Kuk (also spelle as Keku) is the deification of the primordial concept of darkness in Egyptian mythology. In the Ogdoad cosmogony, his name meant darkness. As a concept, Kuk was viewed as androgynous, his female form being known as Kauket (also spelled as Keket), which is simply the female form of the word Kuk. Like all 4 dualistic concepts in the Ogdoad, Kuk's male form was depicted as a frog, or as a frog-headed man, and the female form as a snake, or a snake-headed woman. As a symbol of darkness, Kuk also represented obscurity and the unknown, and thus chaos. Also, Kuk was seen as that which occurred before light, thus was known as the bringer-in of light.
