The word is no doubt the ancient representative of the modern Kurdistan, and means a country in which Kurds dwelt.

Now Kurds seem to have been at one time the chief inhabitants of the Mons Masius, the modern Jebel Kara j ah Dagh and Jebel Tur, which was thence called Oordyene, Gordyene, or the Gordisean mountain chain.

But there was another and a more important Cordyene on the opposite side of the river.

The tract to this day known as Kurdistan, the high mountain region south and south-east of Lake Van between Persia and Mesopotamia, was in the possession of Kurds from before the time of Xenophon, and was known as the country of the Carduchi, as Cardyene, and as Cordyene.
