Final answer:
Brunelleschi used an octagonal dome shape, new methods of hoisting stone, and radical masonry techniques in his dome of Florence Cathedral.
Step-by-step explanation:
Brunelleschi used several innovations in his dome of Florence Cathedral. Firstly, he designed an octagonal dome shape, which was a departure from the traditional round domes. Additionally, he used new methods of hoisting stone, creating and using numerous hoisting machines to lift the materials to the workers. He also implemented radical masonry techniques, such as a double-walled system from lightweight bricks laid in a herringbone pattern, which allowed the dome to rise higher and more substantially. However, there is no mention of inventive pilasters being used in Brunelleschi's dome.
