King Arthur, according to ancient texts, was a 6th century British leader who became legendary in the dramatic era after the Roman Empire lost its grip on Britain. The recovered text belongs to the Suite Vulgate du Merlin – a continuation of the folktales of King Arthur written down in the 13th century as part of the so-called Vulgate Circle – a medieval French prose cycle that includes the stories of the knight Lancelot, the Holy Grail and the wizard Merlin.
The Vulgate Circle consists of several linked knightly romances and stories about the Holy Grail, written in Old French. The authorship of these works is unknown, but there are strong indications that they were the result of collaboration between several scribes. The Suite Vulgate du Merlin is the second part of the cycle and describes the expansion of Arthur’s kingdom, the establishment of the first Knights of the Round Table and the emergence of the bard and seer Merlin as the king’s prophetic advisor. It acts as a bridge to the Lancelot part of the cycle, weaving Merlin into the story of the Holy Grail.
In their day, these stories were medieval bestsellers, distributed via hand-copied manuscripts. Today, fewer than 40 manuscripts of the Suite Vulgate du Merlin survive, and each one is unique because they were written by hand by different people.
The present fragment has been identified as having been written around 1275-1315 and is written in Old French, the language used by the aristocracy and court in England after the Norman Conquest. Small variations in the text – such as a mistake in the name of one of the characters – can help scholars trace its relationship to other versions.
The prose of the Arthurian legends was often aimed at a noble audience, and the decorative design of the manuscript suggests that this text was also intended for such a setting.

Medieval parchment reused as book covers
The fragment in question was discovered in 2019 during a re-cataloging of a 16th century register in Cambridge University Library. Among these documents was a court and land register from Huntingfield Manor in Suffolk. However, when researchers leafed through the worn volume, they discovered that the inside cover contained pages from a much older manuscript. The parchment had been reused and folded, cut and sewn into the binding.
At first, it was difficult to determine what the text was about. Researchers initially thought it was a 14th-century story about the knight Gawain, but on closer inspection, the library’s medieval specialist Dr. Irène Fabry-Tehranchi realized it was the Suite Vulgate du Merlin.
The text fragment contains two scenes. The first depicts a decisive battle between Britons and Saxons: the Battle of Cambénic, where King Arthur’s nephew Gawain fights alongside his father and defeats four Saxon kings. The second scene takes place at the court on Ascension Day, when Merlin appears disguised as a blind harpist. Among other things, the story clearly shows how magic, Christian symbolism and court etiquette were intertwined in the medieval imagination.
New technology revealed the text
Following the discovery, a collaboration between the library’s conservators and its Cultural Heritage and Image Laboratory (CHIL) began. The aim was to enable the text to be read without damaging the parchment. Using multispectral imaging, the researchers were able to photograph the text in different wavelengths, from ultraviolet to infrared light, to reveal faded and hidden areas. Minimal noise filtering was used to enhance weak layers of writing. Marginal notes and old stamps, such as those with the word “Huntingfield”, were thus brought out again.
To study the structure of the parchment, computerized tomography (CT) scanning was used, the same technique used in medicine and paleontology. By “X-raying” the bookbinding, the researchers were able to create a three-dimensional model of the folds, threads and layers of the parchment. Finally, hundreds of photographs were taken from different angles to create a digital model that allowed the sequence of the text to be followed – even where text was hidden under flaps or stitches. The result was a digital reconstruction where the handwriting could be analyzed as if it were unfolded.

Using this arsenal of techniques, the researchers managed to recreate a text that has been hidden for over 500 years. For literary scholars, the discovery means that a new fragment of the Arthurian legend has become available for analysis, as well as a technical insight into how older manuscripts were reused and embedded in new volumes.
Dr. Irene Fabry-Tehranchi emphasizes that the project is not only about the discovery of a single text, but also about the development of a methodology to rediscover hidden fragments in archives in other parts of the world.
King Arthur's heraldic arms: Three crowns
King Arthur, like Sweden later, is portrayed with three crowns as one of his main features, which he is said to have worn on his heraldic arms (see main image). Whether there is any historical connection to Sweden's coat of arms is pure speculation, but the fact is that the origin of Sweden's crowns is still shrouded in historical obscurity. Three crowns have been traced back by historians to at least King Magnus Eriksson and the 1330s, some eight hundred years after the reign of King Arthur.
