Nu (also Nenu, Nunu, Nun), feminine Nut (also Nunut, Nuit, Nent, Nunet, Naunet), 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 Coptic noun "abyss; deep".
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.
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 became occupied, the negative aspect of the Nun (chaos) became the dominant perception, reflecting the forces of disorder that were set loose in the country.
