"But Jahnāvī is typically a Rigvedic form of the post-Vedic Jāhnavī, and it does not require any "Epic/Purāṇic concepts" to recognize it as the name of a river: a river is a geographical feature, not a mythological entity whose identity is based on traditional historical or mythological texts. On the other hand, Witzel‘s claim that ―Jahnāvī was the wife or a female relation of Jahnu or otherwise connected to him or his clan is definitely based on Epic/Purāṇic concepts: no person named Jahnu is mentioned anywhere in the Rigveda,...Jahnu himself is an Epic/Purāṇic figure...Not only does Witzel accept this Epic/Purāṇic person as the source of the Rigvedic word Jahnāvī, he even visualizes, in the manner of the Amar Chitrakatha comic books, a mysterious lady named Jahnāvī, "the wife or a female relation of Jahnu or otherwise connected to him or his clan", whose very existence is completely unknown to the whole of Vedic and Epic/Purāṇic literature and Indian tradition, but who is apparently so very important in the Rigveda that she is mentioned twice (how many other ladies are mentioned twice in the Rigveda outside of references to people aided by the Aśvins?) in special references, which are worded so peculiarly (what, after all, unless she was a symbol of the motherland, like the present-day Bhāratmātā, has this lady to do with an ―ancient home), that they can be more conveniently and logically translated as references to a river!"
