancients did not make use of plaster for casting,
supporting their opinion on the complete absence
of statues and statuettes in plaster, or fragments
of any kind found in excavations, when nevertheless
thousands of objects of the frailest kind are
found, such as stuccoes, vases, terra cotta, glass,
wax heads, etc. If it be true that the inclemencies
of weather and atmospheric agents could cause the
disappearance of plaster saturated with humidity,
or placed in conditions favorable to its destruction,
it does not necessarily follow that these conditions
always reproduce themselves. It suffices, to convince
one’s self of this, to glance at the plates 67,
76, 85, in the magnificent work published at St.
Petersburg on the antiquities of the Cimmerian
Bosphorus. These plates represent plasters preserved
in the Museum of the Hermitage, coming
from a tomb on Mount Mithridates opened in
1832, and from another tomb at Kertch excavated
in 1843. These plasters date back to the fourth
century before our era.22 Adorned with various
colors and executed in relief, they were destined
to be attached as ornaments to other objects, such
as sarcophagi, pilasters, walls, etc.”
Well! what if they were? Is this any proof
that they were cast? Mr. Perkins is easily satisfied,
if he is assured of this fact by looking at
engraved plates. Are they all of the same size?
Are they identical, as they would be if they were
cast from the same mould, or are they like all
other plaster and stucco work of the ancients of
which we are cognizant,—ornaments modeled by
hand? or are they pressures from a flat, shallow
mould, like the ectypa? If the latter, they are
almost unique; and so far they prove that the
artists who made them understood this first and
simplest process of casting, or rather of stamping.
But from plates it would be impossible to determine
this fact, and Mr. Perkins gives us no reason
to think they are unlike all the other ancient
stucco work. He does not profess to have seen
and examined them for himself; at all events, one
fact is clear, that these, if they are in plaster, are
painted plaster.
In the British Museum there exist some of these
so-called casts in plaster from Cyrenaica and from
Kertch. Undoubtedly they are nearer to being
true casts than anything else which has as yet been
discovered; but, after all, a careful examination
of them will show that they are not casts in the
legitimate sense of the word, but merely stamps
for a mould, and fashioned in precisely the same
way that was employed in making the hollow
terra cottas. To make these, a very rude stamp
was executed, with no under-cuttings of any kind,
everything being filled up which could impede the
removal of the clay, which was pressed into the
stamp, then carefully extracted again and finished
by hand. All the terra cotta reliefs called ectypa
were made in this way, and some of the moulds
still exist,—not one of them, however, in plaster.
The same process was employed to make some of
the figures of terra cotta in the round, by making
a mould of two pieces divided in the middle, of
a very generalized form, with no under-cuttings.
Into each of these moulds a quantity of clay was
squeezed; the two parts were then removed carefully,
and joined together. A general form was
thus obtained, and the artist proceeded to model
and to finish it with more or less care. In this way
not only ectypa were made in clay and afterwards
baked, but also small flat ornaments which were
afterwards appliqué, or fastened on to flat or round
surfaces,—as on to cista. This is the process by
which fragments of the figures from Cyrenaica
and Kertch in the British Museum were made. The
junction of the two halves is clear. The work is
very rude; there are no under-cuttings; everything
is filled up which would in the least impede
the withdrawal of the material from the stamp.
There is, for instance, an arm and hand, with the
interstices of the fingers quite filled up. But
what clearly proves that these figures were not
cast, as distinguished from stamped, is the head.
Here the hair being adorned with a wreath with
under-cuttings, it could not be withdrawn from the
stamp without destroying it, and it is entirely appliqué,
or worked on to the head after it was removed.
Had it been cast, there would have been
no such difficulty. Nor, again, is it quite clear
that the material of these figures is pure gypsum.
It would rather seem to be a mixture of gypsum
with white clay, or argilla, to give it flexibility,
and enable it to be withdrawn from the mould.
