The Rochester Museum and Science Center has mounted a comprehensive exhibition of the work of Leonardo Da Vinci. 'Da Vinci - The Genius' gives us a peek into the mind of an inherently curious man. A man who worked to further his understanding of the world around him and who built the foundations of much of what we know today. From civil and military engineering, to anatomy and, yes, art. The world famous Mona Lisa painting has a special place in this exhibit and we had the opportunity to sit down with Mona Lisa expert, Pascal Cotte, to learn some of the secrets of the painting.
