Romulus was the king of a nation. The point was not the specific story of Romulus being raised by a wolf, but the tradition that the nation was composed of the people who were the survivors of Troy who had journeyed West to the location of Rome where Romulus and Remus were born and where they agreed to found a city. That story appears in numerous Roman histories and was every bit as much a part of Roman collective memory as the story of Exodus was a part of Hebrew collective memory; it was what the Roman people believed.
As I predicted, you will twist and nitpick the actual narrative. When the book is brought to Josiah it is described as a book, nothing more. (Hilkiah identifies it outside the hearing of Josiah.) When it is read to Josiah, the information in it is surprising to him. When he commands that the Passover be celebrated, it is as though it is a new event because the people had not celebrated it for many years. Even if one or two scribes happened to know that the Torah existed, there is no large, commemorated event in the memory of the people. Heck, even you admit that the memory chain was broken because you say that Josiah was brought up in an idolatrous home. Remember your claim in the OP:
Josiah never heard it from his father. That chain was clearly broken, (not that you could ever admit it).
And, of course, there was your second claim in the OP:
This is a bold claim that you have never supported with any evidence of it occurring anywhere except in your imagined reality. Where are such true stories in the examples of the French or the Egyptians or the Chinese or anyone else? When I point out that the Irish, the Dakota, and the Romans all had similar “evidence” that was clearly in error, you start inventing new rules about how many millions of people have to have been a part of this chain of narrative for it to be “proven.”
Sorry, you are just making it up as you go along and your claims have no basis in reality. I have no way to pierce self-delusion, so I doubt that you are going to learn anything from this exchange.
