The Roman History · Amm. 23.6.40

There are many rivers in this country, the principal of which are the Choaspes, the Gyndes, the Amardus, the Charinda, the Cambyses, and the Cyrus, to which, on account of its size and beauty, the elder Cyrus, that amiable king, gave its present name, abolishing that which it used to bear, when he was proceeding on his expedition against Scythia; his reason being that it was strong, as he accounted himself to be, and that making its way with great violence, as he proposed to do, it falls into the Caspian Sea.
