The intestines, stomach, lungs and liver were removed from the body as part of ancient Egyptian mummification. The organs were placed in individual carved limestone canopic jars, each with a different shaped head representing four corresponding Egyptian gods – the Sons of Horus. Each ‘Son’ looked after a different body part. Human-headed lids, such as this one, represent Imsety (Mestha), guardian of the liver. The jackal-headed Duamutef was the guardian of the stomach. The falcon-headed Qebhsnuf looked after the intestines; the baboon-headed Hapi looked after the lungs.
