Canopic jars were used to store the organs that were removed from the body during the mummification process, specifically the lungs, liver, stomach, and intestines. The term "canopic" to describe such vessels is a misnomer, being derived from the port city of Canopus, where the god Osiris was worshipped in the form of a jar.
