In B.C. 64 Cicero attained his chief ambition by being elected to the consulship, but we have little trace of his public actions that year, only the fragments of one speech remaining, in defence of Q. Gallius on a charge of ambitus. The animus of the popular party, however, is shown by the prosecution of some surviving partisans of Sulla on charges of homicide, among them Catiline, who by some means escaped conviction (Dio, 37.10).
