By the entrance of the first hall, a large panel depicts the life and works of Leonardo in the contexts of the history, the culture and the society of his times. But our attention is already turned to the models of Leonardo?s machines: from military machines to building-construction machines, to instruments for scientific use. We find 18 of them in the first hall and 22 in the second, each presented and described with precise reference to Leonardo's drafts and notes.
It is a large heterogeneous collection which can also be appreciated for its expository value.
