No, Andrew Lloyd Webber is not bringing Dan Brown's mega-hit to the stage (Midnight / all alone in the Louvre / whats this on the painting? / I'm being shot at again... hmmm... it could work). Actually, it seems that Da Vinci himself may have been the composer of a hymn hidden within The Last Supper. This is just incredible:

Pala first saw that by drawing the five lines of a musical staff across the painting, the loaves of bread on the table as well as the hands of Jesus and the Apostles could each represent a musical note.

This fit the relation in Christian symbolism between the bread, representing the body of Christ, and the hands, which are used to bless the food, he said. But the notes made no sense musically until Pala realized that the score had to be read from right to left, following Leonardo's particular writing style.

Interestingly, this story follows one of another hidden musical composition, also linked to an element of Dan Brown's story. The Roslyn Motet is a hidden musical score found in the architecture of the Rosyln chapel.

You can hear the hymn by clicking here. Its not the most fascinating 20 seconds of music in the world, which makes me wonder if its just a code for a bigger mystery...

Maybe it would help to get a close-up look at those notes, you can check out the remarkably high definition, 9 gigapixel image of The Last Supper at Haltadefinizione.

Or maybe I've read too much Dan Brown?
