A visionary avant-garde director and inventor of the theater of the 20th century - Adolphe Appia saw his vision come to life at its best in Wagner’s operas. In the abstract and mythological landscape of Der Ring des Nibelungen, Appia is sculpting spaces of light, shadow and time, a universe that mixes pagan with the hyper-modern. In one defining moment of theater, the stage becomes a place of contemporary art.
