Filippo Brunelleschi: The Genius of Good Design 8/15/20151

Santa Maria del Fiore (the Duomo) 8/15/20152 Dome by Filippo Brunelleschi, Began 1296, for over 100 years, the Dome remained unfinished. The original builders of the cathedral in 1296 even left writings hoping that God would offer a solution because they did not have one.

Filippo Brunelleschi was the answer to their prayers. 8/15/20153 In 1420, the dignitaries of Florence held a competition offering the enormous prize of 200 gold florins to the architect whose genius could span the unfinished dome of the Florence Cathedral.

From Sculptor / Goldsmith to Architect: Little is known of Brunelleschi's life. We do know that Brunelleschi studied the Ancient Roman Ruins with fellow Artist Donatello. 8/15/20154 The Pantheon Roman Aqueducts

8/15/20155 Taking the egg graciously, he gave one end of it a blow on the flat piece of marble, making it stand upright. Rather than presenting a traditional model, Brunelleschi simply proposed, “Whosoever could make an egg stand upright on a flat piece of marble should build the Dome, since thus each man's intellect would be discerned.” When none of the Masters could find a way, Brunelleschi, was told to make it stand.

8/15/ The craftsmen protested that they could have done the same; but Brunelleschi answered, laughing, “Yes, and they also could have raised the Dome, if they could have only seen the design.” And so it was resolved that he should be commissioned to carry out this work. Note: If you interlock your fingers and try to squeeze an egg lengthwise to break it, you'll find that it can withstand more force than you might expect.

Dome Geometry 8/15/20157 As the dome rises, the necessary slant of each new layer's surface can be found by generating a cone whose apex is located where the dome's centerline intersects the radius of the wall's arc.
