Summary
This episode explores the centuries-long construction of the Florence Cathedral, focusing on the engineering challenge of its massive dome. It details how Filippo Brunelleschi won the 1418 competition against Lorenzo Ghiberti and devised a self-supporting herringbone brick pattern to avoid wooden scaffolding. The story highlights Brunelleschi’s innovative machines, including the first patent in history, and his rivalry with Ghiberti. Later chapters cover Michelangelo’s criticism of the unfinished base and the cathedral’s evolution into a symbol of civic pride.
