He is probably most well-known as the protector of the ruler of Kemet.
The Kemites believed that the pharaoh was the ‘living Heru’.
Heru was the son of the god Ausar and the Goddess Auset who were 2 of the 9 Kemetic gods of the Ennead. Ausar and Auset ruled Upper and Lower Kemet as coregents. Ausar made it his task to bring knowledge to the world and while he traveled the Earth Auset ruled the empire.
All loved Auset and Ausar except for their brother who was the god of Chaos and storms. Auset was murder by his brother when Set found out that he had Auset had fathered a child by Nephthys, who was the wife of Seth. Seth dismembered his brothers body and scattered his parts around the world. But Auset so loved her husband that she found his body, and with the help of Annubis and Thoth resurrected Ausar long enough for he and his beloved wife Auset to conceive a son who would be Horus.
Auset had to keep her son’s birth a secret because Seth ruled the two kingdoms and we would see the heir of his brother as a threat to his position. With the help of he sister Nepthys she raised her son to strong and good. He was educated by Thoth, the god of wisdom. In time he grew to a strong a powerful adult and was ready to challenge his uncle for his rightful throne.
They waged several bloody battles, each bearing terrible wounds. Horus lost an eye while Seth lost a testicle. Eventually Heru was able to defeat his uncle and assumed the throne that was rightfully his. In one epic Egyptian myth, Seth damaged Horus’s left eye. The damage to what was known as the “moon eye” set in motion the phases of the moon. The god Thoth was able to restore Heru’s damaged eye. The eye of Heru, represented as the wedjat eye, was born as one of the most powerful and popular symbols of Egypt. It was seen as the watchful eye. The eye saw everything and protected the world from the always threatening chaos. The battle between Heru and Seth reached the Kemites as a story of hope. In a time of frequent rebellions and invading occupiers, the defeat of Seth became a powerful symbol. Many Egyptian temple reliefs show Heru’s triumph over Seth in a variety of tales.
The signifigance of Heru is in his position of birth, per the myth of the Ennead of Atum Ra, Heru is the first to be born of Earth. His mother compensating for the missing phallus of her husband, fashioned a phallus of gold by which the energy of Ausar would be passed to her through this Earthly vessel. Heru would in later tales be noted as the progenitor of human life on Earth and all Pharaohs were descended from him
As early as the late pre-dynastic times, cults began associating with Horus. Although cults were common for Egyptian gods, many cults focused on specific local gods. Heru was a well-known god with popularity throughout all of Kemet. Examples of his importance are found throughout all of Egypt in temple remains, monuments and coffin texts.
The most significant tribute to Heru stands as the Temple of Edfu. Located 60 kilometers north of Aswan, the structure is considered one of the best preserved temples in Egypt. Cult worship of Hrtu began in the Delta, spreading south throughout the reign of Ptolemy III. Construction of the temple began around 237 BCE. Over the course of the 180 years of construction, Hrtu was worshiped at Edfu for constantly battling Seth and protecting the world from darkness.
He was the protector of the royalty of Egypt, avenger of wrongs, defender of order, uniter of the two lands and, based on his battles with Set, a god of war regularly invoked by Kemitic rulers before battle and praised afterwards
One of the most important gods of ancient Kemet the worship of Heru spanned over 5,000 years. With mention in records from the late pre-dynastic period through Roman times, Heru became the catch-all name for many different gods associated with falcons. Kemetic mythology features many different versions of his name, family and importance.
Also known as Horus of Two Eyes, his left eye represented the sun and his right eye represented the moon. With the power of the sun and the healing of the moon, Horus ruled both the day and the night. In the earliest forms, Kemites viewed him as the brother of Ausar and Seth.
Over time, Egyptians began to combine the idea of Horus and Ra into one god, Ra-Harakhte. Often pictured with a solar disk behind his head, the Ra-Harakhte version of Heru was the sun god, responsible for the sun’s path across the sky.
