Reflecting the range of their honorand's interests, the essays in Ritual, Text and Law provide a stimulating and panoramic exploration of the interrelated fields of liturgy and canon law in the Middle Ages, chiefly through the scrutiny of texts and their transmission. Roger Reynolds' scholarly work has not only considered the relations between law and liturgy, but has also focused on liturgical practice and the evolution of rituals, paleography and the often complicated relationships between canonical collections, in particular the southern Italian Collection in Five Books. Due in large part to Reynolds' research, the fields of medieval canon law and liturgy are now recognized as fundamental elements of medieval religious and intellectual history that shed light on medieval Christian belief and practice. The studies are grouped thematically under the headings of 'Ritual' and 'Text and Law'. Each section has an introduction by the editors, in which they survey recent developments in the study of medieval canon law and liturgy with reference to Reynolds's own research, provide historical context for the individual studies, and draw attention to the ways in which the studies reflect current concerns. Individually, the contributors offer new viewpoints on key issues and questions relating to medieval religious, cultural and intellectual history, particularly of the period c.900-1200, and especially the Italian peninsula. Collectively they illuminate the interaction of medieval Christianity and its rituals, as well as the relationship of the secular and the sacred as transmitted in liturgico-canonical texts from the time of the early church to the 14th century.
