This episode continues to examine the construction history of Brunelleschi’s great Renaissance-style church. Based on extraordinarily detailed archival records regarding the construction of the church over nearly a decade, we are able to paint an incredibly vivid picture of how, literally, brick by brick and column by column the church was built. We also discuss some of the most important deviations made from Brunelleschi’s original plan and identify those historical figures who were responsible for them.
