Canopic jars, vessels for containing the mummified internal organs of the body, go back to the Old Kingdom. Four jars are traditionally found, and the normal practice up to the end of the New Kingdom was to provide them with human heads. After that point,they tend to take the mixture of animal and human heads associated with the deities who protect the organs.
Two pottery jar lids with human heads have been found in the burial of Senneferi. With their large ears, they are typical of the 18th dynasty. Whether they are part of the same set is very likely. Parts of four ceramic jars have also been identified. They bear just the name of the protective deity, written horizontally in ink. This is not unknown, but perhaps not all that common. We have parts of the names of all four deities: Qebehsenuef, Hapy, Imsety and Duamutef.