Indeed, it may here be observed that it is in every
way probable that the gypsum used by the ancients
in modeling and ornamental work was differently
prepared from that which we now use, and
was mixed with some material which prevented
it from setting rapidly, and gave it strength, ductility,
and plasticity. Otherwise it is difficult to
see how such works as those in the tombs of the
Via Latina, which no one can doubt are modeled
by hand, could have been executed with at once
so much finish and freedom. Gypsum, as we use
it, would set too soon to enable us to work it in
such a manner. In the tombs of the Via Latina
which were lately discovered, it is worked as freely
as if it were clay, and was plainly so prepared as
to enable the artist to take his own time in modeling,
without fear of its hardening—or, as we
call it, setting—immediately.
This, then, is nothing new. It is not casting,
and these figures are not casts. They are stamps,
just like the ectypa of terra cotta. We know that
κοροκόσμια or dolls were anciently made in this way
of wax and gypsum, or of terra cotta; and these
are κοροκόσμια.
To infer from the fact that the Greeks knew
and practiced the art of pressing into shallow
moulds of stone, without under-cuttings, either
clay, pitch, wax, or plaster, that they also understood
and practiced the art of making moulds and
casts from life or from the round is utterly unwarrantable.
Nothing is more simple than the one
art, while the other is extremely complex. The
one is merely like making an impression from a
seal, which would naturally suggest itself to the
first person who left the pressure of his foot in
clay or mud; the other requires various processes
of calculation and invention. In inventions it is
not always or ordinarily the first step which costs,
but the subsequent and calculated steps. Centuries
often elapse between the first step and the
second. A remarkable instance of this is to be
found in the history of the invention of printing.
The first steps to this wonderful art were taken by
the ancient Romans; the very process by which
we now print was known and practiced by them;
but the application of it to the printing of books
does not seem to have occurred to their minds. It
cannot, however, but appear most extraordinary
that the idea of printing should not have occurred
to them when we consider the facts of the case.
Pliny relates that Cato published a book containing
portraits of distinguished persons of his time,
of which there were many copies; and so far as
we can conjecture, these copies were probably
stamped on parchment or some such material, and
afterwards colored. Putting this together with
the fact that ancient bricks have been lately found
in Rome with names and numbers stamped upon
them by means of movable types, so that the numbers
or letters could be arranged at will, we might
absolutely state that the ancient Romans understood
and practiced the art of printing. They
certainly did print on their brick; they probably
stamped the portraits of cuts in their books,—but
so far as we know they never united the processes,
and never stamped a book with movable
types. Adopting Mr. Perkins’s method of argument,
we might declare, however, that the mere
fact that none of these printed books have ever
come down to us was entirely inconclusive, since
these books might have utterly perished; while
we have the clearest proof that they did print with
movable types on brick, and therefore it is plain
that they invented printing. The step from one
of these processes to the other does indeed seem so
evident, so natural, almost so inevitable, that we
are puzzled to imagine how they could ever have
overlooked it. Yet there is little doubt that they
did. But from the simple fact of stamping in
clay or plaster to the complex process of making
moulds and casts in the round requires not one
step but many, and each one of them requires
calculation and invention. Indeed, if the art were
now to be lost, it would be easy to conceive that
centuries might pass before it would be reinvented.
In the collection of Mr. Fol of Rome, of which
we have heretofore spoken, there are some interesting
fragments of ancient statuettes in the round,
very carefully finished in plaster, being the leg and
thigh of one, and the half-breast and a portion of
the torso of another. These are as carefully finished
as if they were in marble, but they are elaborately
worked by hand in the plaster, and not cast.
These are exceedingly interesting as showing the
method of the ancients in working in plaster, and
they clearly illustrate the process of Lysistratus as
described by Pliny,—the only difference being
that the surface is of gypsum and not of wax, or
color. The interior or core of these fragments,
which is solid, is of lime, or a coarse kind of gypsum,
and over the surface of this core is spread a
thin coating of fine gypsum, which has been elaborately
worked and smoothed on while it was fluid.
The touches and creases on the surface are those of
a modeler’s hand and stick, and it differs in every
way from a cast. It is therefore plain that the
artist first made a core, or rough “imaginem” or
“formam,” of coarse gypsum, and that he improved,
emended, and finished the surface, not by means
of “cera infusa in eam formam gypsi,” but of
gypsum spread over it,—just as Lysistratus did.
The language of Pliny is an exact description of
this process.
