" The Caucasus mountain range is probably the most variegated ethnological and linguistic area in the world. It is not a melting pot, as has been said, but a refuge area par excellence where small groups have maintained their identity throughout history. The descendants of the Mediaeval Alans, a Scythic Iranian people, live in the north Caucasus today and are called Ossetes. Iranian cultural influences were strong among the Armenians, Georgians and other peoples of the Caucasus and many times in history large parts of this area were under Persian rule. So it well deserves to be mentioned in a survey of Iran. "
