No name in connection with Celtic religion is more familiar to the
average reader than that of the Druids, yet there is no section of the
history of Celtic religion that has given rise to greater discussion
than that relating to this order. Even the association of the
name with the Indo-European root dru-, which we find in the Greek
word drus, an oak, has been questioned by such a competent Celtic
scholar as M. d’Arbois de Jubainville, but on this point it cannot
be said that his criticism is conclusive. The writers of the ancient
world who refer to the Druids, do not always make it sufficiently clear
in what districts the rites, ceremonies, and functions which they were
describing prevailed. Nor was it so much the priestly character
of the Druids that produced the deepest impression on the ancients.
To some philosophical and theological writers of antiquity their doctrines
and their apparent affinities with Pythagoreanism
were of much greater interest than their ceremonial or other functions.
One thing at any rate is clear, that the Druids and their doctrines,
or supposed doctrines, had made a deep impression on the writers of
the ancient world. There is a reference to them in a fragment
of Aristotle (which may not, however, be genuine) that is of interest
as assigning them a place in express terms both among the Celts and
the Galatæ. The prominent feature of their teaching which
had attracted the attention of other writers, such as the historian
Diodorus Siculus and the Christian theologian Clement of Alexandria,
was the resemblance of their doctrine concerning the immortality and
transmigration of the soul to the views of Pythagoras. Ancient
writers, however, did not always remember that a religious or philosophical
doctrine must not be treated as a thing apart, but must be interpreted
in its whole context in relation to its development in history and in
the social life of the community in which it has flourished. To
some of the ancients the superficial resemblance between the Druidic
doctrine of the soul’s future and the teaching attributed to Pythagoras
was the essential point, and this was enough to give the Druids a reputation
for philosophy, so that a
writer like Clement of Alexandria goes so far as to regard the Druids
of the ‘Galatæ’ along with the prophets of the Egyptians,
the ‘Chaldæans’ of the Assyrians, the ‘philosophers
of the Celts,’ and the Magi of the Persians as the pioneers of
philosophy among the barbarians before it spread to the Greeks.
The reason for the distinction drawn in this passage between the ‘Druids
of the Galatæ’ and ‘the philosophers of the Celts’
is not clear. Diodorus Siculus calls attention to the Druidic
doctrine that the souls of men were immortal, and that after the lapse
of an appointed number of years they came to life again, the soul then
entering into another body. He says that there were certain ‘philosophers
and theologians’ that were called Druids who were held in exceptional
honour. In addition to these, the Celts, he says, had also seers,
who foretold the future from the flight of birds and by means of the
offering of sacrifices. According to him it was these priestly
seers who had the masses in subjection to them. In great affairs
they had, he says, the practice of divination by the slaughter of a
human victim, and the observation of the attitude in which he fell,
the contortions of the limbs, the spurting of the blood, and the like.
This, he states, was an ancient and established practice.
Moreover, it was the custom, according to Diodorus, to make no sacrifice
without the presence of a philosopher (apparently a Druid in addition
to the sacrificing seer), the theory being that those who were authorities
on the divine nature were to the gods intelligible mediators for the
offering of gifts and the presentation of petitions. These philosophers
were in great request, together with their poets, in war as well as
in peace, and were consulted not merely by the men of their own side,
but also by those of the enemy. Even when two armies were on the
point of joining battle, these philosophers had been able, Diodorus
says, to step into the space between them and to stop them from fighting,
exactly as if they had charmed wild beasts. The moral which Diodorus
draws from this is, that even among the wildest of barbarians the spirited
principle of the soul yields to wisdom, and that Ares (the god of war)
even there respects the Muses. It is clear from this account that
Diodorus had in mind the three classes of non-military professional
men among the Celts, to whom other ancient writers also refer, namely,
the Bards, the Seers, and the Druids. His narrative is apparently
an expansion, in the light of his reading and philosophical meditation,
of information supplied by
previous writers, notably Posidonius. The latter, too, appears
to have been Julius Cæsar’s chief authority, in addition
to his own observation, but Cæsar does not appear expressly to
indicate the triple division here in question. The account which
he gives is important, and would be even more valuable than it is had
he told us how far what he describes was written from his own personal
information, and the degree of variation (if any) of religious practice
in different districts. However, Cæsar’s statements
deserve the closest consideration. After calling attention to
the division of the Gaulish aristocracy into two main sections, the
Druids and the Knights, he proceeds to speak of the Druids. These
were occupied, he says, with religious matters, they attended to public
and private sacrifices, and interpreted omens. Moreover, they
were the teachers of the country. To them the young men congregated
for knowledge, and the pupils held their teachers in great respect.
