A team of scientists from Case Western Reserve University has developed a new AI model named PATCH that analyzes tiny sections of paintings to identify the number of artists involved in their creation. The model was applied to two works by El Greco, suggesting that 'The Baptism of Christ,' long thought to be a collaborative workshop piece, may have been painted primarily by the master himself.
Une IA suggère qu’El Greco pourrait être l’unique auteur du Baptême du Christ
A new scientific study published in the journal Science Advances challenges the long-held belief that El Greco's monumental painting 'The Baptism of Christ' was completed by his workshop. Using a deep-learning tool called PATCH to analyze the painting's surface topography, researchers from Case Western Reserve University found a technical consistency suggesting the work was executed by a single hand, likely El Greco himself, despite visible variations in execution.
New research using artificial intelligence has challenged the long-held belief that El Greco's altarpiece *The Baptism of Christ* was largely painted by his son and workshop assistants. A machine-learning model called Patch, developed by researchers at Western Reserve University, analyzed the painting's microscopic surface texture and found underlying connections suggesting El Greco himself painted the majority of the work, with only a small region at the bottom attributed to other hands.
Researchers at the University of California, Berkeley, have discovered a new color called "olo" that cannot be seen under normal conditions. The color, described as a highly saturated blue-green, was perceived by five human subjects during tests using a complex laser system and custom software named Oz. The team published their findings in *Science Advances* on April 18, explaining that olo results from stimulating only the medium-wavelength cone cells in the retina, a feat not possible with natural light. British artist Stuart Semple has since created a physical paint called YOLO, claiming it is the closest approximation to this elusive color, priced at $10,000 per 150ml bottle.
Selon une IA, Greco serait en réalité l’unique auteur du « Baptême du Christ » de Tolède, longtemps considéré comme une œuvre d’atelier
A new study published in Science Advances uses an AI tool called Patch to analyze the monumental painting "Le Baptême du Christ" (1608–1614) by El Greco, long believed to be a workshop piece completed by his son Jorge Manuel Theotocópuli. By mapping the 3D microtopography of the brushstrokes and comparing them with El Greco's authenticated "Christ on the Cross" at the Cleveland Museum of Art, the AI found consistent painterly gestures across the entire work, suggesting the master himself painted it despite tremors from neurological disorders in his old age.
Three Texas-based researchers have successfully radiocarbon dated ancient cave paintings in the Lower Pecos Canyonlands along the Rio Grande border between Mexico and West Texas, using a novel combination of technologies. By dating the deer bone marrow used as a paint binder—rather than the mineral pigments themselves—and employing plasma oxidation to extract carbon, the team analyzed 53 figures across 12 sites. Their findings, published in *Science Advances*, reveal that individual murals were created in single painting events, not accumulated over centuries, and that the paintings span four millennia, from about 5,760 to 1,035 years ago.
