The god Ptaichos is so-called after a passage in Herodotus, which describes the protection-possessing power belonging to the image of a Phoenician dwarf. He was known as the son of Ptah, the craftsman’s god. In Old Kingdom scenes depicting daily life, dwarfs were always present among the workers in precious metal workshops. Ptaichos became very popular from the New Kingdom onwards, often shown holding snakes, making them harmless to people and children, and therefore was thought to provide protection against snakes and crocodiles.
