Despite eye-opening discoveries, exhibitions, and performances, many valuable artefacts and documents of the performing arts continue to linger in oblivion. How do these sources affect our understanding and appreciation of the theatrical past? Which challenges and opportunities arise from their reuse in modern contexts, museal and non-museal? Theatrical Heritage addresses these and related issues from a broad perspective. In accessible essays written by theatre and music scholars, performers, directors, conservators, and administrators from Europe and the USA, new methods are advanced to reactivate the theatrical past.
