At the other extremity of the Aryan range there was a similar progress southward of similar tribes. Aryan peoples, speaking Sanskrit, had come down through the western passes into North India long before 1000 B.C. There they came into contact with a primordial brunette civilization, the Dravidian civilization, and learnt much from it. Other Aryan tribes seem to have spread over the mountain masses of Central Asia far to the east of the present range of such peoples. In Eastern Turkestan there are still fair, blue-eyed Nordic tribes, but now they speak Mongolian tongues.
Between the Black and Caspian Seas the ancient Hittites had been submerged and “Aryanized” by the Armenians before 1000 B.C., and the Assyrians and Babylonians were already aware of a new and formidable fighting barbarism on the north-eastern frontiers, a group of tribes amidst which the Scythians, the Medes and the Persians remain as outstanding names.
But it was through the Balkan peninsula that Aryan tribes made their first heavy thrust into the heart of the old-world civilization. They were already coming southward and crossing into Asia Minor many centuries before 1000 B.C. First came a group of tribes of whom the Phrygians were the most conspicuous, and then in succession the Æolic, the Ionic and the Dorian Greeks. By 1000 B.C. they had wiped out the ancient Ægean civilization both in the mainland of Greece and in most of the Greek islands; the cities of Mycenæ and Tiryns were obliterated and Cnossos was nearly forgotten. The Greeks had taken to the sea before