Again, a strong negative indication that gypsum
was not used for casting, or indeed to any extent in
modeling, is to be found in the chapter by Pliny on
gypsum. “Its use is,” he says, “to whitewash
[or parget], and to make small figures to ornament
houses, and for wreaths.” He also adds that it is
a good medicine for pains in the stomach; but he
entirely omits to mention that it was ever used for
casting. Is it possible to believe that if it were so
used he would not have alluded even to such a
fact? Would it be conceivable that at the present
day a chapter could be written on plaster of
Paris, omitting its employment for the purpose of
casting? After giving us this enumeration of the
uses to which gypsum is applied, Pliny goes on to
describe its nature, tell where it is found, and
name the different kinds; and he concludes with
no allusion to any other use than what he has previously
stated.
Again, Pliny in the chapter on Lysistratus—which
it must be remembered is devoted to modeling—mentions
one fact which seems to be inconsistent
with any knowledge at that time of casting.
Arcesilaus, he says, modeled a drinking-cup or
mixing-bowl in plaster, which he sold to Octavius,
a Roman knight,23 for a talent (£250). It is impossible
to believe that such an enormous price
would have been given for a mere plaster bowl. If
the process of casting from it was then understood,
Arcesilaus might have repeated it in cast a thousand
times, and the original and the cast being in
the same material, one would have been quite as
good as the other, if retouched. Yet he seems
only to have made one, and to have asked a talent
for that. Again, Lucullus made a contract with
this same artist to model for him in plaster a
statue of Fabatus, for which he agreed to pay him
no less than 60,000 sesterces, or £530.
It is worth noting, too, as a curious fact, that
just at the very time when Lysistratus is supposed
to have invented plaster-casting, the art of brass-casting
began to decline in character and style,
and soon after seems to have died out and been
lost; at all events, Pliny tells us that soon after
the 120th Olympiad the art perished,—“cessavit
deinde ars.” And as Lysistratus lived only about
twenty-five years previously, it would be singular
to find one of these arts dying out just as the other
was being developed.
Mr. Perkins also thinks it valuable to tell us
that Canova was of opinion that the sculptors of
antiquity made finished sketches, and then by
means of proportional compasses enlarged them and
took points on the marble; and he adds, “We
should weigh these words of a great sculptor who
devoted himself to the most minute researches on
this subject, as well as to everything that had
relation to the fine arts.”
We agree that we should weigh the words of
this distinguished sculptor, though we were not
aware before that he was a profound archæologist,
or had made minute researches on this subject.
But how in any way does this tend to prove that
the ancient Greeks and Romans knew how to cast
in plaster? We are equally unable to see the precise
bearing on this question of the fact also stated
by him, that the drill is supposed by some to have
been invented by Callimachus, and by others to
have been used long before; or that the pointing
of a statue was probably known to the Greeks, and
certainly to the Romans.
Yet in a certain way the opinion of Canova that
the ancients made small sketches, and by proportional
compasses transferred their proportions,
measures, and general forms to their large works,
has an argumentative relation to the subject different
from what Mr. Perkins probably supposed.
This opinion is undoubtedly well founded, and
accepting it as such, what does it indicate? That
the process of casting in plaster was known to
the ancients? By no means. So far as it goes,
it proves diametrically the opposite,—as Mr.
Perkins might have seen, had he weighed the
words of this great sculptor.
In fact, this leads us to one of the strongest arguments
against the opinion apparently advocated
by Mr. Perkins. Had the ancients known how to
cast in plaster from the model, as they knew how
to cast in bronze, this process of making small
statuettes and enlarging therefrom would have
been quite unnecessary. They would thus have
escaped the incorrectness which is unavoidable in
such a process, by at once making their models of
full size, and completely finishing them in clay or
other plastic material before transferring them to
the marble. Their process probably was to make
a small statuette in clay, and then bake it or dry
it. But in transferring proportionally this small
figure into a large one, an objection occurs. Defects
scarcely perceptible in a small figure become
gross defects when multiplied into a large one.
