The medieval Mysteries are, above all, wonderful stories involving families at work and play, all in relationship to an idea of a God who was not walled up in church to be visited only on Sunday but who was ever-present. Mr. Sahlins has adapted these stories to make their language available to a present-day American audience, preserving the verse in all its alliterative beauty while replacing medieval and regional words. The resulting play is joyous, suspenseful, and satisfying, an unusually engaging drama for all ages.
