An Ancient Egyptian creator god. Atun was believed to have arisen from Nun (the primordial ocean) and created both men and gods from himself. To create the gods, Atun brought the sky deities Shu (air) and Tefnut (moisture) in to being. Shu and Tefnut then went on to create Seb (earth god) and Nut (sky goddess). Osiris, Isis, Seth and Nephthys were born from Seb and Nut.

Atun is often associated with Ra (sun-god) as an aged aspect, the setting sun.
