Claim: Horus was called “Iusa”, the “ever-becoming son” and the “Holy Child”. Truth: No one in Egyptian history was ever called “Iusa” (the word does not exist) nor was anyone called “Holy Child”.
Claim: Horus came to fulfill the Law, and was supposed to reign one thousand years. Truth: There was no Egyptian “law” for Horus to fulfill, and there is no mention of a thousand year reign in Egyptian mythology.
