When you think of the story of Brunelleschi's dome of Florence cathedral, you think of complicated construction machinery and mind-boggling mathematical calculations, don't you? Well, you're right. The story is rife with math and machines. But, it's also spiced with plenty of anecdotes, the kind that run the gamut of human strengths and foibles. They've been in circulation since the Renaissance, and they're still, even after more than five hundred years, guaranteed to appeal to young and old audiences alike. Surprisingly, these anecdotes were long trapped between the pages of scholarly books, until Ross King released them a few years ago in his popular adult non-fiction book Brunelleschi's Dome. What was still missing, however, was an accessible children's version of the Brunelleschi story. Decades ago Anne Rockwell wrote and illustrated Filippo's Dome, but her book is long out of print.
