Caius Octavius came to Rome from Epirus, whither Cæsar had sent him to conduct the war in Macedonia; and, having received favourable omens, assumed the name of Cæsar. In the confusion and bustle of affairs, Lepidus procured the office of chief priest. But when Marcus Antonius, the consul, governed with violence, and forcibly caused a law to be passed respecting the change of provinces; and had also given very injurious treatment to Cæsar, when he requested that he would assist him in punishing the murderers of his uncle; Cæsar, to strengthen himself and the commonwealth against him, called out the veteran soldiers, who had been settled in the colonies. The fourth and Martian legions also deserted from Antony to Cæsar. Afterwards also very many revolted to Caasar, on account of the cruelty of Antony, who slaughtered every where in their own camps even those whom he suspected. Decimus Brutus, in order to stop Antonius on his way into Cisalpine Gaul, seized Mutina with his army. This book contains also the history of the attempts of both parties to possess themselves of the provinces, and of the preparations for war.
