A forgotten Rubens masterpiece has been discovered in a Parisian mansion.

The painting "Christ on the Cross", created around 1613 by the Flemish master Peter Paul Rubens, was found during an auction property appraisal and will go under the hammer on November 30, 2025.

A chance find in the sixth arrondissement

Jean-Pierre Ozena, head of the eponymous auction house, discovered the painting in September 2024 while preparing to sell a private mansion in Paris’s sixth arrondissement. The auctioneer was conducting a routine inventory of the property when the Baroque work caught his eye. "This is an extremely rare find that will define my career as an auctioneer," Ozena said in an interview with Agence France-Presse.

The canvas remains in excellent condition, despite its 400-year age. Measuring 105.5 by 72.5 centimeters, it’s relatively compact for Rubens’s large-scale works. "It was painted by Rubens at the height of his talent," the auctioneer emphasized.

Scientific confirmation of authorship

To verify the discovery, Ozena turned to a leading authority on Rubens. German art historian Niels Büttner, who has headed the Centrum Rubenianum in Antwerp since 2021, conducted a thorough study of the painting. This organization is coordinating the publication of the Corpus Rubenianum Ludwig Burchard — a monumental catalogue raisonné encompassing approximately 2,500 compositions and 10,000 works by the Flemish master.

The painting was subjected to X-ray imaging and pigment analysis. These methods allowed the work’s authenticity to be established and confirmed that it was indeed by Rubens. Ozena recalled pacing back and forth while the expert committee reached its decision on authenticity. Then came a phone call from Büttner: "Jean-Pierre, we have a new Rubens!"

The work will be included in the next edition of Rubens’s catalogue raisonné, Addenda and Corrigenda. Prior to this discovery, the painting was known to art historians only from engravings.

Artistic features of the composition

The painting depicts the crucified Christ, a striking figure against a dark, threatening sky. "Christ is depicted as isolated, standing out against the ominous, dark sky," Büttner noted in a document provided to Artnet News. The Savior’s upper body is painfully realistically arched forward, the weight of his body conveyed by the tension of his arms extended above his head.

Beyond the green, overgrown rocky backdrop of Golgotha, illuminated Jerusalem is visible, apparently in a downpour. Such precision of detail was characteristic of Rubens. Ozena described the work as "the very beginning of Baroque painting."

Period of creation and religious context

There are discrepancies regarding the dating of the work: some sources cite 1613, while others indicate the period 1614-1615. This period falls within the first decade after Rubens’s return to Antwerp from Italy in 1609. Between 1610 and 1620, the artist created a large number of altarpieces for Roman Catholic churches.

The Crucifixion was a favorite theme of Rubens, a Protestant who converted to Catholicism. "It is a true confession of faith," Ozena emphasized. The subject of Christ’s crucifixion occupied a central place in Counter-Reformation art, intended to inspire religious fervor in believers.

During the Counter-Reformation, the Catholic Church demanded depictions of the suffering Savior that were more heroic and divine in appearance. Rubens created powerful, emotional images of Christ, the Virgin Mary, and saints, becoming the leading artistic evangelist for Counter-Reformation spirituality in Northern Europe.

Artistic maturity of the master

The painting’s creation coincides with the creation of Rubens’s two great Antwerp triptychs. "The Elevation of the Cross" (1609-1610) combined the Italian influences of Tintoretto and Caravaggio with Flemish realism in a heroic affirmation of redemptive suffering. The second triptych for Antwerp Cathedral, "The Descent from the Cross" (1611-1614), is more classical and restrained, in keeping with its subject matter.

This work reflected Rubens’s energetic renewal of the early Netherlandish tradition of Jan van Eyck, Hans Memling, and Rogier van der Weyden. The widespread fame of "The Descent from the Cross" was ensured by the publication of an engraving — among its future admirers was the young Rembrandt.

Rubens’s finest masterpieces, closely related to the Passion of Christ, were created between 1611 and 1618. Other important religious compositions of this period include The Last Judgment (c. 1616) and Christ on the Cross (also known as Le Coup de Lance, 1620).

Private collection or church commission

Unlike many of Rubens’s works commissioned by the Catholic Church, the discovered painting was likely created for a private collector. This explains its relatively modest size compared to the master’s monumental altarpieces.

The painting is believed to have once belonged to the 19th-century French academic painter William-Adolphe Bouguereau (1825-1905). Büttner noted that it is "astonishing" that a painting of such caliber could have remained unnoticed for so long. He added that if Bouguereau knew of the work’s significance, he did not disclose it.

Bugero as the previous owner

William-Adolphe Bouguereau was one of the most successful French artists of the late 19th century and one of the most celebrated painters of his time. He studied at the École des Beaux-Arts, a prestigious Parisian art school, and was known for his masterful religious, mythological, and allegorical paintings.

Bouguereau’s works were characterized by precise, flawlessly polished paint surfaces and strict adherence to the rules of anatomy, perspective, and academic modeling. His canvases served as models for the standards of French academic painting of the late 19th century and enjoyed considerable popularity in France and the United States.

