60 There was a certain Lucius Cocceius, a friend of both, who had been sent, in company with Caecina, by Octavian, the previous summer, to Antony in Phoenicia, and had remained with Antony after Caecina returned. This Cocceius, seizing his opportunity, pretended that he had been sent for by Octavian for the purpose of a friendly greeting. When Antony allowed him to go he asked, by way of testing his disposition, whether Antony would like to write any letter to Octavian making use of himself as his messenger. Antony replied: "What can we write to each other, now that we are enemies, except mutual recrimination? I wrote letters in reply to his of some time ago, which I sent by the hand of Caecina. Take copies of those if you like." This he said by way of jest, but Cocceius would not yet allow him to call Octavian an enemy after his generous behaviour towards Lucius and Antony's other friends. But Antony replied: "He has shut me out of Brundusium and taken my provinces and the army of Calenus from me. He is kind only to my friends, and evidently not to keep them friendly, but to make them enemies to me by his benefactions." Cocceius, after hearing these complaints, did not care to irritate further a naturally passionate disposition, but proceeded to make his visit to Octavian.

61 When Octavian saw him he expressed astonishment that he had not come sooner. "I did not save your brother," he exclaimed, "in order that you should be my enemy."​ Cocceius replied, "How is it that you, who make friends out of enemies, call your friends enemies and take from them their armies and provinces?" "It was not fitting," replied Octavian, "that after the death of Calenus such large resources should be left in the hands of such a stripling as Calenus' son while Antony was still far distant. Lucius was excited to frenzy by them and Asinius and Ahenobarbus, who were near by, were about to use them against us. So, too, I took sudden possession of the legions of Plancus, in order that they might not join the Pompeians. His cavalry has actually gone to Sicily." "These matters have been told differently," said Cocceius; "but even Antony did not credit the statements made to him until he was shut out of Brundusium as an enemy." "I gave no order on that subject," replied Octavian, "for I did not know beforehand that he was coming, nor did I anticipate that he would come here with enemies. The Brundusians themselves and the praefect, who had been left with them on account of the raids of Ahenobarbus, of their own motion excluded Antony, who was in league with the common enemy, Pompeius, and was bringing in Ahenobarbus, one of my father's murderers, who had been condemned by vote of the Senate, by judgment of the court, and by the proscription, who besieged Brundusium after the battle of Philippi, and is still blockading the Adriatic coast, who has burned my ships and plundered Italy."

62 But it was agreed between you," said Cocceius, "that you might treat with whomsoever you chose. Yet Antony has not made a treaty with any of the murderers, and he holds your father in no less honour than you do. Ahenobarbus was not one of the murderers, but the vote was cast against him on account of personal animosity, for he had no share whatever in the plots of those days. If we consider him unpardonable because he was a friend of Brutus, are we not in a fair way to be bitter against almost everybody? Antony made an agreement with Pompeius, not to make an aggressive war with him, but either to secure his help in case of an attack by you, or to bring him into good relations with you, since even he has done nothing which should make him irreconcilable. You are the one to blame for these things, for if there had been no war in Italy those men would not have ventured to send ambassadors to Antony." Octavian repeated his accusations, saying, "Manius and Fulvia and Lucius brought war against Italy, and against me as well as Italy; and Pompeius, who did not attack before, now makes descents upon the coast, encouraged by Antony." Cocceius replied, "Not encouraged by Antony, but directed by him; for I will not conceal from you the fact that the rest of Italy, which is destitute of naval defences, will be attacked by a powerful fleet unless you two agree to peace." Octavian, who gave due weight to this artful suggestion, reflected a moment, and then said, "But Pompeius will have the worst of it. He has just been repulsed from Thurii as he deserves." Then Cocceius, having gone over the whole controversy, led the conversation up to the death of Fulvia and the manner of it, saying that she fell sick because she could not bear the anger of Antony and wasted away with grief because he would not see her even when she was ill, and that he was in a manner the cause of his wife's death. "Now that she is dead," he continued, "it only remains for you to tell each other frankly what your suspicions are."

