tribune of the plebs, B. C. 59. During Cicero's consulship Flavus seconded him in his measures against Catiline (Cic. pro Planc. 42), but in his tribunate he was a zealous supporter of all Caesar's acts and laws. (Cic. pro Sest. 53; Schol. Bob. in Sextian. p. 304, in Vatinian. p. 324, ed. Orelli.) This seems to have cost Flavus the aedileship. He was, however, praetor, B. C. 54, after at least one repulse. Flavus afterwards appears as quaestor, or special commissioner, at the trial of A. Gabinius (Cic. ad Q. Fr. 3.1.7), and at that of Cn. Plancius (Cic. pro Planc. 17). Cicero always speaks of Flavus as an honest and well-meaning, but mistaken man.