Bouguereau’s large canvases were sought after by collectors during America’s Gilded Age. However, the term "Bouguereau-esque" was even used as an antonym for Impressionism, as Bouguereau was known as a conservative painter who rejected the paintings of Manet and other Impressionists.

The painting’s journey through the centuries

After leaving the Bouguereau collection, the painting passed to the owners of the Parisian mansion where it was discovered. The document prepared by Büttner contains no information about how exactly the painting came to be found in a 21st-century private residence from a 19th-century collection.

The work’s provenance was certified using methods including X-ray imaging and pigment analysis. These modern technologies allow researchers to peer beneath the paint layers, study the brushwork technique, and determine the composition of the pigments used by the artist.

Rubens and the Art of Calvary

The theme of the crucifixion on Golgotha recurred repeatedly in Rubens’s work throughout his career. The artist was a master of compositional variation — his individual interpretations of Passion scenes were shortened or enriched in keeping with the pious spirit of the time.

The works were adapted to the specific commission, the work’s function and location, and its price. The wide range of different ways of depicting the main characters in Rubens’s "Pietà" and "Descent from the Cross" can be explained by these factors.

In some versions, Mary Magdalene — the embodiment of sinful humanity — adores Christ from afar; in others, she receives the dead Christ in her arms, symbolically receiving the Eucharist after the absolution of sins. These variations reflected the different theological emphases of the Counter-Reformation.

Iconography and Symbolism

In the discovered painting, Rubens used numerous symbolic elements and masterful composition to convey the divine encounter. The rocky backdrop of Golgotha, with its green vegetation, creates a contrast with the gloomy sky, heightening the scene’s drama.

The view of illuminated Jerusalem behind Christ, apparently beneath storm clouds, adds historical and geographical context to the biblical scene. This technique was typical of Rubens, who strove for precision and realism in depicting sacred events.

The isolated figure of Christ, standing out vividly against the dark background, draws the viewer’s gaze and creates a sense of divine presence. The tension in his arms and arched body conveys physical suffering, making the scene excruciatingly realistic.

Baroque style in its early stages

Ozena described the work as "the very beginning of Baroque painting." Rubens is considered the most influential artist of the Flemish Baroque tradition and the embodiment of this style. His work spanned a turbulent century in Europe, filled with political, religious, and cultural events.

The Baroque era, also known as the Age of Rubens, produced many great masters, including Caravaggio, Bernini, and Rubens himself, who personified and defined the style. The Baroque style emphasized movement, color, and sensuality.

By completing the fusion of the realistic tradition of Flemish painting with the imaginative freedom and classical themes of Italian Renaissance art, Rubens fundamentally revitalized and redirected northern European painting.

Italian influence on creativity

In August 1601, Rubens arrived in Rome. There, the new Baroque style proclaimed by Annibale Carracci and Caravaggio — bold naturalism combined with a revival of the heroically idealized forms of Michelangelo and Raphael — was quickly adopted by Rubens.

His first major Roman commission was three large paintings (1601-1602) for the chapel of the crypt of St. Helena in the Basilica of Santa Croce. In 1603, Gonzaga sent him on his first diplomatic mission to Spain to present a consignment of paintings to King Philip III.

Towards the end of 1605, Rubens made a second trip to Rome. Together with his brother Philip, he undertook an intensive study of ancient art and philology and began to assemble a significant collection of Roman sculptures, reliefs, portrait busts, and ancient coins.

Return to Flanders and flourishing

In 1609, Rubens returned to Antwerp after receiving news of his mother’s illness. The Twelve Years’ Truce in the war between Spain and the Netherlands prompted a massive renovation of Flemish churches. This created a huge demand for religious art and opened up unprecedented opportunities for talented artists.

The first of Rubens’s two great Antwerp triptychs, "The Elevation of the Cross" (1609-1610), combined Italian reflections with Flemish realism in a heroic affirmation of redemptive suffering. His second triptych for Antwerp Cathedral, "The Descent from the Cross" (1611-1614), is more classical and restrained in keeping with its subject matter.

It was during this fruitful period, between 1613 and 1615, that the discovered painting "Christ on the Cross" was created. The work demonstrates Rubens’ complete mastery of Baroque technique and his ability to create deeply emotional religious images.

The productivity of the Flemish master

Peter Paul Rubens was an extremely prolific artist. His oeuvre comprises approximately 2,500 compositions and approximately 10,000 works of art: paintings, drawings, book illustrations, and even tapestries. "No undertaking, however vast, has ever surpassed my courage," declared Rubens, whose work included cathedral domes and altarpieces, portraits, landscapes, and sculpture and architectural designs.

Despite such productivity, the discovery of a new masterpiece by a 17th-century artist remains a rare event. "It’s not every day that experts discover another masterpiece by a 17th-century Flemish master," noted Artnet News.

The Role of Centrum Rubenianum

The Centrum Rubenianum is often involved in determining the authenticity of paintings attributed to Rubens. The organization was originally called the "National Center for the Plastic Arts of the 16th and 17th Centuries." Today, its activities focus on the publication of Ludwig Burchard’s Corpus Rubenianum.

