drawing of foot michelangelo record christies 1234772662

A previously unknown red-chalk drawing by Michelangelo, a study for the foot of the Libyan Sibyl from the Sistine Chapel ceiling, sold for $27.2 million at Christie’s New York on Thursday, far exceeding its $1.5–$2 million estimate. The work was submitted to Christie’s online estimate portal last March by an anonymous owner who inherited it from their grandmother; it had hung on a wall for years, assumed to be a copy. After months of authentication using infrared reflectography and cross-referencing with drawings at the Metropolitan Museum of Art and the Uffizi Gallery, Christie’s specialists confirmed it as an authentic Michelangelo. The sale set a new auction record for the artist, surpassing the previous $24.3 million record set at Christie’s Paris in 2022.

gauguin self portrait kunstmuseum basel authenticity report 1234759147

The Kunstmuseum Basel has confirmed that a Paul Gauguin self-portrait, titled *Portrait de l’artiste par lui-même* (1903), is an authentic work by the French painter, despite decades of scrutiny. The painting, held by the museum since 1945, was subjected to scientific analysis—including pigment testing, radiography, and infrared reflectography—at the Bern Academy of the Arts after amateur art sleuth Fabrice Fourmanoir claimed it was actually painted by Gauguin’s friend Ky-Dong Nguyen Van Cam. The tests showed the pigments date to Gauguin’s era, but also revealed overpainting on the face, possibly done between 1918 and 1926, though the museum found no evidence of intentional forgery.

The Museum of Modern Art (MoMA) has completed an extensive conservation project on Andrew Wyeth's iconic painting "Christina's World" (1948), which will soon return to public view. MoMA senior collections photographer Adam Neese documented the process, using advanced imaging techniques such as high-magnification photography, raking light, and infrared reflectography to reveal hidden layers and reworkings by Wyeth. The analysis showed that Wyeth altered the eaves of the house, shed, and horizon line, deepening the painting's emotional isolation. The conservation team also studied the paint's chemical makeup, noting tiny bubbles from water added to egg yolks in the tempera.

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.

The Kunstmuseum Basel has launched a fresh scientific investigation into a painting long believed to be Paul Gauguin's final self-portrait, *Self-Portrait with Glasses* (1903), after amateur art sleuth Fabrice Fourmanoir raised doubts about its authenticity. Fourmanoir claims the work may have been painted not by Gauguin but by a Vietnamese revolutionary named Ky Dong, a close acquaintance of the artist, after Gauguin's death. The museum, which has owned the painting since 1945, confirmed it is re-examining the work using modern techniques like infrared reflectography and radiology, with results expected by June or July.

Researchers Link Two Unattributed Works To Michelangelo

Researchers have attributed two previously unattributed works to Michelangelo. The Royal Institute for Cultural Heritage of Belgium used radiocarbon dating, pigment analysis, and infrared reflectography to link a 16th-century oil-on-canvas Pietà to the master, finding monograms and a date consistent with his work. Separately, Italian researcher Valentina Salerno published a decade-long study using archival documents and stylistic analysis to attribute a marble bust of Christ in a Roman basilica to Michelangelo.

anne boleyn portrait witch rumors 1234771856

A portrait of Anne Boleyn at Hever Castle in England has been revealed through infrared reflectography to have been altered to show her hands, countering rumors that she was a witch with six fingers. Tree-ring analysis dates the painting to around 1583, during the reign of her daughter Elizabeth I, making it the earliest known likeness of Boleyn. The underdrawing lacked hands, suggesting the unknown artist deliberately added them to rebut claims by Catholic activist Nicholas Sanders that Boleyn had six fingers.

Technical analysis of a 16th-century portrait of Anne Boleyn at Hever Castle has revealed that the artist deliberately reworked the queen's hands to clearly display five fingers. Using infrared reflectography and tree-ring dating, researchers determined the painting dates to 1583, during the reign of her daughter, Elizabeth I. This specific composition, known as the 'Rose' portrait, is now identified as the earliest scientifically dated panel portrait of the doomed queen.
