Researchers Identify Enslaved Boy in Joshua Reynolds Painting

Researchers in the U.K. have identified the enslaved boy depicted in Joshua Reynolds's 1748 painting of Royal Navy lieutenant Paul Henry Ourry. For centuries known only as "Jersey," the boy has been identified as George Walker, also called Boston Jersey, through baptismal and admiralty records. Walker was baptized at age 15 in Westminster in 1752, served on HMS Monmouth and HMS Deptford, and was discharged in 1753, after which his fate remains unknown. The research, a collaboration between the National Trust, the National Gallery in London, and Royal Museums Greenwich, also used scientific analysis to reveal Reynolds's original compositional intentions.

There Has Never Been an Apolitical Venice Biennale

"Es hat niemals eine unpolitische Venedig-Biennale gegeben"

The Venice Biennale is embroiled in political controversy, with the US Pavilion's selection process criticized for bypassing traditional curatorial expertise in favor of a politically connected outsider. Simultaneously, a collective of artists and academics is protesting Russia's return to the Biennale, arguing it uses art as a political instrument to normalize its actions amid the war in Ukraine. An analysis in ArtReview contends the Biennale has never been apolitical, serving as a stage for geopolitical power plays since its inception.

Allison Katz’s Playful Paintings Hide Serious Ideas in Plain Sight

Trevor Paglen’s New Book Says AI Is Rewriting What Images Do

Artist Trevor Paglen has published a new book, *How to See Like a Machine: Images After AI*, which argues that generative AI and computer vision are fundamentally changing how images function in culture. Drawing on his decade-long practice, Paglen contends that images are no longer merely representations for human interpretation but have become operational tools—'activations' that trigger automated responses and shape reality. He cites examples such as surveillance cameras at grocery stores, the Samsara navigation system in trucks, and the ImageNet database to illustrate how machine vision systems normalize surveillance in service of capital, a phenomenon he terms 'machine realism.'

Harnessing the winds of societal change: how art dealers have been able to shape taste for centuries

Valentina Castellani, a former Gagosian director, has authored a new book titled *Trading Beauty: Art Market Histories from the Altar to the Gallery* (out 1 May). The book traces how art dealers have historically leveraged societal changes—political, economic, and social—to reshape taste and market structures. Castellani begins in the Middle Ages, when art was made only on commission for patrons like the Catholic church and monarchies, and moves through key shifts such as the Dutch Republic's first open art market in the 17th century, which gave rise to the professional art dealer. She highlights dealers like Paul Durand-Ruel, Joseph Duveen, and Leo Castelli who capitalized on anti-establishment energy, new wealth, and post-war consumer culture to bring avant-garde art to the forefront.

Beaux Arts Magazine presents a detailed dossier analyzing ten iconic masterpieces of Impressionism, including works by Edgar Degas, Édouard Manet, Berthe Morisot, Auguste Renoir, Gustave Caillebotte, Claude Monet, and Mary Cassatt. The article explores the technical innovations, modern subjects, and revolutionary spirit of the movement, which began in 1874 and was initially rejected by critics. Each featured painting—such as *Le Déjeuner sur l’herbe*, *Impression, soleil levant*, and *Le Bal du moulin de la Galette*—is examined by art historians and journalists to reveal its composition, historical context, and lasting impact.

AI Suggests El Greco Could Be the Sole Author of 'The Baptism of Christ'

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.

« L’Angélus » de Millet : une notification à l’humanité hors sol ?

Beaux Arts Magazine publishes a detailed visual analysis of Jean-François Millet's painting "L'Angélus" (1857–1859), housed at the Musée d'Orsay in Paris. The article describes the scene of two peasants pausing their potato harvest to pray at dusk, examining the composition, color, and spiritual resonance of the work. It also traces Millet's biography—from his peasant origins in the Cotentin region to his training under Langlois and Paul Delaroche, and his early career painting portraits and nudes before turning to rural subjects.

A Titanic Face-to-Face Brings Together the Vibrant Bodies of Rodin and Michelangelo at the Louvre

Un face-à-face titanesque réunit les corps vibrants de Rodin et Michel-Ange au Louvre

The Louvre has mounted an exhibition that places the works of Auguste Rodin in direct dialogue with those of Michelangelo, focusing on the profound influence of the Renaissance master on the 19th-century sculptor. Key sculptures like Rodin's 'Adam' and 'The Age of Bronze' are juxtaposed with Michelangelo's 'Dying Slave' and 'Rebellious Slave', highlighting shared themes of contorted male forms and masterful use of contrapposto.

A.I. Identifies Holbein Drawing as Possible Portrait of Anne Boleyn

Researchers at the University of Bradford have used artificial intelligence to analyze preparatory drawings by Hans Holbein the Younger in the Royal Collection at Windsor Castle. The AI model, which previously identified a forgotten Raphael painting, suggests that a drawing long believed to depict Anne Boleyn actually shows her mother, Elizabeth Howard, while another drawing labeled "Unidentified Woman" likely portrays Anne Boleyn herself. The findings, published in Heritage Science, are based on biometric analysis of facial features, bone architecture, and proportional relationships, offering quantifiable evidence to resolve long-standing scholarly uncertainty about the sitters' identities.

Mystery sitter in Holbein portrait could be Anne Boleyn, AI analysis finds

Researchers using AI have analyzed two Renaissance sketches by Hans Holbein from the Royal Collection, known as the Windsor sketch and the Unidentified Woman. The AI model, developed by Professor Hassan Ugail at the University of Bradford, compared the entire Holbein corpus and found that the Unidentified Woman may actually be Anne Boleyn, while the Windsor sketch—long thought to depict Boleyn—may instead show her mother, Elizabeth Howard. The study suggests the works were incorrectly inscribed in the 1700s, leading to centuries of misidentification.

