A primary focus of this book is on the impact of time and memory as they intersect and constitute the spaces of theatre. These spaces include more traditional sites of theatre, such as those involving stages and curtains, actors and audiences, as well as those other theatres or spaces of performance that range from performance and installation art, to the performance of a string quartet, and from the writing of performance, to the performance of writing. What unites them is the presence of time as the constant and corrosive agent of theatrical absence, a vanishing site that finally affirms these theatres as theatres of thought, as spaces of thoughtful and mirroring reflection.

With such time in mind, attention is directed toward theatre's own blurred and porous boundaries and, implicitly, that most conventional theatrical form, the proscenium itself, evoking questions such as: where does the performance begin and where does it end? Who is watching and who is being watched? And what, as time takes its toll, is there to be seen at all? For it is from this demarcating line of representation that - like a 'line in the sand' - such spaces of thought, theatrical or not, largely determine where the various forms of representation begin and end, where time is told of others, and where time is finally told of each of us.
