Cantors made unparalleled contributions to the way time was understood and history was remembered in the medieval Latin West. The men and women who held this office in cathedrals and monasteries were responsible for calculating the date of Easter and the feasts dependent on it, for formulating liturgical celebrations season by season, managing the library and preparing manuscripts and other sources necessary to sustain the liturgical framework of time, and promoting the cults of saints. Crucially, their duties also often included committing the past to writing, from simple annals and chronicles to more fulsome histories, necrologies, and cartularies, thereby ensuring that towns, churches, families, and individuals could be commemorated for generations to come. This volume seeks to address the fundamental question of how the range of cantors' activities can help us to understand the many different ways in which the past was written and, in the liturgy, celebrated across the Middle Ages. Its essays are studies of constructions, both of the building blocks of time and of the people who made and performed them, in acts of ritual remembrance and in written records; cantors, as this book makes clear, shaped the communal experience of the past in the Middle Ages.
