Title: Horus
Content:  or as a man with a falcon head. The earliest recorded form of Horus is the tutelary deity of Nekhen in Upper Egypt, who is the first known national god, specifically related to the ruling pharaoh who in time came to be regarded as a manifestation of Horus in life and Osiris in death. The most commonly encountered family relationship describes Horus as the son of Isis and Osiris, and he plays a key role in the Osiris myth as Osiris's heir and the rival to Set, the murderer and brother of Osiris. In another tradition Hathor is regarded as his mother and sometimes as his wife. Claudius Aelianus wrote that Egyptians called the god Apollo "Horus" in their own language.
Title: Four sons of Horus
Content:  mummified necropolis god. Imseti, the human, may be linked to Osiris himself or Onuris the hunter. The Egyptians themselves linked them with the ancient kings of Lower and Upper Egypt, the Souls of Pe and Nekhen. In Spells 112 and 113 of the Book of the Dead which have their origins in the earlier Coffin Texts Spells 157 and 158, it is described how Horus has his eye injured, and because of this is given the sons of Horus: "As for Imsety, Hapi, Duamutef, Qebehsenuef, their father is Horus, their mother Isis. And Horus said to Ra, place two brothers in 
Title: Horus
Content:  Horus gradually took on the nature as both the son of Osiris and Osiris himself. He was referred to as Golden Horus Osiris. In the temple of Denderah he is given the full royal titulary of both that of Horus and Osiris. He was sometimes believed to be both the father of himself as well as his own son, and some later accounts have Osiris being brought back to life by Isis.
Title: Harpocrates
Content:   In Egyptian mythology, Horus was the child of Isis and Osiris. Osiris was the original divine pharaoh of Egypt, who had been murdered by his brother Set (by interpretatio graeca, identified with Typhon or Chaos), mummified, and thus became the god of the underworld. The Greeks melded Osiris with their underworldly Hades to produce the essentially Alexandrian syncretism known as Serapis. Among the Egyptians, the full-grown Horus was considered the victorious god of the sun who each day overcomes darkness. He is often represented with the head of a Eurasian sparrowhawk, which was sacred to him, as the hawk flies high above the Earth. 
Title: Horus
Content:  Horus was born to the goddess Isis after she retrieved all the dismembered body parts of her murdered husband Osiris, except his penis, which was thrown into the Nile and eaten by a catfish, or sometimes depicted as instead by a crab, and according to Plutarch's account used her magic powers to resurrect Osiris and fashion a phallus to conceive her son (older Egyptian accounts have the penis of Osiris surviving). After becoming pregnant with Horus, Isis fled to the Nile Delta marshlands to hide from her brother Set, who jealously killed Osiris and who she knew would want to kill their son. There Isis bore a divine son, Horus.
Title: Horus
Content:   Horus was told by his mother, Isis, to protect the people of Egypt from Set, the god of the desert, who had killed Horus' father, Osiris. Horus had many battles with Set, not only to avenge his father, but to choose the rightful ruler of Egypt. In these battles, Horus came to be associated with Lower Egypt, and became its patron. According to The Contendings of Horus and Seth, Set is depicted as trying to prove his dominance by seducing Horus and then having sexual intercourse with him. However, Horus places his hand between his thighs and catches Set's semen, 
Title: Horus
Content:  The Pyramid Texts (c. 2400–2300 BC) describe the nature of the pharaoh in different characters as both Horus and Osiris. The pharaoh as Horus in life became the pharaoh as Osiris in death, where he was united with the other gods. New incarnations of Horus succeeded the deceased pharaoh on earth in the form of new pharaohs.  The lineage of Horus, the eventual product of unions between the children of Atum, may have been a means to explain and justify pharaonic power. The gods produced by Atum were all representative of cosmic and terrestrial forces in Egyptian life. By identifying Horus as the offspring of these forces, then identifying him with Atum himself, and finally identifying the Pharaoh with Horus, the Pharaoh theologically had dominion over all the world.
Title: Osiris
Content:  Osiris is the mythological father of the god Horus, whose conception is described in the Osiris myth (a central myth in ancient Egyptian belief). The myth describes Osiris as having been killed by his brother Set, who wanted Osiris' throne. His wife, Isis, finds the body of Osiris and hides it in the reeds where it is found and dismembered by Set. Isis retrieves and joins the fragmented pieces of Osiris, then briefly revives him by use of magic. This spell gives her time to become pregnant by Osiris. Isis later gives birth to Horus. Since Horus was born after Osiris' resurrection, Horus became thought of as a representation of new beginnings and the vanquisher of the usurper Set. Ptah-Seker (who resulted from the identification of the creator god Ptah with Seker) thus gradually became identified with Osiris, the two becoming Ptah-Seker-Osiris. As the sun was thought to spend the night in the underworld, and was subsequently "reborn" every morning, Ptah-Seker-Osiris was identified as king of the underworld, god of the afterlife, life, death, and regeneration.
Title: Horus
Content:  Heru-ur (or Herwer), (Haroeris to the Ptolemaic Greeks), also known as Horus the Elder, was a form of Horus, where he was the son of Geb and Nut. He was one of the oldest gods of ancient Egypt. He absorbed a number of local gods including a hawk god Nekheny the nome of Nekhen and Wer (a god of light known as “the great one” whose eyes were the sun and moon) to become the patron of Nekhen (Hierakonpolis), the first national god ("God of the Kingdom") and later the patron god of the pharaohs. Nekhen was a powerful city in the pre-dynastic period, and the early capital of Upper Egypt. By the Old Kingdom he was simply referred to as Horus and had become the first national god and the patron of the Pharaoh. He was called the son of truth – signifying his role as an important upholder of Maat. His right eye was the Sun and the left one was the Moon. Heru-ur was sometimes depicted fully as a falcon, he was sometimes given the title Kemwer, meaning "(the) great black (one)". Other variants include Hor Merti 'Horus of the two eyes' and Horkhenti Irti.
Title: Hathor
Content:   Hathor was considered the mother of various child deities. As suggested by her name, she was often thought of as both Horus's mother and consort. As both the king's wife and his heir's mother, Hathor was the mythic counterpart of human queens. Isis and Osiris were considered Horus's parents in the Osiris myth as far back as the late Old Kingdom, but the relationship between Horus and Hathor may be older still. If so, Horus only came to be linked with Isis and Osiris as the Osiris myth emerged during the Old Kingdom. Even after Isis was firmly established as Horus's mother, Hathor continued
