portion begins at the Caspian Sea, at which the first portion ends. The same sea is also called Hyrcanian. But I must first describe this sea and the tribes which live about it.
This sea is the gulf which extends from the ocean2
towards the south; it is rather narrow at its entrance, but it widens out as it advances inland, and especially in the region of its recess, where its width is approximately five thousand stadia. The length of the voyage from its entrance to its recess might be slightly more than that, since its entrance is approximately on the borders of the uninhabited world. Eratosthenes says that the circuit of this sea was known to the Greeks; that the part along the coast of the Albanians and the Cadusians is five thousand four hundred stadia; and that the part along the coast of the Anariaci and Mardi and Hyrcani to the mouth of the Oxus River is four thousand eight hundred, and thence to the Iaxartes, two thousand four hundred. But we must understand in a more general sense the accounts of this portion and the regions that lie so far removed, particularly in the matter of distances.
