Such then is their mode of life. But even these people are governed by persons called Sceptuchi, and these again are subject to the authority of tyrants, or of kings. The Heniochi had four kings at the time that Mithridates Eupator fled from the country of his ancestors to the Bosporus, and passed through their country, which was open to him, but he avoided that of the Zygi on account of its ruggedness, and the savage character of the people. He proceeded with difficulty along the sea-coast, frequently embarking in vessels, till he came to the country of the Achæi, by whom he was hospitably received. He had then completed a journey from the Phasis of not much less than 4000 stadia.
