Ατούμ is an ancient Egyptian deity associated with creation and the sun. He is often depicted as a man wearing a crown and is considered one of the first gods in the Egyptian mythology. Ατούμ represents the setting sun and is linked to the cycle of life and death. In the Heliopolitan creation myth, Ατούμ is said to have emerged from the primordial waters of Nun and created the first gods, Shu and Tefnut. He embodies the concept of self-creation and is sometimes associated with the pharaohs, who were believed to be his earthly representatives.
