Brunelleschi's Dome


Filippo Brunelleschi, Dome, Exedrae (tribunes), and Lantern for Santa Maria del Fiore, Florence

Speakers: Dr. Beth Harris and Dr. Steven Zucker

in 1418-19, Brunelleschi won the competition sponsored by the Arte della Lana (wool merchants guild) to finish Florence's cathedral (begun by Arnolfo di Cambio in 1296). The principle concern was designing a dome that could span the 140 foot octogonal barrel already built to support it. No dome then existed that was this wide except the ancient Roman Pantheon which spans 142 feet but is made of concrete and is supported on massive walls. In the end, Brunelleschi's ingenious design would allow the lantern above the dome to rise 375 feet above the pavement (the Pantheon's dome is 125 feet high and well as wide) and would be built without the Pantheon's massive walls or the buttressing that medieval architects had relied upon to counter the huge outward thrust created by arches (and domes) of this size.

Key dates:

Brunellschi's dome is the perfect example of the combination of the Romanesque and Gothic styles into Renaissance architecture. Brunellschi's achievement in architecture shows him to be another Renaissance man.