63 In this way Cocceius won the confidence of Octavian and passed the day as his guest, and begged him to write to Antony as the younger man to the older. Octavian said that he would not write to one who was still waging war against him, because Antony had not written to him, but that he would make complaint to Antony's mother, because, although a relative and held in the highest honour by Octavian, she had fled from Italy, as though she could not have obtained everything from him as from her own son. This was his device also for opening a correspondence by writing to Julia. As Cocceius was going away from the camp many of the higher officers advised him of the purpose of the army, and he communicated this and other things he had learned to Antony, so that he might know that they would fight against him because he did not come to an agreement. So he advised Antony that Pompeius should be called back from his ravaging to Sicily, and that Ahenobarbus should be sent somewhither until the treaty of peace should be made. Antony's mother besought him to the same purpose, for she belonged to the Julian clan. Antony apprehended that if the negotiations should fail he would be put to the shame of calling on Pompeius for assistance again, but his mother encouraged him to believe that they would not fail, and Cocceius informed her, intimating that he knew more than he had told. So Antony yielded, and ordered Pompeius back to Sicily, implying that he would take care of their mutual concerns, and sent Ahenobarbus away as governor of Bithynia.

64 When Octavian's soldiers learned these facts they chose deputies and sent the same ones to both commanders. They took no notice of accusations because they had been chosen, not to decide a controversy, but to restore peace. Cocceius was added to their number as a friend of both, together with Pollio from Antony's party and Maecenas from that of Octavian. It was determined that there should be amnesty between Antony and Octavian for the past and friendship for the future. Moreover, as Marcellus, the husband of Octavian's sister Octavia, had recently died, the umpires decided that her brother should betroth her to Antony, which he did immediately. Then Antony and Octavian embraced each other. Thereupon shouts went up from the soldiers and congratulations were offered to each of the generals, without intermission, through the entire day and night.

65 Now Octavian and Antony made a fresh partition of the whole Roman empire between themselves, the boundary line being Scodra, a city of Illyria which was supposed to be situated about midway up the Adriatic gulf. All provinces and islands east of this place, as far as the river Euphrates, were to belong to Antony and all west of it to the ocean to Octavian. Lepidus was to govern Africa, inasmuch as Octavian had given it to him. Octavian was to make war against Pompeius unless they should come to some agreement, and Antony was to make war against the Parthians to avenge their treachery toward Crassus. Octavian was to make the same agreement with Ahenobarbus that Antony had already made. Both of them might freely enlist soldiers in Italy in equal numbers.

These were the last conditions of peace between Octavian and Antony. Straightway each of them sent his friends to attend to urgent business. Antony despatched Ventidius to Asia against the Parthians and against Labienus, the son of Labienus, who, with the Parthians, had made a hostile incursion into Syria and had advanced as far as Ionia during the late troubles.

What Labienus and the Parthians did and suffered I will show in my Parthian history; 66 but in the meantime Helenus, a lieutenant of Octavian, who had repossessed Sardinia by a sudden onset, was driven out again by Menodorus, the lieutenant of Pompeius. Octavian was so exasperated by this that he rejected Antony's endeavours to bring him to an agreement with Pompeius. They proceeded to Rome together and celebrated the marriage. Antony put Manius to death because he had excited Fulvia by his accusations against Cleopatra and had been the cause of so many evils. He also revealed to Octavian the fact that Salvidienus, who was in command of Octavian's army on the Rhone, had had the intention of deserting him, and had sent word to that effect to Antony while he was besieging Brundusium. This secret Antony revealed not with universal approbation, but because of his real frankness and eagerness to show his good-will. Octavian instantly summoned Salvidienus to Rome pretending that he had some private communication to make to him, and that he should send him back to the army. When he came Octavian confronted him with proofs of his treachery and put him to death, and gave his army to Antony, as he considered it untrustworthy.
