Nun or Nu, as he was sometimes called, represented the primordial waters, a limitless expanse that implied a cycle of destruction and recreation. He symbolized chaos, dark, boundless and turbulent. Nun was also the source of the Nile's annual flooding.
Depicted as a watery man with female breasts representing fertility, he carried a palm frond and wore one another in his headband. With related deities, he was revered at Hermopolis.
