Ptaichos was one of the forms of god Ptah, sometimes called Ptah Embryon or Ptah Seker. He was a protector of artisans and artists: indeed, in Old Kingdom scenes depicting daily life, dwarfs were always present among the workers in precious metal workshops. The finest images of Ptaichos date to the Third Intermediate period, and later Ptaichos figures often held snakes, which made them harmless to people, especially vulnerable children. Ptaichos was very popular from the New Kingdom onwards, providing protection from creatures like snakes and crocodiles. His head was abnormally large, like the head of a baby, and completely shaven, aside from the lock of childhood.
