He was a solar divinity, the primitive patron of Eliopoli. He was represented by the figure of a man, with the pharaoh’s crown and he was associated with Shu and Tefnut, to form a threefold. He created himself, before he generated Shu and Tefnut, and was the primordial god in Eliopoli. Under the II dynasty, he was assimilated to the sun Ra, in this way, the God began to symbolize the sun that goes to sleep. In “The book of what is in Ade”, Ra has Atum’s features when he passes the nocturne world. Atum’s sacred animals were the lion, the snake and the Ichneumon.