Not only variations of one eighth of an inch more
or less in small particulars in a figure a foot high
would alter entirely the relative proportions of a
figure eight feet high, but other inaccuracies inevitably
occurring in enlarging by proportional compasses
would increase these disproportions, so that
the increased figure would be invariably untrue in
its effect and in its measures. Now this is precisely
what is apparent to any one who carefully
studies the antique statues. Even in works showing
the highest artistic knowledge and skill, the
want of correspondence of measures and proportions
between the two sides of the figure is very
manifest; and the larger they are the more this is
exhibited. Thus, to take one of the highest examples,
in the Theseus we find astonishing knowledge
and artistic skill in treatment, beside disagreements
of measurement in corresponding parts,
which are evidently the result of the defective
mechanical process of enlargement. The legs are
beautifully modeled, but of unequal length,—one
being much longer in the thigh than the other.
The same observation is true of the clavicle, and
indeed throughout the statue. Now even an inferior
artist would have seen and avoided these
mistakes in modeling the statue full size, but the
defect would be easily passed over by the eye in
the small sketch, particularly if the statuette were
merely a sketch, as was in all probability the usual
case. It would be difficult to believe that an artist
with the mastery shown in this statue would not
have seen and corrected these mistakes, had the
model of this figure been of the same size. This
of course he perceived after the points were taken
in the marble and the work was roughed out, but
then it was too late to remedy them. This difficulty
he and all other artists must constantly have
felt. The question was how to avoid it. Nothing
could have been more simple, if the modern process
of casting in plaster from the clay model had
been known to them. They would simply have
modeled the statue in clay of its full size, cast it in
plaster, and been sure of its exact proportions and
measures.
Let us take one step further. Had they understood
the modern process of casting in plaster
from the clay or from a statue, they could from the
cast have multiplied in marble the same statue any
number of times, identically or with such minute
differences as few eyes could perceive. The repliche
in a modern sculptor’s studio are scarcely to
be distinguished from each other, and there would
have been no difficulty in doing the same thing in
an ancient sculptor’s studio. What is the fact
known? So far from this being the case, not only
are there comparatively very few repliche even of
the most famous statues, for which there would
necessarily be a great demand, but even in the
various repliche which we have there are not only
no two which approach to identity either in attitude
or in size, but one can scarcely say of any of
them that the artist had more at best than a vivid
recollection of the original or of some other replica,
much less that he had it before him to copy even
by eye. Often the attitude is changed, as well as
the size and proportions; sometimes the action is
reversed; and in all cases such differences exist
as it is impossible that the clumsiest workman
could have made with a cast of the original before
him. Nor do we read or hear of any copies in our
sense of copy; that is, exact reproduction of any
of the great works of the great sculptors. Look,
for instance, at the Venus of the Capitol and the
Venus de Medici and the St. Petersburg Venus;
they are all repliche of the renowned statue by
Praxiteles, but beyond the general attitude there
is no resemblance, not so much as any clever artist
of to-day could make from mere recollection. Look
again at the portrait busts; how many are there
of Marcus Aurelius, Octavius Cæsar, and Lucius
Verus!—and no two of them approaching identity.
Of the thousands of statues which have been
excavated, no two are exact copies from the same
model. There is at best nothing more than a
family resemblance among those which are most
alike. Would this be possible, if the ancients
knew and practiced the art of casting in plaster as
we do? It would seem to be utterly impossible,
or at least improbable to the highest degree.
Again, why should not the great artists themselves,
or their scholars, have made repliche of
their famous statues? Nothing would have been
easier had there been any casts from them. They
were greatly coveted, and the prices paid for the
original works were enormous,—so enormous that
the largest prices of our day shrink into insignificance
beside them. For the famous nude Venus
by Praxiteles, Athens, in her extreme desire to
possess it, offered in exchange to pay the whole
public debt of the state to which it belonged.
This offer, however, was peremptorily refused. Yet
what could have been more easy, had a cast of it
been in existence, or had they known how to make
one, than for Praxiteles or his scholars to have
made an exact replica, fully equal to the original
or even superior to it, with additional touches of
the master’s hand? That this was never done, or
hinted at, proves that, the statue once having
passed out of the artist’s hands, he could repeat it
from memory only by aid of his sketch; and this
would not only have cost him as much labor as
making a new statue, but would in no sense have
been identical. Again, is it to be supposed that if
Polyclitus had an absolute cast of his life-size
statue of the Doryphoros which would have enabled
him to repeat it with exactness, the original
would have commanded such a price as one hundred
talents, or £25,000? Or is it possible to
suppose that Arcesilaus would have received a
gold talent (£250) for a plaster bowl which could
have been repeated by casting, for almost nothing?
