Themistocles, in great distress that the Greeks should retire, and lose the advantage of the narrow seas and strait passage, and slip home every one to his own city, considered with himself, and contrived that stratagem that was carried out by Sicinnus. This Sicinnus was a Persian captive, but a great lover of Themistocles, and the attendant of his children. Upon this occasion, he sent him privately to Xerxes, commanding him to tell the king, that Themistocles, the admiral of the Athenians, having espoused his interest, wished to be the first to inform him that the Greeks were ready to make their escape, and that he counseled him to hinder their flight, to set upon them while they were in this confusion and at a distance from their land army, and hereby destroy all their forces by sea. Xerxes was very joyful at this message, and received it as from one who wished him all that was good, and immediately issued instructions to the commanders of his ships, that they should instantly Yet out with two hundred galleys to encompass all the islands, and enclose all the straits and passages, that none of the Greeks might escape, and that they should afterwards follow with the rest of their fleet at leisure. This being done, Aristides, the son of Lysimachus, was the first man that perceived it, and went to the tent of Themistocles, not out of any friendship, for he had been formerly banished by his means, as has been related, but to inform him how they were encompassed by their enemies. Themistocles, knowing the generosity of Aristides, and much struck by his visit at that time, imparted to him all that he had transacted by Sicinnus, and entreated him, that, as he would be more readily believed among the Greeks, he would make use of his credit to help to induce them to stay and fight their enemies in the narrow seas. Aristides applauded Themistocles, and went to the other commanders and captains of the galleys, and encouraged them to engage; yet they did not perfectly assent to him, till a galley of Tenos, which deserted from the Persians, of which Panaetius was commander, came in, while they were still doubting, and confirmed the news that all the straits and passages were beset; and then their rage and fury, as well as their necessity; provoked them all to fight. As soon as it was day, Xerxes placed himself high up, to view his fleet, and how it was set in order. Phanodemus says, he sat upon a promontory above the temple of Hercules, where the coast of Attica is separated from the island by a narrow channel; but Acestodorus writes, that it was in the confines of Megara, upon those hills which are called the Horns, where he sat in a chair of gold, with many secretaries about him to write down all that was done in the fight.
