The Ndut people who adhere to the tenets of Serer religion refer to the supreme spirit as Kopé Tiatie Cac in Cangin-Ndut. The name Kopé Tiatie Cac probably derived from the spirit Koox (var : Kooh). Ndut cosmogony posits that, the first humans did not die. The human species were not meant to die following the initial creation. The dog was the first to die at that primordial time. Having witnessed the death of the animal, the Ndut people gave the animal a sacred burial at the foot of a baobab tree, and mourned its death. The women crying and wailing in sadness for the departed dog, attracted the attention of Kopé Tiatie Cac (or Koh) God of death. The spirit angered by the mourning women unleashed death to human kind in the following terms:
What! You make so much noise for a dead dog? Good! You die you too.
The spirit is worshipped through Serer ancestral spirits and saints (i.e. the Pangool). Various matrilineages (both on the paternal and maternal line) play a key role in its evokation. The name koh a variant of the spirit' name, is the femine form. The masculine form is ala.