Through the research conducted for this catalogue raisonné, Centrum helps expand the Rubenianum’s own documentation, particularly regarding Rubens and his close associates and followers. Centrum also assists the Rubenianum in responding to inquiries about works of art, as well as organizing and participating in exhibitions and publications in Belgium and internationally.

A series of more than 40 catalogue raisonné books presents a comprehensive overview of Rubens’s oeuvre. This monumental project, one of the most ambitious in art history, reflects both the scale and complexity of Rubens’s work. Each volume is written by a distinguished specialist in the research tradition of Ludwig Burchard, a widely recognized authority in the field.

Debates on the authenticity of Rubens’ works

Centrum Rubenianum takes a clear position on the authenticity of Rubens’ works, which sometimes sparks controversy. The painting "Samson and Delilah" in London’s National Gallery has long been questioned by some researchers, including the artist Euphrosyne Doxiadis, who recently wrote a book about it.

However, Büttner firmly rejected the speculation, consistently supporting the attribution to Rubens. "These are conspiracy theories," he said, describing doubts about the origins of "Samson and Delilah." A National Gallery spokesman stated that the painting "has long been recognized by Rubens scholars."

Leading experts in the field unconditionally support the authenticity of the disputed works. Chief among them is Niels Büttner, chairman of the Centrum Rubenianum in Antwerp, who is working on the Corpus Rubenianum, the definitive catalogue raisonné of the Flemish Baroque painter.

Technologies in the attribution of works

Modern technologies are playing an increasingly important role in authenticating works by Old Masters. X-ray computed tomography can be used for non-invasive dendrochronology, revealing details of panels and boards hidden beneath layers of paint.

Pigment analysis allows us to determine the composition of paints and compare them with the materials used by the artist during a given period. However, experts emphasize that artificial intelligence and other technological tools will never replace the expert human eye, but they can be a valuable additional analytical tool.

In the case of the discovered painting "Christ on the Cross," a combination of X-ray imaging, pigment analysis, and Büttner’s expert assessment led to the definitive confirmation of Rubens’ authorship.

The market for Rubens’ religious works

Over the past year, Rubens’ religious paintings have generally met or exceeded expectations at auction, selling for between $1 million and $5 million, according to the Artnet price database. Auction house Osenat has not released a preliminary estimate for the discovered painting.

The lack of an official estimate is not unusual for works of such significance. Auction houses sometimes prefer not to publish an estimate so as not to limit potential buyers and allow the market to determine the price itself.

The auction is scheduled at Osenat auction house in Fontainebleau, France, on November 30, 2025. Further details regarding the Rubens painting, including its estimated sale price, have not yet been disclosed online.

The significance of the discovery for art history

The discovery is of significant interest to art history for several reasons. First, it demonstrates that even in the 21st century, works by renowned masters considered lost for centuries can be discovered.

Secondly, the painting fills a gap in the documentation of Rubens’s oeuvre — the work was known only from engravings, while the original was considered lost. Its inclusion in the next edition of the catalogue raisonné, Addenda and Corrigenda, will expand scholarly understanding of the artist’s oeuvre.

Thirdly, the discovery highlights the importance of careful inventorying of private collections and the diligence of auction professionals. Without Ozen’s experienced eye, the painting could have remained unidentified for decades.

Prospects for future discoveries

The discovery raises the question of how many other works by renowned artists might be in private collections without being properly attributed. Büttner called it "astonishing" that a painting of such caliber could have remained unnoticed for so long.

The fact that the previous owner, William-Adolphe Bouguereau, himself a distinguished artist and art connoisseur, may not have realized the significance of the work in his collection is surprising. This demonstrates that even the collections of renowned collectors of the past can harbor unidentified masterpieces.

Modern research methods and a growing database of Old Masters’ works increase the chances of correctly attributing works of art. Centrum Rubenianum continues to expand its documentation, facilitating the identification of works by Rubens and his circle.

The emotional impact of discovery

For Jean-Pierre Ozena, the discovery was the highlight of his professional career. "This is a masterpiece that was missing, and I’ve found it. This is an extremely rare and incredible discovery, and it will be a landmark moment in my career as an auctioneer," Ozena declared.

The moment of receiving confirmation from Büttner was unforgettable for the auctioneer. After the tense wait for the expert committee’s decision, the phone call with the news, "We have a new Rubens!" brought relief and triumph.

The discovery is also significant for the scientific community. The opportunity to study the original work, previously known only from engravings, opens new perspectives for research into Rubens’ technique and style from 1613 to 1615.

Cultural Heritage and Preservation

The excellent state of preservation of this 400-year-old painting testifies to its proper storage conditions over centuries. This underscores the importance of proper care for works of art to ensure their preservation for future generations.

The upcoming auction will determine the next custodian of this masterpiece. Whether the painting will remain in a private collection or be acquired by a museum is a question whose answer will be known on November 30, 2025.

Regardless of the auction’s outcome, the scholarly community has gained access to an important Rubens work. The painting’s inclusion in the catalogue raisonné will ensure its documentation and accessibility to researchers.
