"Contrary to popular scholarly opinion, the genealogies found in the Puranas, which list over a hundred and twenty kings in one Vedic dynasty alone, fit into the new model of ancient Indian history. The Puranic records are far more trustworthy than has hitherto been assumed. They are the distillate of countless generations of remembered knowledge, especially knowledge concerning the vicissitudes of royal houses. They date back to the third millennium B.C.E. and earlier. Greek accounts point to the existence of Indian royal lists (perhaps coinciding with those of the Puranas) that are reported to go back to the seventh millennium B.C.E."
