Brunelleschi vs Michelangelo: should a dome be engineered or dreamed?

I built without scaffolding from below, without centering, brick by herringbone brick—my dome stands because I solved it, not because I felt it.

And yet you left me the sculptor's task: a dome must rise like a living body, its ribs the muscles of the sky, not merely a sum of masonry.

Beauty that ignores its own weight comes crashing down, Buonarroti; I gave Florence a miracle that would not fall.

But Rome I gave a soul—and men look up not to admire your arithmetic, but to feel themselves standing beneath God.
