Whose body do scientists want to dig up?
 The legend of Leonardo da Vinci is covered in mystery: How did he die? Are the remains buried in a French castle really those of the master? Was the "Mona Lisa" a self-portrait in disguise ? 

A group of Italian scientists believe the key to solving those puzzles lies with the remains, and they say they are seeking permission to dig up the body to conduct carbon and DNA testing.
