This volume includes all of the Latin Easter ceremonies transmitted from the Middle Ages and the Early Modern era together with melodies that are currently known to researchers. The compendium offers a unified approach to both melody and text. It includes a total of 375 ceremonies from the 10th through the 17th centuries (and a few more recent offshoots) that originate from many parts of Europe. Each ceremony is individually edited together with a systematic commentary. Frequently, the editing has involved extensive corrections to the findings from earlier research. The findings in the individual commentaries are summarized in extensive surveys on both melody and text tradition. While the editorial research confirms the accepted typology of the ceremonies (Lange, Young, de Boor), the diversity of the findings demonstrates the need to make extensive differentiations within this basic typology. This work is sure to become a fundamental resource for research on Latin Easter ceremonies as well as the melodies from vernacular Easter and Passion plays.
