Situated on a bay of this kind, and occupying the most easterly point of the whole sea, is Dioscurias,939 called the recess of the Euxine Sea, and the extreme boundary of navigation, for in this sense we are to understand the proverbial saying,
“To Phasis where ships end their course.”
Not as if the author of the iambic intended to speak of the river, nor of the city of the same name upon the river, but Colchis designated by a part, because from the city and the river there remains a voyage of not less than 600 stadia in a straight line to the recess of the bay. This same Dioscurias is the commencement of the isthmus lying between the Caspian Sea and the Euxine. It is a common mart of the nations situated above it, and in its neighbourhood. There assemble at Dioscurias 70 or, according to some writers who are careless in their statements,940 300 nations. All speak different languages, from living dispersed in various places and without intercourse, in consequence of their fierce and savage manners. They are chiefly Sarmatians, but all of them Caucasian tribes. So much then respecting Dioscurias.
