Antiochus, however, was defeated in his first assault upon Alexandria, and finding that he should not soon be able to bring the siege to an end, he sent off an embassy to Rome with a hundred and fifty talents of gold, fifty as a present to the senate, and the rest to be divided among the states of Greece, whose help he might need. At the same time, also, an embassy from the Rhodians arrived in the port of Alexandria, to attempt to restore peace to the country of their old allies. Antiochus received the Rhodian ambassadors in his tent, but would not listen to the long speech with which they threatened him, and shortly told them that he came as the friend of his elder nephew, the young Philometor, and if the Alexandrians wished for peace they should open the gates to their rightful king. Antiochus was, however, defeated in all his assaults on the city, and he at last withdrew his army and returned to Syria. He left Euergetes, King of the Greeks, at Alexandria, and Philometor at Memphis, King of the rest of Egypt. But he kept Pelusium, where he placed a strong garrison that he might be able easily to re-enter Egypt whenever he chose. Ptolemy Macron, the Alexandrian governor of Cyprus, added to the troubles of the country by giving up his island to Antiochus. But he met with the usual fate of traitors, he was badly rewarded; and when he complained of his treatment, he was called a traitor by the very men who had gained by his treachery, and he poisoned himself in the bitterness of his grief. Antiochus, like most invaders, carried off whatever treasure fell into his hands. Egypt was a sponge which had not lately been squeezed, and his court and even his own dinner-table then shone with a blaze of silver and gold unknown in Syria before this inroad into Egypt. By these acts, and by the garrison left in Pelusium, the eyes of Philometor were opened, and he saw that his uncle had not entered Egypt for his sake, but to make it a province of Syria, after it had been weakened by civil war. He therefore wisely forgave his rebellious brother and sister in Alexandria, and sent offers of peace to them; and it was agreed that the two Ptolemies should reign together, and turn their forces against the common enemy. It was most likely at this time, and as a part of this treaty, that Philometor married his sister Cleopatra. It was mainly by her advice and persuasion that the quarrel between the two brothers was for the time healed. On this treaty between the brothers the year was called the twelfth of Ptolemy Philometor and the first of Ptolemy Euergetes, and the public deeds of the kingdom were so dated.
