Tianza Ngombe was the primordial serpent.
The mother of all things, Tianza Ngombe (Chinaweshi, Chinawezi), divided up the world with the lightning, Nzashi, her husband. Nzashi set himself up in the sky with the sun, the moon, Venus, and the stars; his urine became the beneficial rain. Tianza Ngombe had the earth and the rivers. When the thunder rumbles in the sky, Tianza Ngombe responds in the waters and the rivers become swollen.
Tianza Ngombe bore a son, Konde, and a daughter, Naweshi. These two had incestuous relations, and they had three children, among them Lueshi (Lueji). At the confluence of two rivers, Lueshi met Chibinda Ilunga, the master hunter and chief. See also: Chibinda Ilunga, Chinawezi, Lueji.
