of the company of his friend, carried him with the rest of the court to Susa. This apparently trivial circumstance was attended with important consequences to the Persian empire and to the whole Grecian race. For the next few years everything remained quiet in the Greek cities of Asia; but about B.C. 502 a revolution in Naxos, one of the islands in the AEgean Sea, first disturbed the general repose, and occasioned the war between Greece and Asia. The aristocratical exiles, who had been driven out of Naxos by a rising of the people, applied for aid to Aristagoras, the tyrant of Miletus and the son-in-law of Histiaeus. Aristagoras readily promised his assistance, knowing that, if they were restored by his means, he should become master of the island. He obtained the co-operation of Artaphernes, the satrap of western Asia by holding out to him the prospect of annexing not only Naxos, but all the islands of the AEgean sea, to the Persian empire. He offered at the same time to defray the expense of the armament. Artaphernes placed at his disposal a fleet of 200 ships under the command of Megabates, a Persian of high rank; but Aristagoras having affronted the Persian admiral, the latter revenged himself by privately informing the Naxians of the object of the expedition, which had hitherto been kept a secret. When the Persian fleet reached Naxos they experienced a vigorous resistance; and at the end of four months they were compelled to abandon the enterprise and return to Miletus. Aristagoras was now threatened with utter ruin. Having deceived Artaphernes, and incurred the enmity of Megabates, he could expect no favour from the Persian government, and might be called upon at any moment to defray the expenses of the armament. In these difficulties he began to think of exciting a revolt of his countrymen; and while revolving the project he received a message from his father-in-law, Histiaeus, urging him to this very step. Afraid of trusting any one with so dangerous a message, Histiaeus had shaved the head of a trusty slave, branded upon it the necessary words, and as soon as the hair had grown again sent him off to Miletus. His only motive for urging the Ionians to revolt was the desire of escaping from captivity at Susa, thinking that Darius would set him at liberty in order to put down an insurrection of his countrymen. The message from Histiaeus fixed the wavering resolution of Aristagoras. He forthwith called together the leading citizens of Miletus, laid before them the project of revolt, and asked them for advice. They all approved of the scheme, with the exception of Hecataeus, one of the earliest Greek historians. Aristagoras laid down the supreme power in Miletus, and nominally resigned to the people the management of their own affairs. A democratical form of government was established in the other Greek cities of Asia, which thereupon openly revolted from Persia (B.C. 500).
