There was an original story.Whether it was true or not, whether anyone now knows what it is or not (thanks to morons keep chaging it) is completely irrelevant, and largely proves the point that making such changes simply creates a complete mess of the "franchise", as well as smacking original fans in the face as no longer "good enough".
Actually, no, there's not. Most old stories that were written down in one form or another were synthesis of many stories or aspects of many characters. Such is the nature of folklore, mythology and storytelling.
