Lost John Constable Painting Rediscovered in Texas Bound for Auction

A long-lost, large-scale oil study by John Constable for his famous painting *The Cornfield* has been rediscovered and authenticated after decades in a rural Texas museum. Scientific analysis, including pigment tests and infrared reflectography, confirmed the materials and techniques match Constable's own, leading experts to declare it the largest known study for the 1826 masterpiece. The work, which had been mistakenly cataloged as a copy, will now be auctioned by Heritage Auctions in Dallas this June.

Marc Restellini’s ‘atom bomb’ of a Modigliani catalogue raisonné is finally published

After nearly three decades of legal disputes and intense research, Marc Restellini has finally published his definitive catalogue raisonné of Amedeo Modigliani’s oil paintings. Released through the Institut Restellini and Yale University Press, the six-volume work utilizes forensic scientific analysis, spectrometry, and archival evidence to authenticate the artist's oeuvre. The publication includes 100 newly authenticated works while excluding 15 previously accepted paintings due to a lack of definitive evidence, marking a shift from connoisseurship to a fact-based methodology.

ronald perelmans 410m trial finally begins

Billionaire collector Ronald Perelman's $410 million insurance trial has finally begun after seven years of litigation, over 1,500 court filings, and a 2018 fire at his East Hampton estate. The dispute centers on five paintings by Cy Twombly, Ed Ruscha, and Andy Warhol that survived the fire but were exposed to smoke and sprinklers. Perelman claims the works lost their market appeal—their "oomph"—while insurers at Lloyd's of London dispute any detectable damage and allege Perelman quietly tried to sell some of the pieces. The trial has also revealed that Perelman sold over 70 works from his collection after a margin call from Deutsche Bank, with some contested paintings used as collateral.

artdiscovery launches insured authenticity guarantee

ArtDiscovery, a scientific art analysis firm with offices in London and New York, has launched what it calls the world's first insured authenticity guarantee for artworks. The service combines connoisseurship, provenance research, laboratory science, and proprietary AI, then backs the conclusion with an insurance policy from an A+ rated global insurer. If a certified attribution is later proven incorrect, the policy covers financial loss to the artwork's owner. The company's CEO, Denis Moiseev, and CFO, Steven Maslow, explained that the insured certificate is priced at 60 basis points of the certified value and travels with the artwork as a transferable warranty. The launch follows ArtDiscovery's acquisition by Hephaestus Analytical, a London-based tech company that uses AI, provenance research, and chemical analysis for authentication.
