We now come to the peculiar goose! According to ancient Greek mythology and legend he is identified with the goose, the bird which, in later times was sacred to him as he was believed to have made his way through the air in the form of a goose. The word "seb," was also used as a name of the god in reference to a "peculiar species" of goose of the same name. Seb is the Egyptian name for a certain species of goose. Finally, the symbol of the goose is in allusion to the idea that he made the primeval egg from which the world came into being. He is therefore often called the "Great Cackler". The pictures of hieroglyphics depicting Geb shows the goose standing or sitting on the head of the god.
