The primary architect of the Italian Renaissance is often considered to be Filippo Brunelleschi. He was instrumental in introducing linear perspective to art, revolutionizing the way space and depth were represented in paintings and architecture. Brunelleschi is best known for designing the dome of the Florence Cathedral, an engineering marvel of its time that showcased his innovative techniques. His work laid the foundation for future Renaissance architects and artists, influencing figures like Michelangelo and Leonardo da Vinci. The Renaissance, characterized by a renewed interest in classical antiquity, was marked by significant advancements in art, science, and humanism largely due to the contributions of Brunelleschi and his contemporaries.
