Now you see it: forgotten magic manual contains original da Vinci code - World: "AFTER lying almost untouched in the vaults of an Italian university for 500 years, a book on the magic arts written by Leonardo da Vinci's best friend and teacher has been translated into English for the first time.

The world's oldest magic text, De viribus quantitatis (On the Powers of Numbers), was penned by Luca Pacioli, a Franciscan monk who shared lodgings with da Vinci."
