Admetus, hearing this, raised him up, together with his own son, even as he still sat holding him, this being the most potent form of supplication. And when, not long afterwards, the Athenians and Lacedaemonians came and made urgent demands for him, Admetus would not give him up, but, since he wished to go to the King, gave him an escort overland to Pydna on the other[*](The Aegean.) sea, the capital of Alexander.[*](King of Macedonia.)
There he found a merchant vessel putting off for Ionia, and going on board was driven by a storm to the station of the Athenian fleet which was blockading Naxos. Themistocles became afraid and told the captain who he was (for he was unknown to those on board) and why he was in flight, adding that if he did not save him he would tell the Athenians that he had been bribed to give him passage; their only chance for safety, he explained, was that no one be allowed to leave the ship until the voyage could be resumed, and he promised that if he complied with his request he would make a fitting return for the favour. The captain did as he was bidden, and after riding out the gale for a day and a night just outside the Athenian station, duly arrived at Ephesus.
And Themistocles rewarded him handsomely with a gift of money (for he soon received from his friends in Athens and from Argos the funds which he had deposited for safekeeping); then proceeding into the interior with one of the Persians who dwelt on the coast, he sent on a letter to King Artaxerxes son of Xerxes, who had lately come to the throne.
