Leonardo. Laughing at us from the grave.

So, apparently, Leonardo Da Vinci was really into codes. It seems everyone these days is picking something out of his work. Dan Brown apparently missed something when he was finding secrets in Da Vinci's Last Supper.

It's a new Da Vinci code, but this time it could be for real. An Italian musician and computer technician claims to have uncovered musical notes encoded in Leonardo Da Vinci's "Last Supper," raising the possibility that the Renaissance genius might have left behind a somber composition to accompany the scene depicted in the 15th-century wall painting.

"It sounds like a requiem," Giovanni Maria Pala said. "It's like a soundtrack that emphasizes the passion of Jesus."

Painted from 1494 to 1498 in Milan's Church of Santa Maria delle Grazie, the "Last Supper" vividly depicts a key moment in the Gospel narrative: Jesus' last meal with the 12 Apostles before his arrest and crucifixion, and the shock of Christ's followers as they learn that one of them is about to betray him.

Pala, a 45-year-old musician who lives near the southern Italian city of Lecce, began studying Leonardo's painting in 2003, after hearing on a news program that researchers believed the artist and inventor had hidden a musical composition in the work.

"Afterward, I didn't hear anything more about it," he said in an interview with The Associated Press. "As a musician, I wanted to dig deeper."

In a book released Friday in Italy, Pala explains how he took elements of the painting that have symbolic value in Christian theology and interpreted them as musical clues.

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.

And apparently there's something to this one.

Alessandro Vezzosi, a Leonardo expert and the director of a museum dedicated to the artist in his hometown of Vinci, said he had not seen Pala's research but that the musician's hypothesis "is plausible."

Vezzosi said previous research has indicated the hands of the Apostles in the painting can be substituted with the notes of a Gregorian chant, though so far no one had tried to work in the bread loaves.

Having never really looked at the Last Supper very closely until now, the table looks like the results of a bun fight at a mess dinner in Devonport. Not one bun is on a plate, despite the fact that there appears to be 16 plates on the table. Pala may be on to something.

I'm waiting to see what Pala comes up with when he puts a musical staff across the spots on one of these. I'm guessing Queen.

Arrr... thank ye Cap'n.
