Atum was one of the nine main deities of the Egyptian city of Heliopolis and was one of the most important since he created the universe.

He was depicted as a solar god with the head of a ram, a phoenix or a mongoose, or also as a snake, and wearing a double crown.

He was part of the triad of solar deities. Atum represented the evening or setting sun, Ra the noon sun, and Khepri the morning or rising sun of dawn.
