The four sons of Horus (Imsety, Hapy, Duamutef, and Quebsenuef) were responsible for preserving the vital organs of the deceased in the Afterlife. Each of the four was charged with protecting a certain organ, Duamutef – the stomach; Imsety – the liver; Hapy – the lungs; and Quebsenuef – the intestines. They were usually represented on the lids of four canopic jars that accompanied the mummified bodies.
