Conceived and directed by Robert Wilson, this was an adaptation of the tragedy by Euripides, with text written by German playwright Heiner Muller. The setting was based on the landscape surrounding Delphi in Greece. A 50 foot wide bas relief mountain ridge sits on top of a raked performance area bisected by a river. Through the course of the performance, the landscape underwent a transformation with changing elements indicating the passage of time and historical epochs. The mountain erodes, shedding boulders into the field below. At the performance’s climax, a light from heaven cuts a hole in the mountain, revealing the horizon beyond. The play was produced by American Repertory Theater in Cambridge, MA.
