Polycrates was much pleased at the prospect of a large accession to his funds, and he sent the messenger, as Oretes had proposed. Oretes prepared to receive him by filling a large number of boxes nearly full with heavy stones, and then placing a shallow layer of gold or silver coin at the top. These boxes were then suitably covered and secured, with the fastenings usually adopted in those days, and placed away in the royal treasuries. When the messenger arrived, the boxes were brought out and opened, and were seen by the messenger to be full, as he supposed, of gold and silver treasure. The messenger went back to Polycrates, and reported that all which Oretes had said was true; and Polycrates then determined to go to the main land himself to pay Oretes a visit, that they might mature together their plans for the intended campaigns. He ordered a fifty-oared galley to be prepared to convey him. His daughter felt a presentiment, it seems, that some calamity was impending. She earnestly entreated her father not to go. She had had a dream, she said, about him, which had frightened her excessively, and which she was convinced portended some terrible danger. Polycrates paid no attention to his daughter's warnings. She urged them more and more earnestly, until, at last, she made her father angry, and then she desisted. Polycrates then embarked on board his splendid galley, and sailed away. As soon as he landed in the dominions of Oretes, the monster seized him and put him to death, and then ordered his body to be nailed to a cross, for exhibition to all passers by, as a public spectacle. The train of attendants and servants that accompanied Polycrates on this expedition were all made slaves, except a few persons of distinction, who were sent home in a shameful and disgraceful manner. Among the attendants who were detained in captivity by Oretes was a celebrated family physician, named Democedes, whose remarkable and romantic adventures will be the subject of the next chapter. Oretes committed several other murders and assassinations in this treacherous manner, without any just ground for provocation. In these deeds of violence and cruelty, he seems to have acted purely under the influence of that wanton and capricious malignity which the possession of absolute and irresponsible power so often engenders in the minds of bad men. It is doubtful, however, whether these cruelties and crimes would have particularly attracted the attention of Darius, so long as he was not himself directly affected by them. The central government, in these ancient empires, generally interested itself very little in the contentions and quarrels of the governors of the provinces, provided that the tribute was efficiently collected and regularly paid.
