a chieftain of the Treviri, who endeavoured to persuade the Gauls to join in the revolt of Civilis and Classicus (A. D. 70) but was unsuccessful, on account of the opposition of Julius Auspex and the Remi; so that only the Treviri and Lingones rebelled. Valentinus acted as the leader of the Treviri, but took more pains to secure their fidelity by harangues than their success by warlike preparations. When Cerealis passed the Alps, Valentinus joined Tutor in the attempt to oppose him.
In his absence two legions, which had surrendered to Classicus at Novesium and Bonna some time before, and, after taking the oath to the empire of Gaul, had been marched to the city of Treviri, voluntarily took the oath to Vespasian, and on the return of Valentinus and Tutor after their defeat by Cerealis retired to the friendly state of the Mediomatrici. Valentinus and Tutor roused the Treviri anew to arms, and, in order to make them desperate, killed Herennius and Numisius, the legates of the above legions. Cerealis soon marched against them from Magontiacum, stormed the strong position of Valentinus at Rigodulum, and entered Treviri, where he harangued and pardoned the two legions just mentioned, as well as the Treviri and Lingones. Valentinus, who had been taken prisoner at Rigodulum, was sent into Italy, and was delivered up to Mucianus and Domitian, who were on their march to support Cerealis.
He was condemned to death, and while undergoing his sentence, when some one taunted him with the misfortunes of his country, he replied that he accepted death as a solace for them. (Tac. Hist. 4.69
