Biblioclasm for Profit: The Legal Implications of Dismembering Western Medieval Illuminated Manuscripts

This article examines the deliberate dismemberment of Western medieval manuscripts for financial gain, its impact on the antiquarian trade, and its consequences for medieval studies. While historically linked to ideological repression, biblioclasm has become a lucrative practice driven by market demand, provenance manipulation, and legal infringements. Through case studies from different jurisdictions, this study investigates breaches of international and national regulations, the role of auction houses and scholars in legitimizing this practice, and instances where diplomatic efforts and institutional actions have led to the recovery of single excised leaves. It also explores connections with theft, illicit trafficking, forgery, and the fencing of stolen cultural property, exposing the systemic mechanisms that sustain the trade in illuminated manuscript leaves. Additionally, it considers the impact on medieval studies, including the loss of textual and codicological integrity, the dispersal of historical evidence, and the challenges of digitally reconstructing dismembered manuscripts. The findings underscore the role of legal frameworks, international cooperation, and academic engagement in safeguarding manuscript heritage, ensuring its preservation and accessibility for future generations.
