Geb (pronounced /ɡɛb/), also known as Seb or Keb, is the ancient Egyptian god of the earth, representing the land and the underworld. In Egyptian mythology, Geb is one of the nine deities of the Ennead of Heliopolis, and he is often depicted as a man lying down with his skin covered in green or black, symbolizing the fertile earth. Geb's name is derived from the Egyptian word for "earth," and he is considered the father of snakes, which were seen as embodiments of the life force of the earth. In Hebrew, Geb is translated as גב (Gev). In other languages, Geb is known as Seb in French, Geb in German, and Gebo in Italian. Geb is the son of Shu (god of air) and Tefnut (goddess of moisture), and the brother of Nut (goddess of the sky). He is also the father of Osiris, Isis, Set, and Nephthys by Nut. Geb's role in Egyptian mythology is significant as he represents the physical world and the cycle of life and death, embodying the concept of rebirth and regeneration.
