As the son of Shu and Tefnut, Seb was the Egyptian earth god. He was masculine, contrasting with the tradition that the guardian of the earth was usually female. Osiris, Isis, Seth, and Nephthys were his children and he was brother and husband to Nuit. In early Egyptian history, Seb was known as Geb or Keb, but in later forms of the language it became Seb. Seb's sacred animal and symbol was the goose; he was often referred to as the "Great Cackler." His skin was either green or black. The green represented the the color of living things and the black was the color of the fertile Nile mud. It was believed that Seb imprisoned wicked souls, so they couldn't ascend to heaven.
