Detailing how rivals Brunelleschi and Ghiberti had to collaborate when building the dome of the Florentine Duomo, Walker explores the world of 15th century Florence and all its various artisans and political leaders. The author explores the highs and lows of Brunelleschi’s and Ghiberti’s relationship and how, despite their feud, both artists were able to build – both literally and metaphorically – the foundations of the Italian Renaissance.
