The southern parts of Armenia lie in front of the Taurus, which separates Armenia from the whole of the country situated between the Euphrates and the Tigris, and which is called Mesopotamia. The eastern parts are contiguous to the Greater Media, and to Atropatene. To the north are the range of the mountains of Parachoathras lying above the Caspian Sea, the Albanians, Iberians, and the Caucasus. The Caucasus encircles these nations, and approaches close to the Armenians, the Moschic and Colchic mountains, and extends as far as the country of the people called Tibareni. On the west are these nations and the mountains Paryadres and Scydises, extending to the Lesser Armenia, and the country on the side of the Euphrates, which divides Armenia from Cappadocia and Commagene.
