The language of the Rig-veda," he writes in one place, "is certainly no more different from that of the Avestan Gathas than is Old English from Old High German, and therefore they must be assigned to approximately the same age: and the relation between the language of the Gathas and that of Old Persian inscriptions of the sixth century B.C. cannot be better visualised than by comparing the former with Gothic and the latter with Old High German. Now, if the inscriptions of the Achaemenid emperors of Iran were composed in Old High German, what would be the date assigned to Ulfila's Bible? Surely something like 1000 B.C. This then would be the approximate date of the Gathas of the Avesta - with which the Rigveda in its present form must have been more or less contemporaneous.

The Iranians had retained a distinct memory of the Indo-Iranian common home in their mythology but the Indo-Aryans... have nothing to say on the point. [... There is a ] distinctively Indian Rigvedic culture... a distinct product of the Indian soil.

If the forefathers of the Vedic Aryans were still in Cappadocia in the 14th century BC on their march towards India, there would be no time left for them to forget all their previous history before giving the final form to the Rigvedic hymns not later than 1000 BC.
