CNR: Stolen Messina artworks have scientific fingerprint useful for recognition

Artworks stolen from the Messina Regional Museum by Antonello da Messina possess a unique scientific 'fingerprint' that could aid in their identification if they are recovered, according to Italy's National Research Council (CNR).

In 2018, both stolen works underwent a complete diagnostic documentation campaign. Researchers from the CNR's Institute for Chemical-Physical Processes (Cnr-Ipcf) in Messina and the University of Palermo's Stebicef Department employed a coordinated set of non-invasive and non-destructive methodologies. These techniques, including digital radiography, infrared imaging, UV and X-ray fluorescence, Raman spectroscopy, and diagnostic imaging, aimed to thoroughly analyze the material characteristics and conservation status of the paintings.

The combined data from these techniques can generate a diagnostic signature for the artworks. This scientific documentation is considered particularly valuable for verification purposes should the paintings be found. The CNR highlighted that this 'impronta diagnostica' (diagnostic imprint) is specific to each piece.

Meanwhile, the four custodians who were on duty at the Accascina Museum in Messina on the evening of August 15, when the theft occurred, have been transferred to other cultural heritage sites. These individuals, two regional employees and two ASU (Azienda Siciliana Trasporti) workers, are currently on leave but will not return to their posts at the museum. Disciplinary proceedings, potentially leading to dismissal, will be initiated against them once the regional Department of Cultural Heritage receives a report from the museum director, Marisa Mercurio.