CK Reed Illustrates Chicago's Neighbors Boutique Art Fair

Artist and illustrator CK Reed provides a visual and narrative account of the inaugural Neighbors Boutique Art Fair in Chicago. Founded by Mirka Serrato and curated by Jonny Tana, the fair transformed a historic residence on Astor Street in the Gold Coast into an intimate, domestic exhibition space. The event focused on a "non-conforming cultural proposal," deliberately platforming underrepresented communities and galleries within a setting that prioritized human connection over the typical commercial whirlwind of larger fairs.

Performance, gioco, rischio. Il grande Paul McCarthy è in mostra a Madrid: l’intervista

Paul McCarthy's latest exhibition, titled "A&E," is on view at Bowman Hal gallery in Madrid, part of the SOLO CONTEMPORARY initiative founded by a Spanish collector couple. The show features large-scale works on paper and videos created in collaboration with German actress Lilith Stangenberg, exploring role-play, performance, and the blurred lines between art and entertainment. The acronym "A&E" alludes to historical pairs like Adam and Eve or Adolf Hitler and Eva Braun, as well as "Arts & Entertainment." The works stem from private encounters between McCarthy and Stangenberg, with drawings serving as storyboards for videos that capture their improvisational, trance-like interactions.

The New Exhibitions of the Pinacoteca Agnelli and the New Public Works on the Lingotto Park-Track: The Photos

Le nuove mostre della Pinacoteca Agnelli e le nuove opere pubbliche sulla pista-parco del Lingotto: le foto

The Pinacoteca Agnelli in Turin has launched a new exhibition program that includes the first major institutional retrospective in Italy dedicated to Swiss photographer Walter Pfeiffer, titled "In Good Company," running until September 13, 2026. Curated by Nicola Trezzi and Simon Castets, the show features over 100 photographs from the 1970s to today, blending iconic and unseen works that explore queer eroticism, everyday artifice, and collaborative image-making. Concurrently, the museum presents "Modigliani sottopelle. Quattro capolavori" as part of its "Beyond the Collection" series, placing four masterpieces by Amedeo Modigliani—including a loan from the Staatsgalerie Stuttgart and works from the Centre Pompidou—in dialogue with the permanent collection. Curated by Pietro Rigolo and Beatrice Zanelli, the exhibition takes an interdisciplinary approach combining art history, diagnostics, and scientific research, using an algorithm to analyze canvas weaves and propose a new dating for the iconic "Nu couché" acquired by Giovanni and Marella Agnelli in 1960.

The Poetics of Error Between Art and Architecture

La poetica dell’errore tra arte e architettura

This essay challenges the historical obsession with perfection in architecture and art, rooted in Hegelian philosophy where beauty is equated with truth and flawlessness. It argues that the pursuit of the 'ideal' is a cognitive bias that ignores the value of complexity and structural failure. By reframing the 'error' not as a mistake but as a generative method, the text suggests that imperfection is often what elevates a work to the status of a masterpiece.

Mystery 17th-Century Portrait Sparks Search for Identity of Black Sitter

Researchers at the National Portrait Gallery in London have launched a landmark investigation into a rare 17th-century double portrait featuring a Black boy and a white boy standing side-by-side. The painting, which has hung at the historic Penshurst Place in Kent for centuries, is undergoing extensive restoration and technical analysis to identify the sitters. Experts are particularly struck by the composition, which depicts the Black figure at the same scale and status as the white figure, a significant departure from the era's typical portrayal of Black individuals as marginal attendants.

How Art Firms Are—or Should Be—Using A.I. Right Now

Art firms are increasingly experimenting with artificial intelligence, but concrete use cases remain limited and industry-specific tools are still in their infancy. A new partnership between Bonhams and tech company ARTDAI aims to apply AI to market analytics, valuation, and specialist research, while companies like Artsy and Artnet are integrating AI capabilities into their platforms. Industry experts, including former Art Basel chief Marc Spiegler, note that the art market's small size has historically discouraged tech development, but AI now makes high-performance tools accessible to smaller businesses.

Has A.I. Solved the Mystery of This El Greco Painting?

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.

In This Nazi-Era Restitution Dispute, the Focus Turns to a Missing Cow

A family is seeking restitution of a painting they believe is a lost Rubens work, looted by Nazis during World War II. However, an expert has cast doubt on the claim, arguing the painting is a copy because it lacks a distinctive detail found in the original: a urinating cow. The dispute has shifted focus to this missing element, complicating the family's efforts to recover the artwork.

Blank Spaces. Sung Tieu by Sarah Johanna Theurer

Sung Tieu's installations, characterized by austere, bureaucratic surfaces, explore the hidden architectures of power embedded in everyday systems. The article examines her series of works that deconstruct administrative forms used in asylum procedures, reducing them to blank spaces and quantified grids to expose how institutional power operates through seemingly neutral documents. Her exhibition "In Cold Print" at Nottingham Contemporary physically manifests these themes by using steel fences to control viewer movement, drawing direct parallels between minimalist sculpture and the dehumanizing design of border controls.

Robert Filliou, artistes océaniens… Que nous réserve la prochaine édition de la Biennale de Lyon ?

The 18th edition of the Lyon Biennale, titled "Passer d’un rêve à l’autre" (Moving from One Dream to Another), will run from September 19 to December 13, 2026.
