In this crisis of their affairs, some of the allies of Antipater conceived the design of circumventing their enemy by artifice, since it appeared that he was so superior to them in force. They knew how strong was his feeling of reverence and regard for Ptolemy, the King of Egypt, his father-in-law, and they accordingly forged a letter to him in Ptolemy's name, enjoining him to make peace with Antipater, and withdraw from Macedon. Antipater, the letter said, was willing to pay him three hundred talents of silver in consideration of his doing so, and the letter strongly urged him to accede to this offer, and evacuate the kingdom. It was much less difficult to practice a successful deception of this kind in ancient days than it is now, for then writing was usually performed by scribes trained for the purpose, and there was therefore seldom any thing in the handwriting of a communication to determine the question of its authenticity. Pyrrhus, however, detected the imposition which was attempted in this case the moment that he opened the epistle. It began with the words, "King Ptolemy to King Pyrrhus, greeting;" whereas the genuine letters of Ptolemy to his son-in-law were always commenced thus: "The father to his son, greeting." Pyrrhus upbraided the contrivers of this fraud in severe terms for their attempt to deceive him. Still, he entertained the proposition that they made, and some negotiations were entered into, with a view to an amicable settlement of the dispute. In the end, however, the negotiations failed, and the war was continued until Alexander was established on his throne. Pyrrhus then returned to his own kingdom. He received, in reward for his services in behalf of Alexander, a grant of that part of the Macedonian territory which lies upon the coast of the Adriatic Sea, north of Epirus; and thus peace was restored, and all things seemed permanently settled. It will be recollected, perhaps, by the reader, that at the time that Alexander sent for Pyrrhus to assist him, he had also sent for Demetrius, who had been in former years the ally and friend of Pyrrhus. In fact, Deidamia, the sister of Pyrrhus, was Demetrius's wife. Demetrius had been engaged with the affairs of his own government at the time that he received this message, and was not then ready to grant the desired aid. But after a time, when he had settled his own affairs, he placed himself at the head of an army and went to Macedon. It was now, however, too late, and Alexander was sorry to learn that he was coming. He had already parted with a considerable portion of his kingdom to repay Pyrrhus for his aid, and he feared that Demetrius, if he were allowed to enter the kingdom, would not he satisfied without a good part of the remainder.
