6. P.Antistius, tribune of the plebs, B. C. 88, opposed in his tribuneship C. Caesar Strabo, who was a candidate for the consulship without having been praetor. The speech he made upon this occasion brought him into public notice, and afterwards he frequently had important causes entrusted to him, though he was already advanced in years. Cicero speaks favourably of his eloquence. In consequence of the marriage of his daughter to Pompeius Magnus, he supported the party of Sulla, and was put to death by order of young Marius in B. C. 82. His wife Calpurnia killed herself upon the death of her husband. (Cic. Brut. 63, 90, pro Rosc. Amer. 32; Vell. 2.26; Appian, App. BC 1.88; Liv. Epit. 86; Plut. Pomp. 9; Drumann, Gesch. Roms, i. p. 55.)
