The next year peace was effected with Sextus, a son of the great Pompey, who had been proscribed as one of the murderers of Cæsar, though he had really had no share in that deed. He had been engaged in marauding expeditions having for their purpose the injury of the triumvirs, and at this time had been able to cut off a considerable share of the supply of grain from Sicily and Africa. He was indemnified for the loss of his private property and was given an important command for five years. This agreement was never consummated, for Antony had not been consulted and refused to carry out a portion of it that depended upon him. Again Pompey entered upon his marauding expeditions, and the price of grain rose rapidly at Rome. Two years were occupied in preparing a fleet, which was placed under command of Agrippa, who defeated Pompey off Naulochus, on the northwestern coast of Sicily (Sept. 3, 36.) In the midst of the preparations for the war with Pompey, (B.C. 37) discord had arisen between Antony and Octavius, and the commander of the Eastern army set out for Italy with a fleet of three hundred sail. Octavius forbade his landing, and he kept on his course to Tarentum, where a conference was held. There were present on this memorable occasion, besides the two triumvirs, Agrippa, the great general; Octavia, sister of one triumvir and wife of the other, one of the noblest women of antiquity; and Caius Cilnius Mæcenas, a wealthy patron of letters, who had also been present when the negotiations were made previous to the peace of Brundusium, three years before. Probably the satiric poet Horace was also one of the group, for he gives, in one of his satires, an account of a journey from Rome to Brundusium, which he is supposed to have made at the time that Mæcenas was hurrying to the conference. Horace says that he set out from Rome accompanied by Heliodorus, a rhetorician whom he calls by far the most learned of the Greeks, and that they found a middling inn at Aricia, the first stopping-place, on the Appian Way, sixteen miles out, at the foot of the Alban mount.
