The worship of Horus was brought from the outside by neighboring tribes who invaded and then settled into Egypt. He was their god of war, but was quickly absorbed into the state religion, first as a son of Ra, then changing to become the son of Osiris. He was the protector and guide to the pharaoh and later pharaohs were believed to be his avatar on earth. Horus was also the patron of young men and the ideal of the dutiful son who grows up to become a just man.
The most popular story of Horus is the one in which he grows to manhood to avenge the death of his father Osiris by battling against his cruel uncle Set. In many writings, he is said to continue to battle Set daily to ensure the safety of the world. This is a pic of Horus at Edfu. God of the noontime sun.
