Even as Copernicus and Christopher Columbus were challenging our understanding of the globe, Renaissance artists were transforming how we see that world. Al Roker hosts this journey into the secrets of illusion, using special effects and cutting edge graphic technology to explore how linear perspective was put to brilliant use by such figures as Masaccio, Leonardo da Vinci, Albrecht Dürer, Piero della Francesca, Andrea Mantegna, and Hans Holbein the Younger. Crisscrossing Europe, this engrossing program highlights masterworks found in galleries and museums, monasteries and cathedrals, concluding with a look at Andrea Palladio's Teatro Olimpico, a Roman-style theater that made innovative use of lighting.
