The Parthians, who had joined the Pompeian party, under the command of Labienus, invaded Syria, and having beaten Decidius Saxa, a lieutenant-general under Antonius, seized that whole province. When Marcus Antonius was excited to dispute with Cæsar by his wife Fulvia, having dismissed her, lest she should mar the concord of the generals, and having concluded a treaty of peace with Cæsar, he married his sister Octavia. He himself informed against Quintus Salvidienus, who was forming a villanous combination against Cæsar, who, having been condemned, committed suicide. [y. r. 713. b. c. 39.] Publius Ventidius, the lieutenant of Antony, drove the Parthians from Syria, having conquered them in battle, their general, Labienus, having been slain. When Sextus Pompey held Sicily, (being hostilely disposed, and near to Italy,) and obstructed the commerce in corn, at his own request Cæsar and Antony entered into a treaty of peace, so that he was made governor of Sicily.
