In order to illuminate the role written documents played within medieval monastic life, this project takes as a case study the monastery of Cluny and some associated houses during the central Middle Ages. I approach these documents as signs, drawing on anthropological and philosophical work on semiosis, and as media technologies, using history and cultural studies centered on orality and literacy, and conclude that the monastic use of texts was essentially ritual, and as such exerted an important influence on the development of literacy as a tool and a set of practices. Nor did this influence flow in just one direction: as monastic ritual transformed the use of documents, the use of documents also transformed monastic ritual.

To study the relationship between document and ritual, I examine what medieval documents reveal about their production and use. I also read the sources for what they directly report about the nature of monastic life and monastic ritual, and the specific roles various documents played within these contexts. Finally, these accounts of changing monastic scribal and ritual practice are laid alongside a third—that of what the monks themselves actually enunciated, both directly and indirectly, about their own understanding of semiosis and its operation in their lives.

Ultimately, my dissertation connects valuable theoretical and philosophical work on ritual, semiosis, and orality and literacy with manuscript studies and with a wide range of recent historiography on the complex transformations remaking society inside and outside the cloister during the Middle Ages. It thus serves to bring these disparate yet mutually indispensable lines of inquiry into better contact with one another. And in this way, it approaches an understanding of human sign-use, carefully rooted in both material and institutional culture, during a key period in the history of human civilization.
