Geb is an Egyptian creation god, and god of crops, fertility, and new beginnings. He is the personification of the surface of the earth. Geb is the father of Shu and Tefnut by his sister/wife, Nut. Alternately, he is sometimes seen as the father of Osiris, Isis, Nephthys, Seth, and Horus. Geb's sacred animal is the goose. Earthquakes are thought to be his laughter. His family tree can be seen HERE.
In art, Geb is typically seen as a man reclining under the goddess Nut, or as a man with a goose on his head. His skin is sometimes coloured green, or sometimes has plants on it.
