Ep. 37: The Secret of Florence's Dome

Ep. 37: The Secret of Florence's Dome

Author: Danielle Oteri April 7, 2026 Duration: 39:42

Every day, every single tour guide in Florence tells thousands of tourists a story that is not true. It’s the story of the construction of the dome, a feat of engineering so ingenious that even today, architects and engineers can’t understand how it was done, achieved by one single man, a goldsmith with no formal training.

But Filippo Brunelleschi’s innovation — a double-shell dome built with herringbone masonry — had been used to build mosques and mausoleums in Iran. And 15th-century Florentine merchants, who had large networks and communities in Iran, particularly Soltaniyeh, were no doubt very well acquainted with them.

In this episode, I’m discussing this incredible story with Massoud Katebeh, an Iranian-American engineer who studied in Florence. We are both fascinated with the story of Piero Sanpaolesi, the professor who first revealed these Persian models for the dome of Florence in 1971, and was ignored.

Now, a new generation of scholars, in particular Dr. Lorenzo Vigotti and Prof. Hadi Safaeipour, is building on Sanpaolesi’s groundbreaking research and adding brilliant new insights.
