My Prometheus Unbound (by scenic restrictions of the Greek era)

When I read the Overture of Prometheus Bound, I imagined the stage to be in blackout; of course, this might not coincide with the Greek theatre since it had to use natural elements in order to convey the scene and lighting was not necessarily an option. I feel, however, that in my version of Prometheus Bound, the lights would be off, allowing the audience’s complete attention to be on the words, the story that the chorus tells of Prometheus. It is a very sharp way of beginning the play; it really carries the audience into the spiritual aspects of this play. There is a stark, almost desperate, awareness in the dark. Nothing is as important, in this moment, than the words spoken from anonymous lips. Also, it is beautifully written, therefore I would prefer the focus to be on this first dialogue.
The first light would show to us Power, Violence, Hephaestus, and Prometheus- being dragged- walking towards a rock. From here on out, the set would be quite minimalist. All that would be needed, permanently, is the rock to which Prometheus is bound, and perhaps a raised platform for the Chorus. I like the idea of the Chorus being raised because I imagined them as floating and high. They look down at Prometheus –perhaps not symbolically but literally- since they are free and he is not. They can choose to move up and down from the platform, they can explore all levels.
Another major movement in the set is the entrance of Ocean with his chariot. I’m fairly certain that the Greeks used real horses, and I would like to keep to this. It gives Ocean a much louder and imposing presence with real horses, and it also reminds us of other living creatures in theatre other than humans. There are other living creatures in life, and theatre is a reflection of life.
The hardest event to imitate would be the storm wrought upon Prometheus by Zeus. I can see drums being used to imitate thunder, and I imagined perhaps small patches of fire (contained, I’m sure) to indicate that lightning had struck. Perhaps we could ask the audience to open and shut their eyes continuously, as though the sky were getting light than dark very suddenly. Just joking. I don’t know, I’ll figure that part out later.
The last important scene event would be the Chorus’ exit; this is a very subtle exit. When I read that part, I instantly pictured the scene in Disney’s Alice In Wonderland of Alice crying and all the strange animals and birds of the dark forest sort of fade away as they cry with her. I imagine the Chorus to sort of fade away as well, as they weep with Prometheus; this of course, could be done with lighting, which would eventually completely fade out on the Chorus, leaving only a dark remain. However, if we were technologically limited, maybe we could have each one of the female members leave, one by one, discreetly, until they were all gone before the play ended. And then the play would end in blackout, just as it started.
