Gaius Sosius
'Gaius Sosius', was a Roman general and politician.
Gaius Sosius was elected
quaestor in
66 BC and
praetor in
49 BC. Upon the start of the
civil war he joined the
optimates. Upon the flight of
Pompey to Greece, Sosius returned to Rome and submitted to
Julius Caesar
After the assassination of Caesar, Sosius joined the party of
Mark Antony, by whom in
38 BC he was appointed governor of Syria and
Cilicia in the place of
Publius Ventidius. As governor, Sosius was commanded by Antony to support
Herod against
Antigonus the Hasmonean, when the latter was in possession of
Jerusalem. In
37 BC he advanced against Jerusalem and after he became master of the city, Sosius placed Herod upon the throne.
In return for this services, he was awarded a triumph in
34 BC, and he became
consul along with
Gnaeus Domitius Ahenobarbus as his colleague in
32 BC. When
civil war broke out between Anthony and
Octavian, Sosius espoused the cause of Anthony and violently attacked Octavian in the senate, for which he was forced to flee to the east. In
31 BC, Sosius commanded a squadron in Mark Anthony's fleet with which he managed to defeat the squadron of
Lucius Arruntius and put it to flight, but when the latter was reinforced by
Marcus Agrippa, Sosius's ally
Tarcondimotus - the king of Cilicia - was killed and Sosius himself was forced to flee. In the
battle of Actium, Sosius commanded the left wing of the fleet. After the battle, from which he managed to escape, his hiding place was detected and Sosius was captured and brought before Octavian but at the intercession of Lucius Arruntius Octavian pardoned him. He returned to Rome and completed his building project on the
temple of Apollo Medicus (begun in
34 BC), dedicating it in Octavian's name.
