Gallic War (6.12-6.16)

When Caesar arrived in Gaul, the Aedui were the leaders of one faction, the Sequani of the other. Since the latter were less powerful by themselves, inasmuch as the chief influence was from of old among the Aedui, and their dependencies were great, they had united to themselves the Germans and Ariovistus, and had brought them over to their party by great sacrifices and promises. And having fought several successful battles and slain all the nobility of the Aedui, they had so far surpassed them in power, that they brought over, from the Aedui to themselves, a large portion of their dependents and received from them the sons of their leading men as hostages, and compelled them to swear in their public character that they would enter into no design against them; and held a portion of the neighboring land, seized on by force, and possessed the sovereignty of the whole of Gaul. Divitiacus urged by this necessity, had proceeded to Rome to the senate, for the purpose of entreating assistance, and had returned without accomplishing his object. A change of affairs ensued on the arrival of Caesar, the hostages were returned to the Aedui, their old dependencies restored, and new acquired through Caesar (because those who had attached themselves to their alliance saw that they enjoyed a better state and a milder government), their other interests, their influence, their reputation were likewise increased, and in consequence, the Sequani lost the sovereignty. The Remi succeeded to their place, and, as it was perceived that they equaled the Aedui in favor with Caesar, those, who on account of their old animosities could by no means coalesce with the Aedui, consigned themselves in clientship to the Remi. The latter carefully protected them. Thus they possessed both a new and suddenly acquired influence. Affairs were then in that position that the Aedui were considered by far the leading people, and the Remi held the second post of honor.

Throughout all Gaul there are two orders of those men who are of any rank and dignity: for the commonality is held almost in the condition of slaves, and dares to undertake nothing of itself, and is admitted to no deliberation. The greater part, when they are pressed either by debt, or the large amount of their tributes, or the oppression of the more powerful, give themselves up in vassalage to the nobles, who possess over them the same rights without exception as masters over their slaves. But of these two orders, one is that of the Druids, the other that of the knights. The former are engaged in things sacred, conduct the public and the private sacrifices, and interpret all matters of religion. To these a large number of the young men resort for the purpose of instruction, and they [the Druids] are in great honor among them. For they determine respecting almost all controversies, public and private; and if any crime has been perpetrated, if murder has been committed, if there be any dispute about an inheritance, if any about boundaries, these same persons decide it; they decree rewards and punishments; if any one, either in a private or public capacity, has not submitted to their decision, they interdict him from the sacrifices. This among them is the most heavy punishment. Those who have been thus interdicted are esteemed in the number of the impious and the criminal: all shun them, and avoid their society and conversation, lest they receive some evil from their contact; nor is justice administered to them when seeking it, nor is any dignity bestowed on them. Over all these Druids one presides, who possesses supreme authority among them. Upon his death, if any individual among the rest is pre-eminent in dignity, he succeeds; but, if there are many equal, the election is made by the suffrages of the Druids; sometimes they even contend for the presidency with arms. These assemble at a fixed period of the year in a consecrated place in the territories of the Carnutes, which is reckoned the central region of the whole of Gaul. Hither all, who have disputes, assemble from every part, and submit to their decrees and determinations. This institution is supposed to have been devised in Britain, and to have been brought over from it into Gaul; and now those who desire to gain a more accurate knowledge of that system generally proceed thither for the purpose of studying it.

The Druids do not go to war, nor pay tribute together with the rest; they have an exemption from military service and a dispensation in all matters. Induced by such great advantages, many embrace this profession of their own accord, and [many] are sent to it by their parents and relations. They are said there to learn by heart a great number of verses; accordingly some remain in the course of training twenty years. Nor do they regard it lawful to commit these to writing, though in almost all other matters, in their public and private transactions, they use Greek characters. That practice they seem to me to have adopted for two reasons; because they neither desire their doctrines to be divulged among the mass of the people, nor those who learn, to devote themselves the less to the efforts of memory, relying on writing; since it generally occurs to most men, that, in their dependence on writing, they relax their diligence in learning thoroughly, and their employment of the memory. They wish to inculcate this as one of their leading tenets, that souls do not become extinct, but pass after death from one body to another, and they think that men by this tenet are in a great degree excited to valor, the fear of death being disregarded. They likewise discuss and impart to the youth many things respecting the stars and their motion, respecting the extent of the world and of our earth, respecting the nature of things, respecting the power and the majesty of the immortal gods.

The other order is that of the knights. These, when there is occasion and any war occurs (which before Caesar's arrival was for the most part wont to happen every year, as either they on their part were inflecting injuries or repelling those which others inflected on them), are all engaged in war. And those of them most distinguished by birth and resources, have the greatest number of vassals and dependents about them. They acknowledge this sort of influence and power only.

The nation of all the Gauls is extremely devoted to superstitious rites; and on that account they who are troubled with unusually severe diseases, and they who are engaged in battles and dangers, either sacrifice men as victims, or vow that they will sacrifice them, and employ the Druids as the performers of those sacrifices; because they think that unless the life of a man be offered for the life of a man, the mind of the immortal gods can not be rendered propitious, and they have sacrifices of that kind ordained for national purposes. Others have figures of vast size, the limbs of which formed of osiers they fill with living men, which being set on fire, the men perish enveloped in the flames. They consider that the oblation of such as have been taken in theft, or in robbery, or any other offense, is more acceptable to the immortal gods; but when a supply of that class is wanting, they have recourse to the oblation of even the innocent.
