She was the only one naked on the stage.
This was the final act of "Lysistrata", a comic play written by Aristophanes about 2400 years ago. This production was put on by the drama department of a mid-sized college, and the limited advertising said the school had taken some liberties with certain details, but the basic premise of the drama remained intact and that the costumes were close to the original.
A few days before the performance, I went to my college library for a modern translation of the play and learned that it was a commentary on both the futility of war and the power of women. I also read that over the years the play was often banned, not so much for onstage nudity but for its anti-war stance and for its threat that women have power over men!
Here's a summary of "Lysistrata" as I saw it:
Once the curtain came up in the large, full auditorium, I became immersed in the history of the Peloponnesian Wars for the first forty-five minutes, setting the background for the final act.
Once the curtain rose on the final act, here's what I saw:
About a dozen male actors cast as ancient Greek warriors are on the left, and a similar number of women as their wives are on the right. The only prop on the dimly lit stage is a large armchair on a low platform at the front center of the stage.
The seat of this throne is eye-level to the other actors. Seated on it is the warrior commander. The footlights illuminate the commander, the rest of the stage is dim.
The warriors are in togas and their wives are in sheer, nearly translucent gowns. Leading up to this final act, the warriors and the wives have been arguing back and forth: The warriors want to continue their wars but are demanding that their wives give them sex, which the wives are withholding until the wars stop. This causes the men to groan in pain with their huge erections. (The 'erections' are prosthetic strap-ons, big cushy phalluses sticking about a meter straight out from each man's toga.)
Desperate as they are for sex, the warriors still don't agree to stop their wars. So Lysistrata, the commander's wife, resorts to summoning "The Naked Goddess of Peace and Reconciliation", or "Peace" for short. A bright spotlight follows the Goddess Peace as she descends to the front center of the stage on a sort of rope swing. She's beautiful and very feminine. Maybe a little older than the other actresses. Gorgeous, as the role requires. She steps off the swing and assumes a goddess-like pose as the spotlight remains on her. Her waist-length long hair is obviously a wig, adding to the other-worldliness of her appearance. Her demeanor is regal and dignified.
Being a goddess with no need for clothing, she is nude. Totally.
The only bright lights are on her naked body, the rest of the stage being lit only enough for us to perceive the other actors moving about.
And since gods and goddesses outrank mortal rulers, she turns toward the throne, motions for the warrior commander to get out of her way, and she climbs up to take his place, the spotlight following her. Seated, she spreads her legs wide and drapes each leg over an armrest. Being close to the front of the stage, her naked body is now lit by both the spotlight and the footlights.
With her body exposed to us, there's no doubt as to the gender of who is now ruling. She maintains this pose for the rest of the play.
In spite of this being just a play, there's a real, live woman sitting there nude, facing the audience. With her legs open. Wide open.
