Haroeris, one of the oldest forms of Horus, was derived from a combination of the falcon-god with an indigenous deity Wer, «the Great One,» a god of light whose eyes were the sun and the moon.
Through increasing emphasis was placed upon the right eye, the sun, Haroeris was worshipped as Mekhenti-irty, «He on whose brow are the Two Eyes» or, on moonless nights as Mekhenti-en-irty, «He on whose brow there are no eyes,» in which aspect he was the patron of the blind.
Mekhenti-irty or Hor-merti was represented holding in his hands the udjat or uraeus eyes of Horus. (see Eye of Horus)
Haroeris, or Horus the Elder, is sometimes recognized as the son or consort of Hathor; also he was the brother of Osiris and Seth. Various myths or legends surround the fight, or battle, involving Horus and Seth in which Hours lost one eye.
One version is that Horus seemed to have recovered with two eyes, one he gave to Osiris as a token of life, and the other for himself.
Horus then ascended the throne justified by the assembly of gods. This myth allowed Horus of Two Eyes to give way to Hor Nubti, «Horus Vanquisher of Seth,» or Horus of Ombos (the cult center of Seth), in other forms of the myth Horus is identified with Re. A.G.H.
