The Magic of Illusion—presented here in a seven-part podcast series—is a film about how we see, what we see, or what it is we think we see. Al Roker guides us on a journey into the secrets of illusion, utilizing special effects to illustrate the artistic and visionary discoveries of the Renaissance. While Copernicus and Columbus were changing our understanding of the world, the Renaissance masters were dramatically changing the way we see that world. The film uses recent technology to look at old works in new ways. Each segment of this podcast presentation unlocks new secrets of illusion and perspective as seen in the works of old masters. This program was made possible by The Arthur Vining Davis Foundations. In 1427, inside Santa Maria Novella, Florence, Masaccio created the masterpiece The Trinity using linear perspective for the first time. This segment explains how he was able to make the wall behind the work seem to disappear so that the painting becomes an extension of the room in which the viewer stands.