They, too, were the judges in public and private disputes: it was they
who awarded damages and penalties. Any contumacy in reference
to their judgments was punished by exclusion from the sacrifices.
This sentence of excommunication was the severest punishment among the
Gauls. The men so punished were treated as outlaws, and cut
off from all human society, with its rights and privileges. Over
these Druids there was one head, who wielded the highest influence among
them. On his death the nearest of the others in dignity succeeded
him, or, if several were equal, the election of a successor was made
by the vote of the Druids. Sometimes the primacy was not decided
without the arbitrament of arms. The Druids met at a fixed time
of the year in a consecrated spot in the territory of the Carnutes,
the district which was regarded as being in the centre of the whole
of Gaul. This assembly of Druids formed a court for the decision
of cases brought to them from everywhere around. It was thought,
Cæsar says, that the doctrine of the Druids was discovered in
Britain and thence carried over into Gaul. At that time, too,
those who wanted to make a profounder study of it resorted thither for
their training. The Druids had immunity from military service
and from the payment of tribute. These privileges drew many into
training for the profession, some of their own accord, others at the
instance of parents and relatives. While in training they were
said to learn by heart a large number of verses, and some went so far
as to spend twenty years in their course of preparation. The Druids
held it wrong to put their religious
teaching in writing, though, in almost everything else, whether public
or private affairs, they made use of Greek letters. Cæsar
thought that they discouraged writing on the one hand, lest their teaching
should become public property; on the other, lest reliance upon writing
should lessen the cultivation of the memory. To this risk Cæsar
could testify from his own knowledge. Their cardinal doctrine
was that souls did not perish, but that after death they passed from
one person to another; and this they regarded as a supreme incentive
to valour, since, with the prospect of immortality, the fear of death
counted for nothing. They carried on, moreover, many discussions
about the stars and their motion, the greatness of the universe and
the lands, the nature of things, the strength and power of the immortal
gods, and communicated their knowledge to their pupils. In another
passage Cæsar says that the Gauls as a people were extremely devoted
to religious ideas and practices. Men who were seriously ill,
who were engaged in war, or who stood in any peril, offered, or promised
to offer, human sacrifices, and made use of the Druids as their agents
for such sacrifices. Their theory was, that the immortal gods
could not be appeased unless a human life were given for a human
life. In addition to these private sacrifices, they had also similar
human sacrifices of a public character. Cæsar further contrasts
the Germans with the Gauls, saying that the former had no Druids to
preside over matters of religion, and that they paid no attention to
sacrifices.
In his work on divination, Cicero, too, refers to the profession
which the Druids made of natural science, and of the power of foretelling
the future, and instances the case of the Æduan Divĭciācus,
his brother’s guest and friend. Nothing is here said by
Cicero of the three classes implied in Diodorus, but Timagenes (quoted
in Ammianus) refers to the three classes under the names ‘bardi,’
‘euhages’ (a mistake for ‘vates’), and ‘drasidæ’
(a mistake for ‘druidæ’). The study of nature
and of the heavens is here attributed to the second class of seers (vates).
The highest class, that of the Druids, were, he says, in accordance
with the rule of Pythagoras, closely linked together in confraternities,
and by acquiring a certain loftiness of mind from their investigations
into things that were hidden and exalted, they despised human affairs
and declared the soul immortal. We see here the view expressed
that socially as well as intellectually the Druids lived according to
the Pythagorean philosophy. Origen also
refers to the view that was prevalent in his time, that Zamolxis, the
servant of Pythagoras, had taught the Druids the philosophy of Pythagoras.
He further states that the Druids practised sorcery. The triple
division of the non-military aristocracy is perhaps best given by Strabo,
the Greek geographer, who here follows Posidonius. The three classes
are the Bards, the Seers (ouateis=vates), and Druids. The Bards
were hymn-writers and poets, the Seers sacrificers and men of science,
while the Druids, in addition to natural science, practised also moral
philosophy. They were regarded as the justest of men, and on this
account were intrusted with the settlement of private and public disputes.
