Hapi
In Egyptian mythology, Hapi (GD: Ahephi) was one of the Four Sons of Horus Hapi was represented as a mummified man with the head of a baboon. He was the protector of the lungs of the deceased, and was protected by the goddess Nephthys.
The name Hapi, spelled identically in most but not all cases, is also the name of the god who was the personification of the River Nile, depicted as a corpulent man (fat signifying abundance) with a crown of lilies or papyrus stems.
