Bosch's 600 year old butt-music from hell

Robbo writes, "My friend, SF author J.M. Frey, posted this curious thing she found where a detail in Hieronymus Bosch's painting 'The Garden of Earthly Delights' features musical notation inscribed on some dude's ass. Of course, someone has taken the time to transcribe these notes and have now presented to the interwebs a piano interpretation of the 600 Year Old Butt Music From Hell of Hieronymous Bosch. Feel free to gavotte along."

Luke and I were looking at Hieronymus Bosch’s painting The Garden of Earthly Delights and discovered, much to our amusement, music written upon the posterior of one of the many tortured denizens of the rightmost panel of the painting which is intended to represent Hell. I decided to transcribe it into modern notation, assuming the second line of the staff is C, as is common for chants of this era.
