the person who managed the affairs of M. Antonius, in Italy, was one of the chief instigators of the war in B. C. 42, usually known as the Perusinian war, which was carried on by L. Antonius and Fulvia, the wife of the triumvir, against Octavianus, during the absence of M. Antonius in the East. Manius also took an active part in the conduct of the war, but he was destined to pay dearly for his activity: for upon the reconciliation of Antonius and Octavianus, in B. C. 40, Manius was put to death by the former, as one of the disturbers of the peace, but partly, it appears, on account of his having exasperated Fulvia against Antonius.
