Status Updates From Brunelleschi's Dome

There is indeed something miraculous about the sight of the dome regardless of where it is viewed from whether close up or far away. The fact that it was built by men and built amid war and intrigue with only a limited understanding of the forces of nature only makes it more of a wonder.

People did not believe possible - a polygonal dome can be constructed without a wooden support network only if a true circular one is contained within its thickness.
