Rare 13th-Century King Arthur Manuscript Heads to Auction for Millions

Why This Manuscript Is a Medieval Masterpiece

The manuscript, known as the Lebaudy or Clermont-Tonnerre Grail, is the earliest surviving private copy of the Lancelot-Grail cycle, a 13th-century French compilation of Arthurian myths that inspired Thomas Malory’s Le Morte d’Arthur. Dated between 1290 and 1310, it’s the work of the anonymous Master of the Liège Apocalypse, a celebrated illuminator whose signature style—square-jawed knights, burnished gold leaf, and orange cheek dots—makes each miniature a jewel of medieval storytelling.

Dr. Eugenio Donadoni, Christie’s director of medieval and renaissance manuscripts, calls it “a fantastic manuscript.” “It’s beautiful,” he told CBC’s As It Happens, describing the miniatures as “absolutely insane” in their narrative detail. One illustration shows Merlin as a talking stag; another depicts Gawain leaving Camelot to aid a Saxon war. The gold leaf, polished to a high shine, was so expensive in the 13th century that only the wealthiest patrons could afford such opulence.

The manuscript’s provenance is as compelling as its artistry. It passed through the hands of a 15th-century knight, a bibliophile who collected medieval texts obsessively, and Jean Lebaudy, a French industrialist who fought in both world wars and won the croix de guerre twice. “You can see how, throughout history, this manuscript might have appealed to these people,” Donadoni said. The Guardian notes its previous owners included Sir Thomas Phillipps, a Victorian-era collector whose hoard of 80,000 books was once the largest private library in the world.

The Race to Save a Cultural Treasure

The auction isn’t just about art—it’s a cultural battleground. Only three illuminated manuscripts of the Lancelot-Grail cycle are known to exist in private hands, and this is the earliest. Institutions like Cambridge University Library are now scrambling to secure it before it vanishes into another private vault. Dr. Irene Fabry-Tehranchi, a French texts specialist at Cambridge, called the sale “amazing” and “exciting,” The Guardian reported, adding that the manuscript’s public exhibition would finally allow scholars to study it comprehensively.

The stakes are high. The manuscript’s estimated value—£1.5m to £2m (or $2m to $3.7m, depending on exchange rates)—reflects its rarity. But its true worth lies in its historical significance. The Lancelot-Grail cycle is the foundation of Western Arthurian legend, shaping everything from Monty Python and the Holy Grail to Game of Thrones. Patrick Moran, a medieval French literature expert at the University of British Columbia, told CBC that this particular cycle “solidified” Arthur’s place in romantic literature. “Some of the miniatures are absolutely insane,” Donadoni said, emphasizing how the illuminations pack decades of myth into a single page.

Who Will Win the Bid? The Contenders

Three groups are likely to compete: museums, universities, and ultra-wealthy collectors. The British Library, the Morgan Library & Museum, and the Bibliothèque nationale de France have all expressed interest in similar artifacts in the past. But this manuscript’s unique status—the earliest and most illustrated of its kind—could push the price beyond expectations.

Private buyers may also enter the fray. The manuscript’s previous owners were often men of war or wealth—knights, industrialists, bibliophiles—who valued its beauty as much as its history. A bidder with no institutional ties could easily outspend a museum, especially if they see it as a status symbol. Smithsonian Magazine reports that the manuscript’s rebinding in green velvet—a rare survival from its medieval past—adds to its allure, making it as much a collector’s item as a cultural artifact.

What Happens If It Sells Privately?

The biggest risk is that the manuscript disappears into a vault, never to be studied again. Donadoni acknowledged this in his interview with CBC: “With an estimated value of $3.7 million Canadian, there’s no guarantee it won’t disappear again into private vaults.” If that happens, scholars lose a chance to analyze its text, illuminations, and historical context in depth. The manuscript’s current owner, whose identity Christie’s has not disclosed, may have no interest in public access—only in maximizing profit.

There’s precedent for this. The Book of Kells, another masterpiece of medieval illumination, spent centuries in private hands before being donated to Trinity College Dublin in the 19th century. But not all artifacts are so lucky. The Voynich Manuscript, a 15th-century codex of unknown language, remains in a private collection despite decades of scholarly pursuit. If the King Arthur manuscript follows a similar path, future generations may only know it through reproductions.

The Future of Medieval Art in the Auction Age

This sale reflects a broader trend: the commodification of cultural heritage. As private collectors and institutions clash over artifacts, the question arises—should medieval masterpieces be treated as investments, or as public treasures? The answer may hinge on who can afford them.

Christie’s has framed the auction as an opportunity for institutions to acquire a “rediscovered manuscript of one of the greatest of all medieval romances.” But the reality is more complicated. The manuscript’s sale could set a new benchmark for illuminated texts, encouraging more private owners to part with their holdings—or hold tighter. Donadoni’s description of it as “a fantastic manuscript” underscores its artistic value, but the auction’s outcome will depend on whether its cultural significance outweighs its market price.

One thing is certain: whether it ends up in a museum or a private study, this manuscript will shape how we understand King Arthur for centuries to come. As Donadoni put it, “This is a rediscovered manuscript of one of the greatest of all medieval romances … texts fundamental to Western culture.” The question now is who will decide its next chapter.
