In Egyptian mythology, Duamutef (also known as Tuamutef) was one of the four sons of Horus and a funerary god who protected the stomach and large intestines of mummified corpses, kept in a canopic jar. He was associated with the jackal and was protected by the goddess Neith. Duamutef is represented as a mummified man with the head of a jackal. Interestingly, the Four Sons of Horus continued to be depicted on funerary equipment into the Ptolemaic and Roman eras, and the last known instances are found as late as the 4th century AD, well into the Christian era.
His name is technically transliterated as dw3-mwt=f. This is generally realised as Duamutef, and probably means 'Adoring His Mother'.
