When the time came for him to set out for the war, he took a garland from the sacred olive, and, in obedience to some oracle, he filled a vessel with the water of the Clepsydra to carry along with him. In this interval, Pacorus, the Parthian king's son, who was marching into Syria with a large army, was met by Ventidius, who gave him battle in the country of Cyrrhestica, slew a large number of his men, and Pacorus among the first. This victory was one of the most renowned achievements of the Romans, and fully avenged their defeats under Crassus, the Parthians being obliged, after the loss of three battles successively, to keep themselves within the bounds of Media and Mesopotamia. Ventidius was not willing to push his good fortune further, for fear of raising some jealousy in Antony, but turning his aims against those that had quitted the Roman interest, he reduced them to their former obedience. Among the rest, he besieged Antiochus, King of Commagene, in the city of Samosata, who made an offer of a thousand talents for his pardon, and a promise of submission to Antony's commands. But Ventidius told him that he must send to Antony, who was already on his march, and had sent word to Ventidius to make no terms with Antiochus, wishing that at any rate this one exploit might be ascribed to him, and that people might not think that all his successes were won by his lieutenants. The siege, however, was long protracted; for when those within found their offers refused, they defended themselves stoutly, till, at last, Antony, finding he was doing nothing, in shame and regret for having refused the first offer, was glad to make an accommodation with Antiochus for three hundred talents. And, having given some orders for the affairs of Syria, he returned to Athens; and, paying Ventidius the honours he well deserved, dismissed him to receive his triumph. He is the only man that has ever yet triumphed for victories obtained over the Parthians;he was of obscure birth, but, by means of Antony's friendship, obtained an opportunity of showing his capacity, and doing great things; and his making such glorious use of it gave new credit to the current observation about Caesar and Antony, that they were more fortunate in what they did by their lieutenants than in their own persons. For Sossius, also, had great success, and Canidius, whom he left in Armenia, defeated the people there, and also the kings of the Albanians and Iberians, and marched victorious as far as Caucasus, by which means the fame of Antony's arms had become great among the barbarous nations.
He, however, once more, upon some unfavourable stories, taking offence against Caesar, set sail with three hundred ships for Italy, and, being refused admittance to the port of Brundusium, made for Tarentum. There his wife Octavia, who came from Greece with him, obtained leave to visit her brother, she being then great with child, having already borne her husband a second daughter; and as she was on her way she met Caesar, with his two friends Agrippa and Maecenas, and, taking these two aside, with great entreaties and lamentations she told them, that of the most fortunate woman upon earth, she was in danger of becoming the most unhappy; for as yet every one's eyes were fixed upon her as the wife and sister of the two great commanders, but, if rash counsels should prevail, and war ensue, "I shall be miserable," said she, "without redress; for on what side soever victory falls, I shall be sure to be a loser." Caesar was overcome by these entreaties, and advanced in a peaceable temper to Tarentum, where those that were present beheld a most stately spectacle; a vast army the up by the shore, and as great a fleet in the harbour, all without the occurrence of friends, and other expressions of joy and kindness, passing from one armament to the other. Antony first entertained Caesar, this also being a concession on Caesar's part to his sister; and when at length an agreement was made between them, that Caesar should give Antony two of his legions to serve him in the Parthian war, and that Antony should in return leave with him a hundred armed galleys, Octavia further obtained of her husband, besides this, twenty light ships for her brother, and of her brother, a thousand foot for her husband. So, having parted good friends, Caesar went immediately to make war with Pompey to conquer Sicily. And Antony, leaving in Caesar's charge his wife and children, and his children by his former wife Fulvia, set sail for Asia.
