I know what you're thinking, what does The Vagina Monologues have to do with quartos and the theatre of 1599? Honestly, not a hell of a lot, but the way we're rehearsing it does. Tiffany Stern has posited (in her excellent Making Shakespeare) that the actors of Renaissance London would be left largely to their own devices to learn their roles. They might occasionally meet with a director (Stern uses the term "instructor") to discuss what they were going to do on stage, but would typically only rehearse together once or twice. That's how we're rehearsing Vagina Monologues.
I, for one, am eager to see how this experiment in Shakespeare's original rehearsal conditions plays out. I'll be sure to keep you posted on that and other developments.
