Definition: Atum-Re is a creator sun god especially associated with Heliopolis (the Greek name for the Egyptian On, Oon, or Iunu). He emerged from the primeval waters. His name Atum symbolizes fullness or completion [Tobin]. By spitting or masturbation, he produced a male and female pair of gods, Shu (air) and Tefnut (moisture) who produced the earth and the sky. The primoridal creator god Atum and the solar god Re were put together as early as the Pyramid Texts.
When the Egyptian king dies, he sits on the throne of Atum-Re [Serrano].
For some, Atum-Re is very specifically, the setting sun.
Re"s opponent is Apophis, who is opposed to order. Each day the sun god must fight him to re-emerge and rise each morning.
