Horus - as the son of Osiris and Isis and the heir of his father - is the heir also to the earthly realm, the avenger of the father, the young warrior-god, who, due to his mithological role, has become a symbol of the divine origin of the kingdom in Egypt.
The prevailing pharaoh as the owner of the Double Crown is the terrestrial manifestation of Horus himself. On the portrayals he appears as falcon or falcon-headed man.
The cult of the deity is timeless in the history of the Two Lands, his centre of worship was firs of all in Nehen (Hieraconpolis, means "falcon city"), one of the two capitals during the pre-dynastic age, but due to the identification with the king, the god was widely respected all through the entire country. (His temple in Edfu which was built during the reign of the Ptolemies is worth your attention.)
Beside Osiris and Isis, Horus has the most extensive myth, another evidence of his stressed position in the Egyptian pantheon. His most famous story describes his fight for the right of succession with his uncle, Seth. This myth consists of many episodes and introduces the gods in their various characters - not emphasising only the positive features, what more sometimes revealing their human, sometimes frail faces.
The two gods (Horus and Seth) has been "abusing" the committee of the Devine Ennead for 60 years with their dispute: Who shall inherit the crown of Osiris (who had been murdered by Seth, then Isis resurrected him and gave birth to a son, and he descended to the Underworld to continue his reign there), the brother or the son?
For us it would be reasonable that the succession goes from father to son but in the early dynastic age the old tribal traditions from the earlier periods were still alive in Egypt and those required the oldest male relative to be the heir of the deceased. (Obviously this issue was a disputed subject not only among gods but humans too.)
The Divine Ennead cannot come to a decision, therefore they make the opponents confront each other in many tests and simultaneously they are in continual correspondence with other gods hoping that a good solution may come to the surface. In the meantime the opponents fight combat after combat and Horus usually wins. In the myth, combat scenes follow more than naughty ones. Who will be the favoured by the decision of the Ennead at the end?
We will return to the struggles of Horus and Seth. If this short over-all summary raised your interest, don't forget to check out this site frequently. More coming soon...
Statue of Horus and Nectanebo II. Comparing to Cephren's diorite statue you will spot at the first sight the cahnge in the proportions. By here Horus is the bigger one, and you have to look for the protected pharaoh.
