Libraries weren’t only for books — in some medieval monasteries, ashes from saints’ relics were catalogued like manuscripts.

A Monastery Kept More Than Books

A medieval monastery’s library was part of a larger world of stored knowledge and sacred objects. Books might sit in a library, while relics—physical remains of saints or objects associated with them—were commonly kept in reliquaries, containers designed to protect and display them. The two collections were not necessarily on the same shelves, but monks could document both in written records.

Why Record Bones and Ashes?

A relic was not simply an unusual possession. Christians regarded a saint’s remains as a tangible connection to a holy person, and churches and monasteries preserved them for veneration. A written inventory could identify what an institution claimed to hold, describe its container, and help keep track of valuable objects. Cataloguing made a spiritual collection legible and manageable, much as a book list did for texts—though the objects served different purposes.

Reading and Remembering

For monks, learning involved more than reading. Manuscripts preserved teachings and accounts of saints; relics gave those accounts a physical focus. The distinction between a library and a treasury mattered in practice, but both depended on careful preservation and record-keeping. In that sense, a monastery’s archive could unite words and sacred objects without literally mixing them together.

The striking detail is not necessarily bones lined up beside books, but the shared habit of using written records to preserve both texts and the material signs of faith.
