"Runner" One of the "Four Sons of Heru" depicted in funerary literature as protecting the throne of Wesir in the Underworld, Hapy is depicted as a baboon-headed mummified human on funerary furniture and especially the "canopic" jars which held the organs of the deceased (Hapy's jar held the lungs). Later Hermetic philosophers would equate Hapy with the element of air because of his association with the funerary protectress Nebt-het and the direction of east.
