““Michelangelo, who had already spent much time studying Roman architecture in the ruins, proposed a revolutionary “flying bow bridge” scaffold. It was based on the principles of the Roman arch, whose weight presses out against the sides it is spanning. This ingenious structure could be inserted in just a few small holes made in the side walls, since all its pressure would flow there, and none down to the floor. It would also allow Michelangelo to fresco the ceiling a whole strip at a time, moving to the next strip as soon as one was finished, and thus progressing across the length of the chapel. He got approval to construct it, and it was an instant success, allowing the papal court to have its regular processions under it without any obstruction.””