It was because it was modeled, and the modern
process of casting in a piece-mould was unknown,
that it commanded such a price. Here making
a rude stamp without under-cuttings would not
suffice. The finesse of the work could not be
given, and the work would have been destroyed or
greatly injured in the attempt.
If it be a fact that the Greeks and Romans
knew this process, one would naturally expect to
find at least some fragments of casts or moulds in
plaster of their great works,—as for instance of
their small and exquisite Corinthian bronzes, if not
of their large figures. But, so far as we are aware,
nothing of the kind has ever been found. The
whole city of Pompeii in the height of its luxury
was buried under a fall of ashes, which for many
long centuries preserved the most refined, fragile,
and delicate utensils and works of art; and it is
but a few years since that we removed these ashes
and explored its houses and rooms which had been
untouched since that fatal calamity befell them
of which Pliny gives us so vivid an account. It
is on the statements of the younger Pliny himself
that those rely who claim that the ancients knew
and practiced casting in plaster. Long before his
day, then, this art had been invented; and we
should naturally expect to find some specimens of
it in this city of luxury, among its pictures, its
vases, its statues, and its glass. But in all Pompeii
there has not been found a vestige of a casting in
plaster. Its stuccoes still remain, the bas-reliefs
worked in plaster on its walls are still uninjured,
its paintings are still fresh, its vases unbroken, its
household utensils perfect. Hermetically sealed
up under that mound of ashes, there was nothing
to injure a cast in any house, if it existed. But
there is absolutely nothing of the kind. Yet this
was a people devoted to art, and whose houses
were filled with knick-knacks of every kind. We
find the sculptor’s studio, but there is not a
cast in it, nor is there the shop of a caster. It
is plain, therefore, that there was not a cast in
Pompeii.
But if anywhere there were casts from the round
there were also piece-moulds from the round.
Where are they? Has any person ever heard of
one? Now a hollow cast is comparatively a fragile
object; but a plaster mould, saturated as it
must be with oil, is anything but a fragile object.
Sheltered from the inclemencies of storm and rain,
it would last for thousands of years, and would
even resist a century of exposure to the weather
of Italy. But not underground nor aboveground
anywhere has such a thing been found. Whatever
moulds have been found are fit only for
mere stamping. They are extremely rude, without
under-cuttings, and seem merely to give a general
shape. They are not cast upon anything,
but worked out by hand, and are not in plaster.
They are all small; nothing ever has been found
which is either a mould, or a cast from life, or
from a statue, or from a vase or bowl, or any careful
work of art.
An ancient manufactory of terra cotta has been
lately discovered and unearthed at Arezzo in Tuscany,
and a large number of moulds was found,
taken apparently from vases executed originally on
some hard metal, probably in silver. The figures
on these moulds are of the most exquisite design
and execution, and for beauty and delicacy of finish
exceed anything which remains to us of Greek or
Etruscan art. There are no under-cuttings, and
the relief is so low and flat as to yield an impression
scarcely, if at all, higher than a seal or intaglio.
All these moulds, however, are in terra cotta.
Not one is in plaster, though in this material they
could have been executed more easily and exactly,
and could have been reproduced in the original
size. Of course, first taken, as they were, in soft
clay, then baked, they of necessity shrank in size
and were subject to warping and cracking, all
which defects would have been avoided had they
been made in plaster. All this would indicate that
the use of plaster in making moulds was not practiced
at that period, even in such a simple operation
as this.
In face of this we must say we do not agree
with Mr. Perkins when he thinks he “establishes
by undeniable proof how little founded is the
opinion of those who pretend that the ancients did
not practice casting in plaster,—sustaining it by
the complete absence of statues and statuettes of
plaster or fragments of any kind in the excavations,
when nevertheless thousands of objects are
found of the most fragile nature;” and especially
when the undeniable proof which he offers is the
existence of some works and arabesque ornaments
in plaster found at Kertch, and supposed to belong
to the fourth century before the Christian era, and
which apparently he has never seen. On the contrary,
we should like to know how he explains the
fact that no indubitable ancient moulds or castings
have ever been found.
