High Quality Content by WIKIPEDIA articles! Gnaeus Domitius Calvinus was a Roman general, senator and consul (both in 53 BC and 40 BC) who was a loyal partisan of Caesar and Octavianus. Domitius Calvinus came from a noble family and was elected consul in 53 BC, despite a notorious electoral scandal. He was on Caesar s side during the Civil War with Pompey. At the decisive battle of Pharsalus he commanded the center of Caesar s army. After the battle he became governor of Asia. He tried to oppose the invasion of Pharnaces, the king of Bosphorus, who had taken the occasion of the Roman civil war to invade the province of Pontus; however he suffered a crushing defeat at the battle of Nicopolis in Armenia (December of 48 BC). Direct intervention by Caesar brought a quick end to the conflict, and Pharnaces army was annihilated at Zela in 47 BC. Despite this failure, he remained a trusted friend of Caesar. Domitius Calvinus's activities after the death of Caesar are unknown, but in 43 BC he was a strong supporter of Octavianus and participated in the civil war against Brutus and Cassius..
