The drama of the English Middle Ages is perennially popular with students and theatre audiences alike. This book provides an authoritative introduction and an up-to-date, illustrated guide to the mystery cycles, morality drama and saints' plays which flourished from the late fourteenth to the mid-sixteenth centuries. The book emphasises regional diversity in the period and engages with the literary, and particularly the theatrical values of the plays. After a general introduction there are chapters devoted to each of the major regional cycles, the less-well known East Anglian and Cornish traditions, the morality drama and saints' plays. Two illustrated chapters are devoted to the performance of medieval plays, in their own time and in recent modern revivals. A full reference section includes a guide to scholarship and criticism, an extensive classified bibliography and a chronological table.
