Christie’s has announced the discovery of a previously unknown Michelangelo drawing. A preparatory study for the Sistine Chapel ceiling. The revelation emerged from an unsolicited photograph submitted through the auction house’s online portal, representing one of the most significant Old Master discoveries in recent memory.
The red chalk study depicts a right foot for the monumental Libyan Sibyl figure. It will be offered at Christie’s New York on 5 February 2026, carrying an estimate of $1.5-2 million. This marks the first unrecorded study for the Sistine ceiling ever to appear at auction.
A Digital Age Discovery with Renaissance Roots
The story began in March 2025 when Giada Damen, a specialist in Christie’s Old Master Drawings Department, received a routine notification on her computer. An anonymous owner from the West Coast had submitted photographs through Christie’s “Request an Auction Estimate” portal.
The photographs revealed a small drawing of a foot, measuring just 5¼ × 4⅝ inches, executed in the distinctive red chalk favoured by Renaissance masters. The work had been inherited from the submitter’s grandmother and had remained within the same European family lineage since the late 1700s, though its attribution had remained a mystery.
“As soon as Damen saw the photograph, she recognized that it had significant quality and seemed to be of the period. Although Damen’s eye told her she was dealing with something special, her head told her not to jump to conclusions,” the auction house revealed in its announcement.
The Authentication Journey
What followed was an intensive six-month investigation. Damen immediately travelled to examine the work in person, and with the owner’s consent, brought the piece to Christie’s New York headquarters for comprehensive analysis.
The authentication process employed cutting-edge technology alongside traditional connoisseurship. Infrared reflectography revealed hidden drawings on the verso of the sheet, concealed beneath the mounting paper, that appeared consistent with 16th-century Italian draughtsmanship in Michelangelo’s circle.
The breakthrough came when Damen recognised striking similarities between the newly discovered drawing and a famous Michelangelo sheet housed at the Metropolitan Museum of Art in New York. Both works shared the same distinctive red chalk medium, comparable artistic technique, and subject matter relating to the Libyan Sibyl.
Furthermore, a copy of the Metropolitan Museum sheet held in Florence’s Uffizi Gallery provided the crucial missing link. This copy showed the same studies as the New York drawing, but with one significant addition: the identical foot depicted in the Christie’s discovery.
The Decisive Moment
The authentication reached its climax when Damen arranged to examine both drawings side by side at the Metropolitan Museum. “I was so excited. It was clear that the two studies had come were by the same hand, done in the same moment,” Damen recalled of this pivotal moment.
The evidence proved conclusive.
The Christie’s drawing had been executed contemporaneously with the Metropolitan Museum sheet, using identical red chalk and created for the same ambitious project. While the Met’s sheet contains studies of the Sibyl’s back, head, left foot, toes, and left hand, the newly discovered work depicts the figure’s right foot, completing the artistic puzzle after more than five centuries.
Both sheets also feature anatomical studies on their reverse sides, executed in black chalk and bearing the unmistakable hand of the Renaissance master. The Christie’s drawing showed clear evidence of having been cut from a larger sheet, consistent with the working methods documented in other Michelangelo preparatory studies.
Historical Provenance and Attribution
The drawing’s authenticity is further supported by a distinctive inscription in brown ink: “Michelangelo Bona Roti,” written in a 16th-century hand. This same inscription appears on several authenticated Michelangelo drawings, including the Metropolitan Museum sheet, providing a clear provenance trail.
Through this inscription, scholars have traced the work’s ownership from artists in Michelangelo’s immediate circle during the 16th century to a 17th-century Italian collection. By the 18th century, the drawing had entered the collection of Armand Louis de Mestral de Saint-Saphorin (1738-1806), a Swiss diplomat in service to the King of Denmark, before passing down through family inheritance to the present owner.
The drawing has never appeared on the art market and remains unpublished in scholarly literature. It has remained in private hands for centuries, unknown to academics and unrecorded in institutional databases.
The Sistine Chapel Connection
The newly discovered study relates to one of Western art’s most celebrated achievements: Michelangelo’s frescoes on the Sistine Chapel ceiling. Created around 1511-12, during the artist’s work on the second phase of the ceiling’s decoration, the drawing captures the powerful dynamism that characterises the Libyan Sibyl figure.
