The Real Da Vinci Code

MILAN, Italy -- The Codex Trivulzianus, one of Leonardo Da Vinci's oldest notebooks, is out from under lock and key, offering the world a rare look into the mind of a genius. Normally hidden away in a library at Sforzesco Castle and reserved for scholars' eyes, the 55-page collection of sketches and writings is on public display for the first time in nearly a decade. It includes character studies, drawings of church domes and military machines, and even a self-improvement guide. For all the larger-than-life ideas it contains, the Codex Trivulzianus is actually quite small. It measures 8 inches by 5.5 inches -- about the size of an average paperback -- and looks every bit its 519 years old. [More]
