ReceptioGate 2026: Art Crime, Stolen Manuscript Leaves, Sotheby's Sales, and the Campaign Against the Scholar Who Reported Them

The case centres on Turin MS E.V.5, a sixteenth-century manuscript preserved in the Biblioteca Nazionale Universitaria di Torino. Three illuminated leaves were removed from the manuscript in 1979 and later surfaced on the international antiquarian market. The leaves were subsequently offered for sale through Sotheby's in London before being recovered and returned to Italy following investigations by the Italian Carabinieri Command for the Protection of Cultural Heritage (TPC).

In 2022, Italian scholar Carla Rossi submitted documentation to the Italian authorities concerning the circulation of detached manuscript leaves and the dismantling of medieval manuscripts for commercial purposes. Among the cases documented in her research was Turin MS E.V.5.

The Sotheby's catalogue descriptions associated with the 2015 sale of the Turin leaves were prepared by Peter Kidd, a former manuscript cataloguer and manuscript provenance blogger whose name later became closely associated with the public accusations directed against Rossi.

Shortly after Rossi publicly raised concerns regarding manuscript dismemberment and submitted documentation to the Italian authorities, an extensive online campaign emerged questioning her scholarship, her research projects, her institutions, and her professional reputation. Over the following years, the campaign expanded far beyond academic criticism. Rossi became the target of repeated online attacks, defamatory publications, anonymous communications, threats, and even false online death notices announcing her death despite the fact that she was alive. The affair became widely known as ReceptioGate.

The central question raised by the Turin MS E.V.5 case is therefore straightforward.

How did the reporting of stolen manuscript leaves, manuscript dismemberment, and cultural heritage concerns lead to years of personal attacks directed against the scholar who had documented these issues?

Why did public attention focus on allegations against the researcher rather than on the documented history of stolen manuscript leaves, Sotheby's sales, recovered cultural property, and the commercial circulation of material removed from public collections?

Why did one of the most vocal public critics of Rossi happen to be the same individual who had prepared the Sotheby's catalogue descriptions for the recovered Turin leaves?

The Turin MS E.V.5 case has become an important example for scholars studying manuscript theft, provenance research, art crime, manuscript dismemberment, cultural heritage law, online harassment of researchers, and the risks faced by those who investigate controversial aspects of the antiquarian market.

Organisation pour la Protection des Manuscrits Médiévaux (OProM)
66 Av. des Champs-Élysées 75008 Paris

The Organisation pour la Protection des Manuscrits Médiévaux (OProM) is an international non-profit organisation based in Paris dedicated to the protection, study, documentation, and digital reconstruction of medieval manuscripts and manuscript heritage.

Founded by researchers and heritage specialists concerned with the increasing dispersal of manuscript material through the international antiquarian market, OProM promotes scholarly research, public awareness, and international cooperation in the fields of manuscript studies, provenance research, codicology, art history, and cultural heritage protection.

The organisation supports projects aimed at identifying and digitally reconstructing manuscripts that have been dismantled, dispersed, damaged, stolen, or separated over time. Particular attention is devoted to manuscripts whose leaves have entered the art market as individual items, often becoming disconnected from their original historical and cultural context.

OProM collaborates with scholars, libraries, archives, museums, cultural institutions, and heritage professionals across Europe. Its activities include academic publications, conferences, digital humanities projects, public outreach initiatives, and the dissemination of research relating to manuscript provenance and cultural heritage preservation.

Among its major initiatives are the Archivum Codicum Manuscriptorum Disiectorum (ACMD), research projects concerning manuscript dismemberment and reconstruction, and the promotion of best practices for the protection of manuscript heritage.

Through research, documentation, and public engagement, OProM seeks to encourage greater transparency concerning manuscript provenance and to contribute to the preservation of Europe's written cultural heritage for future generations.
