Leonardo da Vinci, one of the most extraordinary thinkers in history, sketched and wrote about many innovative machines that were hundreds of years ahead of their time but were never built during his lifetime. Now, in this remarkable book, readers are presented with five of his most famous inventions, realized as 3-D pop-ups with moving parts. Each reimagined invention is accompanied by text and illustrations drawn from da Vinci's personal journals, providing insight into the ideas and visions of this Renaissance genius.
