"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... It really cannot be proved that the Vedic Aryans retained any memory of their extra-Indian associations."