They had been the means of preventing armies from fighting when on the
very verge of battle, and were especially intrusted with the judgment
of cases involving human life. According to Strabo, they and their
fellow-countrymen held that souls and the universe were immortal, but
that fire and water would sometime prevail. Sacrifices were never
made, Strabo says, without the intervention of the Druids. Pomponius
Mela says that in his time (c. 44 a.d.),
though the ancient savagery was no more, and the Gauls abstained from
human sacrifices, some traces of their former practices still
remained, notably in their habit of cutting a portion of the flesh of
those condemned to death after bringing them to the altars. The
Gauls, he says, in spite of their traces of barbarism, had an eloquence
of their own, and had the Druids as their teachers in philosophy.
These professed to know the size and form of the earth and of the universe,
the motions of the sky and stars, and the will of the gods. He
refers, as Cæsar does, to their work in education, and says that
it was carried on in caves or in secluded groves. Mela speaks
of their doctrine of immortality, but says nothing as to the entry of
souls into other bodies. As a proof of this belief he speaks of
the practice of burning and burying with the dead things appropriate
to the needs of the living. Lucan, the Latin poet, in his Pharsalia,
refers to the seclusion of the Druids’ groves and to their doctrine
of immortality. The Scholiasts’ notes on this passage are
after the manner of their kind, and add very little to our knowledge.
In Pliny’s Natural History (xvi, 249), however, we seem
to be face to face with another, though perhaps a distorted, tradition.
Pliny was an indefatigable compiler, and appears partly by reading,
partly by personal observation, to have noticed phases of Celtic religious
practices which other writers had overlooked. In the first place
he calls attention to the veneration in which the Gauls held the mistletoe
and the tree on which it grew, provided that that tree was the oak.
Hence their predilection for oak groves and their requirement of oak
leaves for all religious rites. Pliny here remarks on the consonance
of this practice with the etymology of the name Druid as interpreted
even through Greek (the Greek for an oak being drūs).
Were not this respect for the oak and for the mistletoe paralleled by
numerous examples of tree and plant-worship given by Dr. Frazer and
others, it might well have been suspected that Pliny was here quoting
some writer who had tried to argue from the etymology of the name Druid.
Another suspicious circumstance in Pliny’s account is his reference
to the serpent’s egg composed of snakes rolled together into a
ball. He states that he himself had seen such an ‘egg,’
of about the size of an apple. Pliny, too, states that Tiberius
Cæsar abolished by a decree of the Senate the Druids and the kind
of seers and physicians the Gauls then had. This statement, when
read in its context, probably refers to the prohibition of human sacrifices.
The historian Suetonius, in his account of
the Emperor Claudius, also states that Augustus had prohibited ‘the
religion of the Druids’ (which, he says, ‘was one of fearful
savagery’) to Roman citizens, but that Claudius had entirely abolished
it. What is here also meant, in view of the description given
of Druidism, is doubtless the abolishing of its human sacrifices.
In later Latin writers there are several references to Druidesses, but
these were probably only sorceresses. In Irish the name drúi
(genitive druad) meant a magician, and the word derwydd
in mediæval Welsh was especially used in reference to the vaticinations
which were then popular in Wales.
When we analyse the testimony of ancient writers concerning the Druids,
we see in the first place that to different minds the name connoted
different things. To Cæsar it is the general name for the
non-military professional class, whether priests, seers, teachers, lawyers,
or judges. To others the Druids are pre-eminently the philosophers
and teachers of the Gauls, and are distinguished from the seers designated
vates. To others again, such as Pliny, they were the priests
of the oak-ritual, whence their name was derived. In view of the
variety of grades of civilisation then co-existing in Gaul and Britain,
it is not improbable
that the development of the non-military professional class varied very
considerably in different districts, and that all the aspects of Druidism
which the ancient writers specify found their appropriate places in
the social system of the Celts. In Gaul and Britain, as elsewhere,
the office of the primitive tribal medicine-man was capable of indefinite
development, and all the forms of its evolution could not have proceeded
pari passu where the sociological conditions found such scope
for variation. It may well be that the oak and mistletoe ceremonies,
for example, lingered in remote agricultural districts long after they
had ceased to interest men along the main routes of Celtic civilisation.
The bucolic mind does not readily abandon the practices of millennia.
In addition to the term Druid, we find in Aulus Hirtius’ continuation
of Cæsar’s Gallic War (Bk. viii., c. xxxviii., 2),
as well as on two inscriptions, one at Le-Puy-en-Velay (Dep. Haute-Loire),
and the other at Mâcon (Dep. Saône-et-Loire), another priestly
title, ‘gutuater.’ At Mâcon the office is that
of a ‘gutuater Martis,’ but of its special features nothing
is known.
