This mountain overhangs both the Euxine and the Caspian seas, forming a kind of rampart to the isthmus which separates one sea from the other. To the south it is the boundary of Albania and Iberia, to the north, of the plains of the Sarmatians. It is well wooded, and contains various kinds of timber, and especially trees adapted to ship-building. Eratosthenes says that the Caucasus is called Mount Caspius by the natives, a name borrowed perhaps from the Caspii. It throws out forks towards the south, which embrace the middle of Iberia, and touch the Armenian and those called the Moschic mountains,937 and besides these the mountains of Scydises, and the Paryadres. All these are portions of the Taurus, which forms the southern side of Armenia, and are broken off in a manner from it towards the north, and extend as far as Caucasus, and the coast of the Euxine which lies between Colchis and Themiscyra.938
