What is the discipline in which ‘academic drama’ is engaged? Leaving aside debates about an emphasis on theatre or performance as the key term, who is included in the discipline, and how has it reshaped itself over the last decades? Is it right to say there have been major redefining changes, and if so, what are they? Graham Ley is Emeritus Professor of Drama and Theory at the University of Exeter. He has published widely on ancient Greek performance and comparative theory, and is currently preparing an essay on a theoretical history for Greek tragedy. He has previously published in New Theatre Quarterly on developments in Australian theatre (1986), the avant-garde (1991), Peter Brook (1993), Diderot (1995), Tara Arts (1997), and most recently diaspora theatre in the UK (2011). The present discussion is adapted from the conclusion to Ancient Greek and Contemporary Performance, a collection of essays to be published later in the year by the University of Exeter Press.
