As I recall from the Nova special on this on PBS a few months back, experts are pretty sure Brunelleschi used a series of ropes from the floor (similar to the first theory examined in this video), making some of this seem a bit dated.  But nonetheless a great peek into the genius of the man who made one of the world’s great structures a possibility.

We have many tours lined up for this fall, but still have some openings–come see it with us!
