Preview | Leonardo, The Man Who Saved Science
Leonardo da Vinci is well known for his inventions as well as his art. But new evidence shows that many of his ideas were realized long before he sketched them out in his notebooks — some even 1,700 years before. Was Leonardo a copycat?
The Vitruvian Man
During the Renaissance, the goal of art was the expression of harmony, and harmony is a matter of proportion. Leonardo was fascinated with proportion. Vitruvian Man is a pure expression of the Renaissance – a secular, almost carnal figure whose reach extends to the very limit of the cosmos.

Leonardo’s illustrations, as precise as his technical drawings of machines, were unequalled in accuracy until the photographic techniques of the 19th century.
