Theatre has engaged with science since its beginnings in Ancient Greece. The intersection of the two disciplines has been the focus of increasing interest to scholars and students. The Cambridge Companion to Theatre and Science gives readers a sense of this dynamic field, using detailed analyses of plays and performances covering a wide range of areas including climate change and the environment, technology, animal studies, disease and contagion, mental health, and performance and cognition. Identifying historical tendencies that have dominated theatre's relationship with science, the volume traces many periods of theatre history across a wide geographical range. It follows a simple and clear structure of pairs and triads of chapters that cluster around a given theme so that readers get a clear sense of the current debates and perspectives.
