Horus, a god of the Egyptians, son of Osiris and Isis. He represented the rising sun. He pierces with a spear the serpent Apophis or Apap, the vapors of dawn. He avenges his father Osiris, whom Set or Soutekh, also called Baal, kills, and whom the prayers of Isis resuscitate. The death of Osiris, the grief of Isis, and the final defeat of Set, the god of evil, are common themes in oriental mythologies, and recur in the stories of Cybele and Atys, and of Venus and Adonis. The youthful Horus was held forth as a model for all princes, and as a type of royal virtues. He was often represented as a little child, sometimes in the lap of Isis, and always with a finger on his mouth, which is the common Egyptian sign indicative of extreme youth or infancy. The Greeks identified Horus with their god Har-pocrates, whom they represented also with a finger on the lips; but mistaking the significance of the sign, they regarded it as a symbol of silence, secrecy, and mystery, and ascribed these attributes to the deity. He became accordingly a favorite subject for speculation with the later philosophers. His worship was also carried into Rome, where, probably on account of excesses committed in the mysterious rituals, it was for a while forbidden. The peach was considered the sacred fruit of the god.

The Egyptians also believed that Horus held in conjunction with Anubis the balance in which the hearts of the dead are weighed before Osiris and the 42 assessors, and that he or Smon beheaded those found wanting on the nemma or infernal scaffold.
