Benben

Benben or Ben-ben, in Egyptian mythology, specifically in the Heliopolitan tradition, was the mound that arose from the primordial waters, Nu, and on which the creator god Atum settled. In the Pyramid Texts, e.g. Utterances 587 and 600, Atum himself is at times referred to as "mound". It was said to have turned into a small pyramid, located in Annu, which was the place Atum was said to dwell within. Other cities developed their own myths of the primeval mound. At Memphis the god Tatenen, an earth god and the origin of all things in the shape of food and viands, divine offers, all good things was the personification of the primeval mound.
