During the early years of the Medici dynasty, Florence has a domeless cathedral. Its original builders - alas! - had been too ambitious.
Growing up in the shadow of the unfinished cathedral, Cosimo de Medici wonders if his family could hire someone capable of finishing the project.
In the same city, a maverick architect with fresh ideas - Filippo Brunelleschi - is trying to make his way. Not worried about Filippo's temper, Cosimo and his father, Giovanni, back him.
Using designs not seen for a thousand years, Brunelleschi creates new buildings. Florentines are so entranced, they visit work sites just to see a style they've never seen before. Cosimo and Brunelleschi set out to rebuild a city which could rival Rome.
Cosimo wonders: Could his new architect create a dome befitting the unfinished cathedral in Florence? Although it isn't easy to convince the city's decision-makers, Brunelleschi wins the contract.
But ... can he actually create the vision he sees in his mind? What rules of architecture will he follow, to build what no one has built for a thousand years?
