The size of the proscenium was 24 feet (7.3 m) wide by 21 feet (6.4 m) high (7.3 meters x 6.4 meters). Each scene was hand-painted on linen, which was made transparent in selected areas. A series of these multi-layered, linen panels were arranged in a deep, truncated tunnel, then illuminated by sunlight re-directed via skylights, screens, shutters, and colored blinds. Depending on the direction and intensity of the skillfully manipulated light, the scene would appear to change. The effect was so subtle and finely rendered that both critics and the public were astounded, believing they were looking at a natural scene.
