Nu was shown usually as male but also had aspects that could be represented as female or male. Nunet (/ˈnuːˌnɛt/; also spelt Naunet) is the female aspect, which is the name Nu with a female gender ending. The male aspect, Nun, is written with a male gender ending. As with the 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 bearded man, with blue-green skin, representing water. Naunet is represented as a snake or snake-headed woman.
