Seb is the son of Shu and Tefnut, Seb is the Egyptian Earth god. This was a contrast as at that time most earth gods were female. With his wife who was his sister Nut he had the following children Osiris, Isis, Seth and Nephthys. Seb is also known as Geb or Keb. Sebs sacred animal was the goose. Sebs skin was either black or dark green. The black represented the colour of the fertile Nile mud, and the green represented the colour of the living plants. It is also believed that Seb as well as being the Earth god he also was the guard on the gateway to Egyptian heaven imprisoning wicked souls so they couldn't ascend there.
