Publius Cornelius, one of Caesar's generals and the son-in-law of Cicero, was born about B.C. 70. At the death of Caesar he espoused the party of Brutus, but soon after went over to that of the Triumvir. By them he was intrusted with the province of Syria and the command against the Parthians; and accordingly he proceeded to Asia Minor, where he abused his power for the purpose of extorting money and troops from the inhabitants. For this he was declared an enemy of his country; and Cassius, to whom the proconsulate of Syria had been handed over, declared war against him. After the fall of Laodicea, Dolabella in despair ordered one of his soldiers to kill him, B.C. 43.
