(Hapi) Not to be confused with Hapy, the God of the Nile’s annual flood ( ‘Hapy (2)‘ here), nor with the God more commonly known as Apis, but rather one of the four ‘sons of Horus‘. Hapy’s name has been interpreted as “runner”—see, in this respect, CT spell 521: “I am Hapy, and I have come to you [the deceased]. My father Horus said to me: Run after my father Osiris and open his mouth,” i.e., restore his power to breathe. Hapy is depicted as a baboon-headed mummy on the jar containing the lungs of the deceased. Together with Horus and Imsety, Hapy is said in CT spell 157/BD spell 112 to be among the “Souls [Bau] of Pe,” a district of the town of Buto in Lower Egypt. It has been suggested (Taylor 2001, p. 65) that the original form of Hapy’s name was “Hepwy”, with the “-wy” ending denoting a dual, and hence that Hapy, like Imsety, was originally a pair of deities, in this case masculine.
