Geb, also known as Seb or Keb, was an earth god, grandson of Atum and child of Shu, god of the air, and Tefnut, goddess of moisture. He was one of the original deities.
During the Ptolemaic period, he was associated with the pre-Olympian Titan Greek god of time, Kronos.
During the pre-dynastic period, Geb was worshipped as a goose. God though he was, he had some of the female attributes usually associated with earth deities. As the "Great Cackler," he laid an egg, the symbol of rebirth and renewal.
