GNAEUS DOMITIUS AHENOBARBUS, son of the above, accom panied by his father at Corfinium and Pharsalus, and, having been pardoned by Caesar, returned to Rome in 46 B.C. After Caesar's assassination he attached himself to Brutus and Cassius, and in 43 B.C. was condemned by the lex Pedia as having been impli cated in the plot. He obtained considerable naval successes in the Ionian Sea against the triumvirate, both before and after Philippi, but in 4o B.C. became reconciled to Antony, who made him gov ernor of Bithynia. He took part in Antony's Parthian cam paigns, and was consul in 32 B.C. When war broke out between Antony and Octavian, he at first supported Antony, but, disgusted with his intrigue with Cleopatra, went over to Octavian shortly before the battle of Actium (31 B.c.). He died soon afterwards (Dio Cassius xlviii.-1. ; Appian, Bell. Civ., iv., v.). His son was married to Antonia, daughter of Antony, and became the grand father of the emperor Nero.
