“From the Vault of the Heavens”
Filippo Brunelleschi was the mathematician and artist who designed the dome of S. Maria Novella in Florence. How much maths did Brunelleschi know? Did he know about astronomy, and could he use an Astrolabe ?
I was able to find a paper mapping his friendships with local mathematicians and astronomers and astrolabe dealers using the new Google Scholar search engine that indexes academic reference material. Using Google Scholar can be frustrating as the search engine indexes cloaked content – content you have to pay to index. But at least you can find the publication details of likely articles.
