Book excerpt: First published in 1993. Part of a series on medieval casebooks, this volume six looks at the Chester Mystery Cycle Play manuscripts and comparisons of the York and Chester Cycle. Theologically a product of the Middle Ages, historically a product of the Renaissance, what we today call the Chester Mystery Cycle is a series of twenty-four plays dramatizing the events of salvation history from Creation until Doomsday. One of four surviving English mystery cycles, the Chester Cycle, which originally included a twenty-fifth play of the Assumption surpressed sometime in the mid-sixteenth century, was, until more modern times, last performed in 1575.
