Nu (also Nenu, Nunu, Nun), feminine Naunet (also Nunut, Nuit, Nent, Nunet), is the deification of the primordial wateryabyss in the Hermopolitan Ogdoadcosmogony of ancient Egyptian religion. The name is paralleled with nen "inactivity" in a play of words in, "I raised them up from out of the watery mass [nu], out of inactivity [nen]". The name has also been compared to the Coptic noun "abyss; deep".
The name is spelled phonetically with the nw hieroglyph

The Ancient Egyptians envisaged the oceanic abyss of the Nun as surrounding a bubble in which the sphere of life is encapsulated, representing the deepest mystery of their cosmogony. In Ancient Egyptian creation accounts the original mound of land comes forth from the waters of the Nun. The Nun is the source of all that appears in a differentiated world, encompassing all aspects of divine and earthly existence. In the Ennead cosmogony, Nun is perceived as transcendent at the point of creation alongside Atum the creator god.
Beginning with the Middle Kingdom Nun is described as "the Father of the Gods" and he is depicted on temple walls throughout the rest of Ancient Egyptian religious history.
The Ogdoad includes along with Naunet and Nun, Amaunet and Amun; Hauhet and Heh; and Kauket and Kek. Like the other Ogdoad deities, Nu did not have temples or any center of worship. Even so, Nu was sometimes represented by a sacred lake, or, as at Abydos, by an underground stream.
In the 12th Hour of the Book of Gates Nu is depicted with upraised arms holding a "solar bark" (or barque, a boat). The boat is occupied by eight deities, with the scarabdeityKhepri standing in the middle surrounded by the seven other deities.
During the late period when Egypt was occupied by foreign powers, the negative aspect of the Nun (chaos) became the dominant perception, reflecting the forces of disorder that were set loose in the country.
