an Aeduan noble, and brother of Dumnorix, is mentioned by Cicero ( de Div. 1.41) as belonging to the order of Druids, and professing much knowledge of the secrets of nature and of divination. He was a warm adherent of the Romans and of Caesar, who, in consideration of his earnest entreaties, pardoned the treason of Dumnorix in B. C. 58. In the same year he took the most proninent part among the Gallic chiefs in requesting Caesar's aid against Ariovistus [see p. 287]; he had, some time before, gone even to Rome to ask the senate for their interference, but without success. It was probably during this visit that he was the guest of Cicero (de Div l.c.). Throughout, Caesar placed the greatest confidence in him, and in B. C. 57, pardoned, at his intercession, the Bellovaci, who had joined with the rest of the Belgians in their conspiracy. (Caes. Gal. 1.3, 16_20, 31, 32, 2.5, 14, 15. 6.12, 7.39; Plut. Caes. 19; D. C. 38.34, &c.)
