6. These things he was wont to say, since he was one who had a desire for perilous enterprise and wished to be himself the governor of Hellas under the king. So in time he prevailed upon Xerxes and persuaded him to do this; for other things also assisted him and proved helpful to him in persuading Xerxes. In the first place there had come from Thessaly messengers sent by the Aleuadai, who were inviting the king to come against Hellas and were showing great zeal in his cause, (now these Aleuadai were kings of Thessaly): and then secondly those of the sons of Peisistratos who had come up to Susa were inviting him also, holding to the same arguments as the Aleuadai; and moreover they offered him yet more inducement in addition to these; for there was one Onomacritos an Athenian, who both uttered oracles and also had collected and arranged the oracles of Musaios; 4 and with this man they had come up, after they had first reconciled the enmity between them. For Onomacritos had been driven forth from Athens by Hipparchos the son of Peisistratos, having been caught by Lasos of Hermion interpolating in the works of Musaios an oracle to the effect that the islands which lie off Lemnos should disappear 5 under the sea. For this reason Hipparchos drove him forth, having before this time been very much wont to consult him. Now however he had gone up with them; and when he had come into the presence of the king, the sons of Peisistratos spoke of him in magnificent terms, and he repeated some of the oracles; and if there was in them anything which imported disaster to the Barbarians, of this he said nothing; but choosing out of them the most fortunate things he told how it was destined that the Hellespont should be yoked with a bridge by a Persian, and he set forth the manner of the march. He then thus urged Xerxes with oracles, while the sons of Peisistratos and the Aleuadai pressed him with their advice. 7. So when Xerxes had been persuaded to make an expedition against Hellas, then in the next year after the death of Dareios he made a march first against those who had revolted. Having subdued these and having reduced all Egypt to slavery much greater than it had suffered in the reign of Dareios, he entrusted the government of it to Achaimenes his own brother, a son of Dareios. Now this Achaimenes being a governor of Egypt was slain afterwards by Inaros the son of Psammetichos, a Libyan.
