tribune of the plebs, A. D. 58, murdered his mistress, Pontia Postumia, because she had refused to marry him after promising to do so. He was accused by the father of Pontia, and condemned to deportatio in insulam. In the civil wars which followed Nero's death he returned to Rome, but was again condemned by the senate to his former punishment, A. D. 70. (Tac. Ann. 13.44, Hist. 4.44.)
