The crocodile-god, worshipped at the city of Arsinoe, called Crocodilopolis by the Greeks. Sobek was worshipped to appease him and his animals.

According to some evidence, Sobek was considered a fourfold deity who represented the four elemental gods (Ra of fire, Shu of air, Geb of earth, and Osiris of water). In the Book of the Dead, Sobek assists in the birth of Horus; he fetches Isis and Nephthys to protect the deceased; and he aids in the destruction of Set.
