Four sons of Horus 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: The injury of Horus's eye is part of the myth cycle known as the Contending of Horus and Set recounting how they fought over the crown of Egypt. In a unique illustration in the tomb of Ay the sons of Horus are shown wearing the red and white crowns as the Souls of Pe and Nekhen,
Horus and Harsiese "Horus, Son of Isis". Nekheny may have been another falcon god worshipped at Nekhen, city of the falcon, with whom Horus was identified from early on. Horus may be shown as a falcon on the Narmer Palette, dating from about the 31st century BC. In early Egypt, Horus was the brother of Isis, Osiris, Set and Nephthys. As different cults formed, he became the son of Isis and Osiris. Isis remained the sister of Osiris, Set and Nephthys. The "Pyramid Texts" (c. 2400–2300 BC) describe the nature of the pharaoh in different characters as both Horus and Osiris.
