Nu is the one of the eight deities of the Ogdoad representing ancient Egyptian primordial Chaos from which the Primeval Mound appeared. He is coupled with goddess Naunet and appears in antropomorphic form but with the head of a frog. No cult is addressed to Nun but he is typically depicted in ancient Egyptian art holding aloft the solar barque or the sun disc. He may appear greeting the rising sun in the guise of a baboon. Nun is otherwise symbolized by the presence of a sacred cistern or lake as in the sanctuaries of Karnak and Dendara.
