From Tauric Armenia and the land of Celesene the River Euphrates, flowing to the right of the Tigris, flows around an extensive territory, and since many rivers join it and among them the Arsinus, whose copious stream flows down from the land of the so-called Persarmenians, it becomes naturally a great river, and flows into the land of the people anciently called White Syrians but now known as the Lesser Armenians, whose first city, Melitene, is one of great importance.
