I once heard that in the original handwritten score of the first movement of Beethoven's 9th symphony there are references to the creation myth as annotations. However, these were not replicated in later copies and can only be found in the original manuscripts in the Beethoven Haus in Bonn.
This would fit the tone of the music (starting of very light and then suddenly exploding etc.). However, I can't find any reference to back this story up, so I might remember it incorrectly or it was just a myth. Can somebody conclusively confirm or deny this story? If this is true, it would be great if there were some reference anywhere, which parts of the first movement correspond to which parts of the creation myth.
