Ankh-Aapau

Ankh-Aapau is from Egyptian mythology. It is a monstrous serpent from the fifth hour of the River of the Night in the Duat. It lives in the flames that it spits from its mouth. It is watched, along with the snake Tepan, by Sphinxes. In front of these two snakes there are four seated gods with hidden symbols of the god Seker on their knees.
