DALLAS, TX.- Heritage Auctions will offer a previously unknown full-scale oil study by John Constable for his celebrated The Cornfield in the National Gallery, London, as the lead lot in its June 5 Important European Art auction, following a major scholarly and conservation investigation that has authenticated the work as an autograph painting by the artist.

The monumental study, which remained hidden in plain sight for decades at the Jefferson Historical Society and Museum in Jefferson, Texas, fundamentally reshapes understanding of the genesis of one of Constable’s greatest paintings, now in the collection of the National Gallery, London.

Widely regarded alongside The Hay Wain as one of the defining achievements of British landscape painting, The Cornfield occupies a notable position within British art history. Exhibited at the Royal Academy in 1826, the painting depicts a shepherd boy drinking from a stream along Fen Lane near East Bergholt in Suffolk, where Constable spent his childhood. Following the artist’s death in 1837, admirers purchased the painting and presented it to the National Gallery, making it the first work by the artist acquired for the national collection.

“This is one of the most important Constable discoveries in decades,” says Marianne Berardi, Heritage’s Co-Director of European Art. “Not only because it is a previously unknown autograph work tied directly to The Cornfield, but because it significantly deepens our understanding of how Constable developed one of the defining images of British art.”

The subject was deeply personal to Constable. He walked Fen Lane daily as a schoolboy traveling between East Bergholt and nearby Dedham, and the landscape remained inseparable from his identity as a painter. “Painting is with me but another word for feeling,” he famously wrote, connecting the banks of the River Stour and memories of his “careless boyhood” to the origins of his artistic vision.

Long admired for its atmosphere of rural stillness and autobiographical resonance, The Cornfield has remained one of Constable’s most celebrated paintings. Yet until now, the details of how the artist arrived at the final composition were not fully understood.

The rediscovered study changes that.

Among the most important revelations is that Constable did not move directly from small preliminary sketches to the final exhibition canvas, as had long been assumed. Instead, the painting confirms that during this mature period of his career he continued the practice of creating full-scale preparatory studies alongside his finished compositions.

According to extensive research undertaken by Anne Lyles — a leading authority on Constable — together with Sarah Cove, accredited paintings conservator and founder of the Constable Research Project, the newly identified work stood beside the finished painting in Constable’s London studio during the winter months of 1826 as the artist developed the final composition.

Technical analysis revealed not only complete consistency with Constable’s materials and working methods, but also evidence that the artist worked on the canvas during two separate periods. The findings suggest that the conception of The Cornfield may have begun years earlier than scholars previously believed.

Infrared reflectography, pigment analysis and cleaning tests uncovered a layered process beneath the painting’s surface. Differences in paint application, combined with evidence that earlier passages had fully dried before later work resumed, indicate that Constable returned to the composition after a significant interval. Lyles and Cove speculate that the project may have originated as early as 1823 for an earlier commission the artist did not complete before evolving into the monumental working study for the 1826 masterpiece.

“The technical evidence transformed our understanding of the picture,” says Berardi. “Infrared examination, pigment analysis and the structure of the paint itself all confirmed that this was not a copy, but a working study created by Constable as he developed The Cornfield. Discoveries of this caliber are extraordinarily rare.”

The painting’s path to Texas is itself remarkable.

The Jefferson Historical Society and Museum acquired the work in 1970 as a gift from Newhouse Galleries in New York during an effort to build the institution’s collection inside its historic Victorian courthouse building. At the time, Newhouse Galleries identified the work as “the large sketch for the painting now in the National Gallery in London,” and Constable scholar Carlos Peacock reportedly endorsed its significance.

Over subsequent decades, however, uncertainty emerged around the attribution. Constable scholarship was still in its infancy during the mid-20th century, and more than 85 known copies of The Cornfield complicated efforts to establish authenticity. Without definitive provenance before its appearance at Newhouse Galleries, the painting was effectively left untraced.

That changed in 2017, when the Jefferson museum contacted Heritage Auctions to evaluate portions of its collection as part of a proposed reinstallation initiative. Questions quickly emerged about the purported Constable. Beneath the aged varnish and layers of surface dirt, something about the composition appeared more significant than previously assumed.

At Berardi’s recommendation, the museum commissioned a comprehensive scholarly and conservation study. The painting was shipped to England, where it underwent extensive technical examination before receiving a sensitive restoration by Cove.

The result was not merely a reattribution, but the recovery of a major work within Constable’s oeuvre.

The reemergence of the painting carries an additional historical resonance: The study appears at auction exactly 200 years after The Cornfield was first exhibited at the Royal Academy in 1826, and during the 250th anniversary year of Constable’s birth.

For scholars, the work offers important new insight into Constable’s mature artistic process. For collectors and institutions, it represents the reemergence of a work long absent from Constable scholarship and an opportunity to acquire the working study for one of the artist’s most beloved Suffolk landscapes.

“The extraordinary thing,” says Berardi, “is that this painting survived quietly for decades, hidden in plain sight. And now
