headline: AI analysis casts doubt on Van Eyck paintings in Italian and US museums
dek: An analysis of two paintings in museums in the US and Italy by the 15th-century Flemish artist Jan van Eyck has raised a profound question: what if neither were by Van Eyck? Saint Francis of Assisi Receiving the Stigmata, the name given to near-identical unsigned paintings hanging in the Philadelphia Museum of Art and the Royal Museums of Turin, represent two of the small number of surviving works by one of western art’s greatest masters, revered for his naturalistic portraits and religious subjects. The only pr…

gain_evidence: said it was 89% likely to be authentic | Art Recognition's previous analyses as "remarkably accurate"

problem_evidence: has been unable to detect any of Van Eyck's brushstrokes | was "91% negative" and that the Turin version was "86% negative" | I'm guessing that the Philadelphia and Turin museums won't be happy. It's not good news on these paintings.
quick_read: On 7 February 2026, The Guardian reported an AI analysis by Swiss company Art Recognition of two near-identical paintings titled Saint Francis of Assisi Receiving the Stigmata held in Philadelphia and Turin and attributed to Jan van Eyck. The system found no Van Eyck brushstrokes, rating the works 91% negative and 86% negative, while rating The Arnolfini Portrait in London 89% likely authentic.

The finding matters because attribution underpins museum display, scholarship, and public trust in Old Master collections, and a negative AI result directly challenges long-held attributions. Uncertainty remains because condition and restoration history may affect brushstroke analysis, and scholars frame the works as possible studio paintings rather than outright forgeries, leaving open whether a lost autograph original exists.
limitation: Critics note painting condition and later restorations may affect AI-based brushstroke analysis, leaving uncertainty about whether negative results reflect authorship or altered surfaces.
tag: Dual reading
key_points: Art Recognition, a Swiss company that collaborates on research with Tilburg University, conducted AI brushstroke analysis on two near-identical unsigned paintings titled Saint Francis of Assisi Receiving the Stigmata. | The Philadelphia Museum of Art version was rated 91% negative and the Royal Museums of Turin version 86% negative for Van Eyck's brushstrokes. | The Arnolfini Portrait in the National Gallery in London was rated 89% likely to be authentic in contrast. | Scholar Till-Holger Borchert said findings support view that both Saint Francis versions were studio paintings produced in the artist's workshop.
rundown: Art Recognition analyzed the Philadelphia and Turin versions of Saint Francis of Assisi Receiving the Stigmata, described as near-identical unsigned paintings among the small number of surviving works by Jan van Eyck. The company reported 91% negative for Philadelphia and 86% negative for Turin, and said it was unable to detect any of Van Eyck's brushstrokes.

CEO Dr Carina Popovici said she expected one painting to be positive and the other negative, but both came out negative, calling the high negative percentages particularly dramatic. Art historian Dr Noah Charney said deeper tests were conducted to confirm the surprising results and suggested both pictures are studio works, implying a lost original more fully by Van Eyck's hand may exist.