But Mr. Perkins does not seem to reason beyond
his texts. He does not discuss the probabilities of
the case; he does not undertake to account for, or
to harmonize with his view, the great fact that
nothing has been found of ancient art cast in
plaster. Outside of what is written in books he
does not venture. He does not even seem to have
a clear opinion of his own. He says, “Sur ce point
[casting in plaster] les textes nous laissent dans
les ténèbres. Faut-il s’en étonner? Non! Les
auteurs classiques trompent notre curiosité sur des
choses d’un bien autre intent. Que nous disent-ils
des vases peints, dont les musées de l’Europe regorgent?
Rien,” etc. Well, if the texts leave us
in darkness, are we then to know nothing and to
think nothing? Are we not to exercise our minds,
and if a doubtful text seems to indicate a fact
utterly at variance with our reason and with the
facts we know, are we to treat that text as a
fetich, and bow down and worship it, because it is
written in a book? Are we to endeavor to wrench
everything into harmony with it? Or, if it will
not agree with facts of which there is no doubt,
are we not rather to sacrifice the text than our own
reason? And especially, are we to pay such reverence
to a doubtful text of Pliny, the most careless
of writers, the least accurate of archæologists? As
to the painted vases, no argument or ancient texts
are needed; there is no question in respect to them;
they existed in great numbers; but in respect to
casting in plaster there is nothing but texts to depend
upon. Nay more, there is only one passage
in any ancient author, so far as I am aware, that
seems to assert the existence of this process; and
the question is as to the meaning of this very ambiguous
passage. If it means what Mr. Perkins
supposes, where are the moulds; where are the
casts; where are the finished likenesses; where is
there anything, in a word, to support the statements
of Pliny, as thus interpreted? Does it not
seem amazing that they should all have totally
disappeared?
That the text of Pliny, on which all rests, does
not mean what it is supposed to mean by Mr. Perkins,
we have endeavored to show; but at all
events, since it is admitted to be most obscure and
scarcely intelligible, it would be better to throw the
text overboard, if it is in conflict with all we know
and is improbable in itself, particularly when we
take into consideration the corrupt condition of
the entire text of Pliny. Dr. Brunn, who is certainly
an able and learned archæologist, does not
hesitate to reject a portion of this very text, from
the words “idem et de signis effigiem exprimere,”
as an interpolation; and there can be no doubt in
the mind of any one who carefully examines it
that this entire passage is full of confusion of ideas
and statements.
Mr. Perkins endeavors to strengthen his position,
and also the text of Pliny as he understands
it, by a citation from the “Tragic Jupiter” of Lucian,
in which the statue of Hermes complains
that he is spotted by the pitch with which the
sculptors cover his limbs every day, “afin de les
reproduire,” he gratuitously adds, with no authority
in the text for such a statement; and apropos
of this he tells us that one may “model with
pitch mixed with marble dust or brick.” He adds:
“It is what the Italians call ‘ciment,’ and they
employ it for the most delicate parts of the mould.
It is sufficient in order to keep it in a malleable
state to set the piece on which one is working near
the fire, or to soften it from time to time in a bath
of hot water.” “Now this information,” he continues,
“which we owe to one of the most eminent
and learned artists of our age, is very precious,
since it gives us the real meaning of the passage
in Lucian.” This taken in connection with a
passage in Apollodorus representing Dædalus making
a statue to Hercules ἐν πίσσῃ or ἐν πίσῃ—the
word is doubtful—induces Mr. Perkins “to conclude,
first, that two centuries before the Christian
era, pitch was used, mixed without doubt with
other substances, to cast statues [mouler les
statues]; second, that the passage in Lucian not
only contains one of those railleries of which the
Voltaire of antiquity was so prodigal, but leads us
to suspect that it veils the indication of one of
the processes of casting.” That is, first he inclines
to the opinion that πίσσῃ (pitch) is a misprint for
πίτυς (pine wood), and that the statue made by
Dædalus was in wood; and then he immediately
turns around, and thinks that it proves the existence
of casting in plaster. It cannot mean both;
and the probability would seem to be that he is
wrong in both suppositions, and that Dædalus was
only employed in painting his statue in resin or wax.
