Often identified with the sun, Horus (also known as Her, Heru, Hor or Har) was known as one of the most powerful gods of the Egyptian pantheon. He is the falcon-headed sun god and the prince of Egypt. Horus was occasionally shown in art as a naked boy with a finger in his mouth sitting on a lotus with his mother. In the form of a youth, Horus was referred as Neferhor, Nephoros or Nopheros (literally known as Good Horus). He is the son of the god Osiris and Isis, seeks revenge for his father's death at the hands of the god Set.
He is most famous for his battle with the god Set for supremacy; The gods passed judgment on the battle between Horus and Set, ultimately favoring Horus as the god of day. It is said that he and Set have a never-ending battle, and when the sun rises, Horus begins to triumph, but when the sun sets, Set gains the upper hand. During these battles, Horus loses an eye until it is restored by Thoth. Thus, the "eye of Horus" symbol in Egyptian art represents healing.
Since Horus was said to be the sky, he was considered to also contain the Sun and Moon. It became said that the Sun was his right eye and the Moon his left, and that they traversed the sky when he, a falcon, flew across it. Later, the reason that the Moon was not 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 "Horus the Great", but more usually translated "Horus the Elder". In the struggle, Set had lost a testicle, and Horus' eye was gouged out.
Horus the Younger, Harpocrates to the Ptolemaic Greeks, is represented in the form of a youth wearing a lock of hair on the right of his head while sucking his finger. In addition, he usually wears the united crowns of Egypt, the crown of Upper Egypt and the crown of Lower Egypt. He is a form of the rising sun, representing its earliest light.
The pharaoh of Egypt was also thought to be the human personification of Horus or his son, and was responsible for maintaining Ma'at, or balance, in Egypt. When the pharaoh died, he became the embodiment of Osiris.
Horus appears as a demon of the Deity Race. Aleph can recruit him after reaching Level 37 or above.
