Longinus, Cassius
5. L. Cassius Longinus, Q. F. Q. N., son of No. 3, was praetor B. C. 111, and was sent to Numidia to bring Jugurtha to Rome, under promise of a safe conduct. Cassius also pledged his own word to Jugurtha for his security; and so high was the reputation of Cassius, that the Numidian king valued this as much as the public promise. In B. C. 107 he was consul with C. Marius, and received as his province Narbonese Gaul, in order to oppose the Cimbri and their allies; but in the course of the same year he was defeated and killed by the Tigurini in the territory of the Allobroges. (Sal. Jug. 32; Liv. Epit. 65; Oros. 5.15; Caes. Gal. 1.7; Tac. Germ. 37.)
