Well, I've been reading The Feud that Sparked the Renaissance and was amazed to find that some machines commonly atttributed to the inventor Leonardo da Vinci were actually invented by an artist from Florence, namely Filippo Brunelleschi, who was an architect, goldsmith, inventor, artist, and so on. While this information is probably quite commonly known, it came as a great suprise to me.
I have so much to write of and so little time to do it!
