Protectors of the deceased from the
Twenty-sixth Dynasty (664–525 BC) Texts from later periods continue to invoke the sons of Horus for protection in the afterlife as the Pyramid Texts do. In many texts they were said to protect
Osiris, the funerary deity whose
mythological death and resurrection served as the template for
ancient Egyptian funerary practices. Some texts even refer to them as the sons of Osiris rather than Horus. In a Middle Kingdom ritual, recorded in the
Dramatic Ramesseum Papyrus, the sons of Horus aid Osiris in his rejuvenation after death, fight the followers of his enemy
Set, and restore the lost
Eye of Horus to their father. Spell 137 of the
Book of the Dead from the
New Kingdom ( 1550–1070 BC) says to them, "as you spread your protection over your father Osiris-
Khentiamentiu, so spread your protection over [the deceased person]". In the tenth section of the New Kingdom
Book of Gates, a funerary text that depicts the underworld in detail, the four sons are portrayed holding chains that bind the malign beings called
wmmtj, meaning "snakes". The four sons developed a specialized connection with the internal organs of the deceased. During the
mummification process, four internal organs—the lungs, liver, stomach, and intestines—were removed from the body and dried before being placed in the burial, usually separately from the body. In the late Old Kingdom, these organs began to be placed in a set of jars known as
canopic jars, and during the
First Intermediate Period ( 2181–2055 BC), the jars began to be inscribed with texts invoking the sons of Horus. No text specifies which of the sons protect which organ. Burials in which the jars and organs survive show that the most common arrangement was for Imsety to guard the liver, Hapy the lungs, Duamutef the stomach, and Qebehsenuef the intestines, but many variations are known. For instance, in some cases Hapy protected the stomach and Duamutef the lungs. The sons of Horus themselves were thought to be under the protection of four goddesses, usually Isis for Imsety,
Nephthys for Hapy,
Neith for Duamutef, and
Serqet for Qebehsenuef. In the Middle Kingdom, this scheme could vary and sometimes included different goddesses, so that
Sendjet guarded Duamutef and
Renenutet guarded Qebehsenuef. In some inscriptions from Middle Kingdom coffins, the goddesses are invoked to protect the son of Horus "who is in you [the deceased]", suggesting that the sons were equated with the internal organs as well as being their protectors.
Directions and regions of the cosmos The sons of Horus were also connected with the sky or parts of the cosmos as the Egyptians envisioned it. In the New Kingdom, they were sometimes thought of as stars in the northern sky or as birds flying to the four corners of the world.
Bernard Mathieu suggests that they were equated with the four stars at the corners of the constellation
Orion (
Saiph,
Betelgeuse,
Bellatrix, and
Rigel) and with four of the stars in
Ursa Major (
Megrez,
Phecda,
Merak, and
Dubhe). Several Egyptologists have suggested that the four sons were equated with the four pillars that supported the vault of the sky in Egyptian cosmology. They were also connected with regions of Egypt: they were sometimes equated with the
Souls of Nekhen and Pe, a set of deities that represented the
Predynastic rulers of
Upper Egypt in the south and
Lower Egypt in the north. Hapy and Duamutef were linked with the Lower Egyptian city of
Buto, and Imsety and Qebehsenuef with the Upper Egyptian city of
Nekhen. Egyptian beliefs drew analogies between the human body and the cosmos, and these analogies were particularly visible in burial customs. In Middle Kingdom burials, bodies were laid out with the head to the north and the feet to the south. The texts that decorated coffins in this period placed some deities in consistent locations, thus linking them with particular directions. Imsety and Hapy were invoked at the head of the coffin, with Imsety on the left and Hapy on the right, thus placing Imsety in the northeast and Hapy in the northwest. Duamutef and Qebehsenuef were invoked at the foot of the coffin, with Duamutef on the left and Qebehsenuef on the right, thus placing Duamutef in the southeast and Qebehsenuef in the southwest. Canopic chests of the time placed each deity in equivalent positions. These orientations suggest that the sons of Horus were linked with the four corners of the Egyptian cosmos. Their orientation may be related to the positions of each organ: the lungs and liver sit higher in the body, thus fitting the northerly position of Imsety and Hapy, while the stomach and intestines are lower down, matching the southerly position of Duamutef and Qebehsenuef. The sons' positions shifted in the New Kingdom, when burials came to be laid out with the head to the west and the feet in the east. On some coffins, Imsety and Hapy remained at the head and Duamutef and Qebehsenuef at the foot, but in each pair, the deity who had been on the left side was moved to the right, and vice versa. In other cases, each of the sons of Horus appeared on a side wall of the coffin or canopic chest: Imsety in the south, Hapy in the north, Duamutef in the east, and Qebehsenuef in the west. The latter placement, with the sons of Horus on four sides rather than four corners, links the four deities with the
cardinal directions rather than the corners of the cosmos. The coexistence of the two systems of orientation suggests that the Egyptians did not sharply distinguish the four corners from the four directions. ==Iconography==
