A remarkable medieval manuscript is set to auction this summer, featuring tales of King Arthur and Merlin. This 700-year-old treasure, known as the Clermont-Tonnerre Grail, has been in private hands for centuries and offers a rare glimpse into medieval literature.
Dating back to the 13th or 14th century, this manuscript is considered one of the earliest documents that narrate the legendary quest for the Holy Grail. Experts predict it could sell for as much as $2.7 million at Christie’s auction house in July.
Written between 1290 and 1310, the manuscript contains Old French text from the Lancelot-Grail cycle. It is filled with 126 beautiful gold-leaf illustrations, showcasing scenes of Arthur and his knights, as well as transformational depictions of Merlin himself. Eugenio Donadoni, a director at Christie’s, highlights the significance of these illustrations in capturing the enduring appeal of these legendary stories.
Interestingly, this manuscript has never been publicly displayed or deeply examined, adding to its allure. Donadoni mentions that manuscripts like this are virtually unknown. He notes, “This is a rediscovered manuscript of one of the greatest of all medieval romances.”
What makes this auction even more fascinating is its provenance. The manuscript has a long list of past owners, from a 15th-century knight to a modern industrialist active during both World Wars. This rich history may attract not just private collectors, but also institutions eager to showcase its cultural significance.
In a recent online poll, many expressed excitement about the auction, with a significant number wanting to learn more about medieval literature. Such interest reflects a broader revival in the appreciation of historical texts, likely influenced by the rise of social media discussions around culture and heritage.
Donadoni describes this manuscript as enticing from many angles: historical, artistic, and cultural. He emphasizes that the story is timeless, echoing Merlin’s own words: “And the story will forever be told and gladly heard for as long as the world lasts.”
The auction is set for July 8 at Christie’s in London. Those interested won’t want to miss this opportunity to bid on a piece of history that weaves together mythology, artistry, and cultural heritage. For more information about the auction, visit Christie’s auction page.
