Up to 60% of medieval texts and 95% of manuscripts have vanished, study finds

A new study using computational simulations estimates that up to 60% of medieval texts—including knight tales and other narratives—and 95% of surviving manuscripts may have been lost over time. Researchers analyzed textual lineage and preservation patterns to reconstruct what was likely destroyed, damaged, or never recorded. The findings suggest a far greater erosion of medieval literary and historical records than previously assumed, with implications for cultural heritage and historical accuracy.

Coverage highlights the study’s reliance on digital modeling to trace manuscript lineages, comparing it to a ‘family tree’ of texts. Outlets including *The Debrief*, *Phys.org*, and *Popular Science* emphasize the alarming scale of loss, particularly for genres like chivalric literature, where only fragments remain. Archaeology-focused publications underscore the broader threat to understanding medieval society through written sources.

Watch for follow-up debates on how to prioritize digitization and preservation efforts, as well as potential archaeological discoveries that might fill some gaps. The study also raises questions about whether similar losses affect other historical periods or regions, though coverage does not yet specify broader applications.
