What inspired Brunelleschi's geometric style of architecture?

Brunelleschi's geometric style of architecture was inspired by a revival of classical Roman principles, emphasizing symmetry, proportion, and mathematical clarity. His study of ancient ruins and the application of linear perspective significantly influenced his designs, allowing for a more rational and harmonious aesthetic. Additionally, his innovative use of geometry in structural engineering, particularly in the dome of Florence's Cathedral, showcased a blend of artistic vision and technical mastery that defined the Renaissance.