The seriousness of this passage is more remarkable
than its accuracy. Who can the eminent and
learned artist be who has given us this so precious
information?—“ce renseignement tres-précieux,”—which
is known to every humble caster in
Europe,—though he is not quite correct in the
composition of what he says the Italians call
“ciment.” He must be a French artist who scorns
the Italian language as being, in the words of another
of his countrymen, “rien que de mauvais
Français.” “Ciment” is not an Italian word, and
“cimento” has a quite different significance,—that
of attempt or essay. The Italian casters call
this material “cera,” though it is not wax. But
aside from this, let us consider this passage from
Lucian to which Mr. Perkins, following other writers,
refers us as showing that the process of casting
in plaster was known to the ancient Greeks.
The Ζεὺς Τραγῳδός of Lucian is a satire on the
divinities of Greece, and a council of them is called
to deliberate on what should be done in consequence
of an assault upon their nature and power
by Damis. The gods are called upon, and a question
arises as to the precedence they should have,
whether it should be according to the material of
which they are made,—of ivory, gold, bronze,
stone, or clay,—or according to the excellence of
their workmanship and the skill of the artist; but
such confusion of claims is made that no precedence
is finally allowed to any one, and the question
as to the reasons and arguments of Damis
and his opponent Timocles is discussed. While
this is going on, a figure is seen approaching which
is thus described:—
“But who is this who comes in such haste
[ὁ χαλκοῦς, ὁ εὔγραμμος, ὁ εὐπερίγραφος, ὁ ἀρχαῖος τὴν
ἀνάδεσιν τῆς κόμης], this bronze, this beautifully
chased or engraved, beautifully outlined, the archaic
in the arrangement of his hair [πίττης γοῦν
ἀναπέπλησαι, ὁσημέραι ἐκματτόμενος ὑπὸ τῶν ἀνδριαντοποιῶν];
he is clogged with pitch from seals
or impressions being daily taken from it by the
sculptors.”
Hermes, the bronze, then answers:—
“It happened lately that my breast and back
were covered with pitch by the sculptors in bronze,
and a ridiculous cuirass was thus formed on my
body, and by imitative art received a complete seal
from the brass.”24
This passage is supposed to indicate the process
of casting in plaster. It is possible that it may
indicate a preparation in pitch to cast in bronze,
but certainly not in plaster, which is the sole question.
It is not workers in plaster who are engaged
on it, but workers in bronze; and what they
were doing was plainly to take impressions of the
intaglio chasing or engraving on the body of the
figure. The description of the bronze is that it
was archaic, and beautifully traced and engraved.
It may have been a term engraved with verses,
or figures, or inscriptions; and this is by no means
improbable, as it represented Hermes, and as
nothing but the breast and back was covered with
pitch. At all events, the process was one which
seems to have been carried on, not for once, but
daily. It may have been the famous Hermes
ἀγοραῖος, which was cast in the 34th Olympiad,
and was a study for brass casters. Again, it
may not have been a figure in the round, but
merely a bas-relief, or intaglio; and this supposition
would be entirely in accordance with the
hieratic and archaic sculpture in brass, marble,
and terra cotta. Many were executed thus in intaglio
and engraved,—some of which still remain,—and
others in relief. A list of such may be
found in Müller’s “Ancient Art” (pp. 61–65). If
the passage refers to making a mould for casting,
it was for casting in bronze and not in plaster,
though nothing is said about casting, but merely of
taking impressions or seals. The words ἐκτυπούμενος
and ἐκματτόμενος mean ex-pressions from a seal or
stamp. Exactly what the sculptors were doing,
however, to this statue covers the process of brass
casters. Thus Lucian, speaking of a certain brass
statue in the Agora, says: οἶσθα τὸν χαλκοῦν τὸν
ἑσῶτα ἐν τῇ ἀγορᾷ, καὶ τὰ μὲν πιττῶν τὰ δὲ εὔων διετέλεσα,—“You
know the brass statue standing in the
forum, on which I was occupied pitching and drying,”
or burning.
But there is nothing new in all this, and nothing
which throws any light upon the subject in question.
It was, as we well know, a common practice
of the Greeks, in making their large statues, to
build up a core of wood, brickwork, plaster, and
other materials as a foundation or rough sketch.
