Nu, being a concept, was viewed as not having a gender, but also had aspects that could be represented as female or male as with most Egyptian deities. Naunet (also spelt Nunet) is the female aspect, which is the name Nu with a female gender ending. The male aspect, Nun, is displayed with a male gender ending. As with the other three four primordial concepts of the Ogdoad, Nu's male aspect was depicted as a frog, or a frog-headed man. In Ancient Egyptian art, Nun also appears as a beardedman, with blue-green skin, representing water. Naunet is represented as a snake or snake-headed woman.
Anyway, is anyone aware of any midrashim about Nun?
