This collection of essays devoted to the Dominican liturgy in the Middle Ages begins with the reform of ritual and music identified with Humbert of Romans (1200?1277) and proceeds to the cult and liturgy at the shrine of St Thomas Aquinas at Toulouse. Focusing on manuscript examples of local practice, going beyond the liturgy of the friars to include that of cloistered nuns, Dominican penitent women, and lay people, and exploring material elements such as architecture, the essays reflect a more anthropological approach. The volume closes with editions of the oldest known sermons on Thomas Aquinas, probably preached at his shrine in Toulouse. TABLE OF CONTENTS List of Figures AUGUSTINE THOMPSON, O.P.
