High in the Caucasus at the ends of the earth, Prometheus is chained to a rock with a bolt through his chest. He talks of a secret that should not be told for fear of its power being lost. This secret is so important that its secrecy could be our salvation. _Prometheus Bound_ is a play veiled in myth, but as unearthly as the play seems it presents the human condition in a more uncomfortably naked state than any other play. Linguistically and thematically it is the most sophisticated and brutal of all the tragedies. On the page it invites deep analysis but on its feet it becomes the very thing that theatre should be: a journey to the heart.
