剧情简介 《Great Cathedral Mystery》是2014年的一部其它片。由David Murdock精心打造的，电影From PBS :The dome that crowns Florence’s great cathedral of Santa Maria del Fiore—the Duomo—is a towering masterpiece of Renaissance ingenuity and an enduring source of mystery. Still the largest masonry dome on earth after more than six centuries, it is taller than the Statue of Liberty and weighs as much as an average cruise ship. Historians and engineers have long debated how its secretive architect, Filippo Brunelleschi, managed to keep the dome perfectly aligned and symmetrical as the sides rose and converged toward the center, 40 stories above the cathedral floor. His laborers toiled without safety nets, applying novel, untried methods. Over 4 million bricks might collapse at any moment—and we still don’t understand how Brunelleschi prevented it. To test the latest theories, a team of U.S. master bricklayers will help build a unique experimental model Duomo using period techniques. Will it stay intact during the final precarious stages of closing over the top of the dome?

oohgrape 说：不停地暂停回放总算是看懂了。布鲁内莱斯基可以做到不使用内部支架完成穹顶，主要依靠1. 鱼骨式的砖块堆砌方式；2. 以地面上花朵状框架的弧形为辅助，使南瓜顶的每一面的堆砌面都呈现稳定的倒拱形。有动画的辅助，穹顶实物和穹顶模型的相互映照相互验证，技术手段讲解得很清晰。
小车 说：介绍其实还是比较简略的，集中在介绍鱼骨结构的基本原理上面。介绍和做一个小穹顶模型同步进行，不涉及当年的历史以及克服的困难。单纯从本片角度讲，是很单薄的。不过结合《圆顶的故事》，通过影像资料把书里面没说清楚的地方详细展开了，所以我打四颗星。
谣言rumors 说：nova做的真是是精品，讲圣母百花讲的很好，专注于极具震撼的圆顶的工程学实现和背后的故事。可惜那个模型最后也没见它完工
