Just like Mr. Tom and I ask you to revise your work and to do first drafts of your work, Filippo Brunelleschi and made rough drafts of his dome that changed the world.

The Cathedral’s Museum has models that Brunelleschi built to practice and try out his new ideas as well as some of the tools and machines that were used to construct the actual dome. Cool stuff!