This monumental figure, positioned at the eastern end of the Sistine ceiling, demonstrates Michelangelo’s mastery of human anatomy and movement. The Sibyl is depicted in a dramatic twisted pose, with her feet pressing firmly against the supporting platform, bearing the weight of a figure that measures three times human scale.
The red chalk study exemplifies the careful attention to anatomical detail that made Michelangelo legendary.
Market Significance and Rarity
The discovery carries profound implications for the Old Master market. Of approximately 600 surviving Michelangelo drawings, representing merely a fraction of the thousands he must have created, only around 50 relate to the Sistine Chapel project. More remarkably still, fewer than 10 Michelangelo drawings remain in private hands worldwide, with the vast majority housed in major museums.
“The discovery of a study relating to the Sistine Chapel, a work of art that is arguably the keystone of the Italian Renaissance, has been one of the most memorable moments of my career,” said Andrew Fletcher, Global Head of Christie’s Old Masters Department. “Giada’s discovery, made more than 500 years after the drawing’s creation, represents Christie’s expertise at its finest. It is the kind of story that inspires both the academic and commercial art worlds, while also capturing the imagination of virtually anyone who encounters it, regardless of their background in art.”
Fletcher continued: “In the field of Old Masters, it is difficult to conceive of a more meaningful discovery, and we are thrilled to be offering it for sale in New York on February 5.”
Expert Recognition and Scholarly Consensus
The attribution has received unanimous endorsement from leading international experts in Renaissance art, lending significant weight to the discovery’s authenticity. This scholarly consensus represents years of careful study and peer review within the academic community.
“Making this discovery has been a once-in-a-lifetime opportunity for me,” said Giada Damen, whose decades of expertise culminated in this extraordinary find. “It has been a real pleasure to study this special drawing over the past nine months with my colleagues in the Old Master Drawings Department. We are thrilled to be able to share this finding with the wider world now and proud to bring this exceptional work to the market.”
Damen expressed particular gratitude to the anonymous owner: “I am deeply grateful to the owner for entrusting this work to Christie’s and for his continued collaboration. I also want to acknowledge and express my sincere thanks to the leading international experts we consulted, all of whom have unanimously endorsed the attribution of this drawing to Michelangelo.”
Public Exhibition and Viewing Opportunities
Before the February sale, art enthusiasts will have the opportunity to view this historic discovery in person. The drawing will be displayed at Christie’s London headquarters on King Street from 27 November to 2 December 2025, followed by an exhibition in Christie’s free, public galleries at 20 Rockefeller Center in New York during February 2026, prior to the auction.
These exhibitions represent a rare opportunity for the public to encounter a newly discovered work by one of history’s most celebrated artists.
The intimate scale of the drawing, measuring just over five inches at its longest dimension, will allow visitors to appreciate the subtle nuances of Michelangelo’s technique and the immediacy of his creative process.
The Broader Context of Art Discovery
This remarkable find underscores the continuing potential for significant art historical discoveries in an age when most assume all major works have been identified and catalogued. The digital submission process that initiated this discovery demonstrates how technology can facilitate unexpected encounters between hidden masterpieces and expert knowledge.
The story also highlights the crucial role of specialist expertise in authentication. While digital imaging and scientific analysis provided important supporting evidence, the discovery ultimately depended on the trained eye and deep knowledge of an experienced connoisseur who could recognise exceptional quality and place it within its proper art historical context.
Looking Towards the Auction
As the February 2026 sale approaches, the art market anticipates significant interest from both institutional and private collectors. The combination of impeccable provenance, scholarly endorsement, and the work’s direct connection to one of art history’s most famous projects positions this drawing as a trophy lot of extraordinary calibre.
The estimated price range of $1.5-2 million reflects not only the drawing’s intrinsic artistic merit but also its historical significance and extreme rarity. This significant valuation follows recent trends in the Old Master market, including major Rembrandt works heading to auction.
For collectors, the opportunity to acquire an unknown work by Michelangelo, particularly one related to the Sistine Chapel, represents the kind of once-in-a-generation opportunity that defines the most distinguished collections. Such discoveries are increasingly rare, similar to other recent significant auction findings like Gerrit Dou’s £3M Flute Player or exceptional Fabergé pieces commanding millions.
This discovery serves as a reminder that even in our digitally connected age, art history continues to reveal its secrets. From an unsolicited photograph to a major auction lot, this small red chalk drawing has already travelled an extraordinary journey, one that began over 500 years ago in Michelangelo’s workshop and continues today in the global marketplace for art.
