When we first arrived there we examined his "Vitruvian Man". This painting is an example of the golden ration. His arm spam was the same of his height. Each item of his body was proportionate of another part.
Other inventions that we got to see was "Meccanism d' Orologio" which was a clock without batteries, "Ornitotteio Verticale" Vertical flying machine, and "Ponte Salcatico" emergency bridge. This is his bridge --->Another of his paintings that we observed was the "Mona Lisa"
