The above-mentioned Amasis was the Egyptian king against whom Cambyses, son of Cyrus, made his expedition; and with him went an army composed of the many nations under his rule, among them being included both Ionic and Aeolic Greeks. The reason of the invasion was the following. Cambyses, by the advice of a certain Egyptian, who was angry with Amasis for having torn him from his wife and children and given him over to the Persians, had sent a herald to Amasis to ask his daughter in marriage. His adviser was a physician, whom Amasis, when Cyrus had requested that he would send him the most skilful of all the Egyptian eye-doctors, singled out as the best from the whole number. Therefore the Egyptian bore Amasis a grudge, and his reason for urging Cambyses to ask the hand of the king's daughter was, that if he complied, it might cause him annoyance; if he refused, it might make Cambyses his enemy. When the message came, Amasis, who much dreaded the power of the Persians, was greatly perplexed whether to give his daughter or no; for that Cambyses did not intend to make her his wife, but would only receive her as his concubine, he knew for certain. He therefore cast the matter in his mind, and finally resolved what he would do. There was a daughter of the late king Apries, named Nitetis, a tall and beautiful woman, the last survivor of that royal house. Amasis took this woman, and decking her out with gold and costly garments, sent her to Persia as if she had been his own child. Some time afterwards, Cambyses, as he gave her an embrace, happened to call her by her father's name, whereupon she said to him, "I see, O king, thou knowest not how thou has been cheated by Amasis; who took me, and, tricking me out with gauds, sent me to thee as his own daughter. But I am in truth the child of Apries, who was his lord and master, until he rebelled against him, together with the rest of the Egyptians, and put him to death." It was this speech, and the cause of quarrel it disclosed, which roused the anger of Cambyses, son of Cyrus, and brought his arms upon Egypt. Such is the Persian story. The Egyptians, however, claim Cambyses as belonging to them, declaring that he was the son of this Nitetis. It was Cyrus, they say, and not Cambyses, who sent to Amasis for his daughter. But here they mis-state the truth. Acquainted as they are beyond all other men with the laws and customs of the Persians, they cannot but be well aware, first, that it is not the Persian wont to allow a bastard to reign when there is a legitimate heir; and next, that Cambyses was the son of Cassandane, the daughter of Pharnaspes, an Achaemenian, and not of this Egyptian. But the fact is that they pervert history in order to claim relationship with the house of Cyrus. Such is the truth of this matter. I have also heard another account, which I do not at all believe: that a Persian lady came to visit the wives of Cyrus, and seeing how tall and beautiful were the children of Cassandane, then standing by, broke out into loud praise of them, and admired them exceedingly.
