The monastic archive is not only a repository of texts, rules, and institutional memory, but also a space of resonances in which sound, silence, and repetition shape the very conditions of remembrance. This research project approaches that archive through the figures of Kassia, Hildegard of Bingen, and Herrad of Landsberg, whose works emerge from distinct yet interconnected monastic environments across Byzantine and medieval Latin worlds. Through Kassia’s hymnographic compositions, Hildegard’s visionary chant and sonic cosmology, and Herrad’s encyclopedic Hortus deliciarum, the project reads the archive not as a stable depository of preserved knowledge, but as an acoustically and materially charged field in which forms of inscription, transmission, and recollection are continuously shaped. Attending to these monastic soundscapes makes it possible to rethink the archive as a site of deeper intertwined realities, where textuality and sonic practice co-constitute the conditions of memory and thought.
