Lighting by Appia for ' Tristan and Isolde '
Sketch for the 1923 Milan production of ' Tristan and Isolde' .
Appia endeavored to use a single torch to light the beginning of the 2nd Act. The lighting created a misty, grim atmosphere with the scenery, which was hardly discernible, becoming gradually perceptible as the audience vision adapts to the low lighting level.