On the surface of this in their chryselephantine
statues they veneered sheets of gold and ivory,
sometimes covering the entire surface with these
precious materials, and sometimes finishing portions
of them with an exterior of plaster or clay,
which was painted in imitation of life. This for
instance was the case with the Dionysos in Kreusis,
described by Pausanias, of which the whole figure
was modeled in plaster and afterwards colored.
It would also seem to have been a practice with
the Greek artists to cover these roughly executed
cores with a composition of resin and pitch which
they indurated by fire; and afterwards to finish
the surface in the same material. Such at least
appears to be the process indicated by Lucian
in the passage just quoted, in which he speaks of
the statue he was engaged in pitching and drying;
as well as by Apollodorus in a passage in
which Dædalus is described as making a statue
of Hercules in pitch (πίσσα). The term “pissa”
in this last passage has by some translators been
supposed to be a misprint for ἐν πίση, meaning
that this statue was a ζόανον executed in pine
wood like other Dædalian figures. As it stands
in the original, certainly, it is πίσσα, and means
pitch; and it is quite as probable that it is correct
and means a sort of encaustic finish with resin and
gum. However this may be, there is little doubt
that in making their bronze statues the Greeks
used a surface of wax and pitch, or some such material,
which was plastic and would melt; and it is
well known that they spread wax over their statues
to give them a polished surface, and also finished
their plaster walls with a covering of wax.
In making large statues, a skeleton framework
of wood was often employed, called κίνναβος, or
κάναβος, which was covered with solid material,—clay,
plaster, brick, pitch, etc., all welded together
to form a solid core over which the surface was
finished in clay, plaster, pitch, ivory, or gold. In
the “Somnium, seu Gallus” of Lucian, Gallus
says, speaking of himself, “If he were king, he
should be like one of the colossi of Phidias,
Praxiteles, or Myron, which though externally
like Neptune or Jupiter,—splendid with ivory
and gold, bearing the trident or the thunderbolt,—yet
if you look inside you will find them composed
of beams and bolts and nails traversing
them everywhere, and braces and ridges, and pitch
and clay, and other ugly and misshapen things.”
It is a curious fact bearing generally on this
subject that no allusion is ever made to such a
person as a caster in plaster. Plutarch, enumerating
the various trades and occupations to which
the great public works of his time gave employment,
speaks of operatives, modelers, brass-workers,
stone-workers, gold and ivory workers, weavers,
and engravers, but never mentions a caster. Philostratus
also, enumerating the different classes of
workmen in the plastic art, makes no mention of
casters. Pliny never speaks of them. Indeed,
their existence is never mentioned by any ancient
writer.
All things considered, then, in conclusion, it
seems impossible to believe that Pliny intended,
in the passage relating to Lysistratus, to declare
that he invented any method of casting in plaster,
but rather that he intended to say that Lysistratus
either modeled likenesses in wax over a core of
gypsum, or, what is much more probable, that he
colored his likenesses in imitation of life; and
that his specialty was making accurate and literal
likenesses in the round with color, thus uniting
the two arts of the painter and the sculptor.
The process of casting in plaster, in our acceptation
of the phrase, is of modern origin, and so
far as we know was invented in the fifteenth century,
a little before the time of Verrocchio (1432–1488),
the master of Leonardo da Vinci. He was among
the first who employed it, and may fairly be said
to have introduced it. At all events, the first
clear mention of this process of which we are
aware is by Vasari in his life of Verrocchio; and
he states that this sculptor and painter “cast
hands, knees, feet, legs, even torsi, in order to
copy them at his leisure; and that soon after
casts began to be made from the faces of persons
after death, so that one sees in every house in
Florence, on mantel-pieces, doors, windows, and
cornices, a great number of these portraits, which
seem alive.” For some time after it seems to
have been used chiefly for taking casts from dead
faces,—or hands and feet,—and not to have
been applied to casting from models of clay. The
general practice of that period was to make a
small model in clay, then to bake it, and from this
model by proportional compasses to enlarge it
and point it upon the marble. The process of
casting from clay models seems not to have been
practiced then, and so far as we know models of
full size in clay were rarely if ever made, until
rather a comparatively recent period.
