“What we know for sure is that another candidate, a short, homely, and hot-tempered goldsmith named Filippo Brunelleschi, promised to build not one but two domes, one nested inside the other, without elaborate and expensive scaffolding.”
“His dome would consist of two concentric shells, an iounteract …show more content…
He invented a three-speed hoist with an intricate system of gears, pulleys, screws, and driveshafts, powered by a single yoke of oxen turning a wooden tiller. It used a special rope 600 feet long and weighing over a thousand pounds—custom-made by shipwrights in Pisa—and featured a groundbreaking clutch system that could reverse direction without having to turn the oxen around. Later Brunelleschi made other innovative lifting machines, including the castello, a 65-foot-tall crane with a series of counterweights and hand screws to move loads laterally once they’d been raised to the right height.”

Brunelleschi would have to build the dome out of brick, due to its light weight compared to stone and being easier to form, and with nothing under it during construction. To illustrate his proposed structural plan, he constructed a wooden and brick model with the help of Donatello and Nanni di Banco, a model which is still displayed in the Museo dell'Opera del Duomo. The model served as a guide for the craftsmen, but was intentionally incomplete, so as to ensure Brunelleschi's control over the …show more content…
He went to an old Roman city, and looked at their buildings. He realized that to make such a large dome, he needed to make a good support. Looking at the Roman buildings, he had an ingenious idea. He would create 2 domes, and inner one with more heavy materials, and an outer one made of lightweight materials. This way, workers could sit on the inner roof to put in the bricks for the outer roof, and they would also support each other. Finally, he put a ring of timber underneath the whole thing, to make the dome stable. This dome still stands today, and is on top of the Florence
