This study traces the origins of Hebrew prayer among the Jews and explains how the first volumes of formal Jewish liturgy emerged. It describes in a lively and thought-provoking manner the leading rites and personalities of medieval Jewish worship and explains how the various interpretations of Judaism in the modern world have responded in their own way to the challenge of dialogue with the divine. Existing theories are challenged and new theories offered, and the result will make liturgical research accessible to modern readers. (PUBCambridge)In softcover!
