There in like manner, Vercingetorix the son of Celtillus the Arvernian, a young man of the highest power (whose father had held the supremacy of entire Gaul, and had been put to death by his fellow-citizens, for this reason, because he aimed at sovereign power), summoned together his dependents, and easily excited them. On his design being made known, they rush to arms: he is expelled from the town of Gergovia, by his uncle Gobanitio and the rest of the nobles, who were of opinion, that such an enterprise ought not to be hazarded: he did not however desist, but held in the country a levy of the needy and desperate. Having collected such a body of troops, he brings over to his sentiments such of his fellow-citizens as he has access to: he exhorts them to take up arms in behalf of the general freedom, and having assembled great forces he drives from the state his opponents, by whom he had been expelled a short time previously. He is saluted king by his partisans; he sends embassadors in every direction, he conjures them to adhere firmly to their promise. He quickly attaches to his interests the Senones, Parisii, Pictones, Cadurci, Turones, Aulerci, Lemovice, and all the others who border on the ocean; the supreme command is conferred on him by unanimous consent. On obtaining this authority, he demands hostages from all these states, he orders a fixed number of soldiers to be sent to him immediately; he determines what quantity of arms each state shall prepare at home, and before what time; he pays particular attention to the cavalry. To the utmost vigilance he adds the utmost rigor of authority; and by the severity of his punishments brings over the wavering: for on the commission of a greater crime he puts the perpetrators to death by fire and every sort of tortures; for a slighter cause, he sends home the offenders with their ears cut off, or one of their eyes put out, that they may be an example to the rest, and frighten others by the severity of their punishment.
