What is "tatenen"

Tatenen (also Ta-tenen, Tatjenen, Tathenen, Tanen, Tenen, Tanenu, and Tanuu) was the god of the primordial mound in ancient Egyptian religion. His name means risen land or exalted earth, as well as referring to the silt of the Nile. As a primeval chthonic deity, Tatenen was identified with creation. He was an androgynous protector of nature from the Memphis area (then known as Men-nefer), the ancient capital of the Aneb-Hetch nome in Lower Egypt.

Tatenen represented the Earth and was born in the moment it rose from the watery chaos, analogous to the primeval mound of the benben and mastaba and the later pyramids. He was seen as the source of "food and viands, divine offers, all good things", as his realms were the deep regions beneath the earth "from which everything emerges", specifically including plants, vegetables, and minerals. His father was the creator god Khnum, who made him on his potter's wheel of Nile mud at the moment of creation of Earth. This fortuity granted him the titles of both "creator and mother who gave birth to all gods" and "father of all the gods". He also personified Egypt (due to his associations with rebirth and the Nile) and was an aspect of the earth-god Geb, as a source of artistic inspiration, as well as assisting the dead in their journey to the afterlife.

He is first attested in the Coffin Texts, where his name appears as Tanenu or Tanuu, 'the inert land', a name which characterizes him as a god of the primeval condition of the earth. Middle Kingdom texts provide the first examples of the form Tatenen.

With a staff Tatenen repelled the evil serpent Apep from the Primeval Mound. He also had a magical mace dedicated to the falcon, venerated as "The Great White of the Earth Creator". In one interpretation, Tatenen brought the Djed-pillars of stability to the country, although this is more commonly attributed to Ptah.
