Probably not of Nazareth (you might want to read UriYosef's article). BUT I think is possible that a man existed who became a myth. I think it just as likely that he didn't -- just as Mith-ras and Dion-ysius never existed. The fact that James, who called himself "Jsus' brother" probably DID exist doesn't mean that Jsus did as that term was used very loosely. . .
