Horus as bright as the sun was explained by a tale, known as "The Contendings of Horus and Seth". In this tale, it was said that Set, the patron of Upper Egypt, and Horus, the patron of Lower Egypt, had battled for Egypt brutally, with neither side victorious, until eventually the gods sided with Horus. As Horus was the ultimate victor he became known as "ḥr.w wr" "Horus the Great", but more usually translated "Horus the Elder". In the struggle, Set had lost a testicle, and Horus's eye was gouged out. Horus represented the eclipsing binary Algol in the Calendar of
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.
