Michelangelo Code?

SAO PAULO, Brazil (Reuters) - Two Brazilian doctors and amateur art lovers believe they have uncovered a secret lesson on human anatomy hidden by Renaissance artist Michelangelo in the Sistine Chapel's ceiling. Completed nearly 500 years ago, the brightly colored frescoes painted on the Vatican's famous sanctuary are considered some of the world's greatest works of art.

They depict Biblical scenes such as the "Creation of Adam" in which God reaches out to touch Adam's finger.
But Gilson Barreto and Marcelo de Oliveira believe Michelangelo also scattered his detailed knowledge of internal anatomy across 34 of the ceiling's 38 panels. The way they see it, a tree trunk is not just a tree trunk, but also a bronchial tube. And a green bag in one scene is really a human heart.

The key to finding the numerous organs, bones and other human insides is to first crack a "code" they believe was left behind by the Florentine artist. Essentially, it is a set of sometimes subtle, sometimes overt clues, like the way a figure is pointing. "Why wasn't this ever seen before? First, because very few people have the sufficient anatomical knowledge to see these pieces like this. I do because that's my profession," said Barreto, who is a surgeon in the Brazilian city of Campinas.

Eventually Barreto and Oliveira came to believe Michelangelo had left behind coded messages in each panel to help viewers find the hidden body part.

Their proposals, he said, "stretch the visual evidence far beyond Michelangelo's own specific vocabulary of poses, gestures and symbolic relationships."

Indeed, why would Michelangelo hide drawings of human organs in the Sistine Chapel? Barreto and Oliveira say they aren't sure, but it is well known that Michelangelo and other Renaissance artists were obsessed with human anatomy and the human body. There are also other examples of artists "hiding" objects in their paintings, images that can only be seen from a certain perspective.

Still, the two doctors have sent their book to art historians and anatomical specialists in Portugal to get their opinion, and plan to eventually get the Vatican's opinion too.

"We're not here to play around. We believe this is a great discovery for the arts," Barreto said. "The only thing we want to do is spread this knowledge."
