The Roman History · Amm. 23.6.69

Beyond the Seres, towards the north, live the Ariani; their land is intersected by a navigable river called the Arias, which forms a huge lake known by the same name. This district of Asia is full of towns, the most illustrious of which are Bitaxa, Sarmatina, Sotera, Nisibis, and Alexandria, from which last down the river to the Caspian Sea is a distance of fifteen hundred furlongs.
