"“If the Puranic genealogies from the time of the Buddha onward are almost faultless, the presumption naturally is that the earlier genealogies too are not mere figments of the imagination. (…) In the first place a large number of these names occur in the Vedic literature which is quite independent of the Purāṇas. Secondly, even those names which do not occur in the Vedic literature are so archaic that they could not have been coined by the authors of the present Purāṇas in whose time the style of names had completely changed.”"
