And at the centre of this new age, was the multi-talented artist and inventor, Leonardo da Vinci, the ultimate Renaissance man.

In this episode of Mystery Files, a team of Renaissance and Leonardo experts investigate the truth to the claims that Leonardo was a genius inventor, and use science to prove that he really was probably the greatest artist to have ever lived.
