Everyone has heard of King Arthur, but 90% of medieval manuscripts of chivalry and heroism have been lost, confirms new research

New ecological-literary research confirms huge loss to history of chivalric stories

• Six in ten medieval stories in English have been lost
• More than 75% of tales in German, Icelandic and Irish survive, with unusual distribution patterns for Icelandic and Irish

New research released today finds that, while the Knights of the Round Table have won global fame, most medieval heroic or chivalric stories in English have been lost. Meanwhile, more than three quarters of medieval stories in Icelandic and Irish survive to the present, in an unusual pattern suggesting island ‘ecosystems’ helped preserve culture.

The findings come from an international research team, including Oxford experts, which has applied statistical models used in ecology to estimate the loss and survival of precious artefacts and narratives from different parts of Europe. This ecological approach offers a new perspective on the loss of cultural heritage, complementing past research. Their findings are published in the journal Science, with Mike Kestemont (University of Antwerp) and Folgert Karsdorp (KNAW Meertens Institute) as the main authors.

Dr Katarzyna Anna Kapitan, an Old Norse philologist and Junior Research Fellow at Linacre College, Oxford, says, ‘By using statistical methods borrowed from ecology, we were able to add to previous scholarship.

‘We estimate that more than 90% of medieval manuscripts preserving chivalric and heroic narratives have been lost. This corresponds roughly to the scale of loss that book historians had estimated using different approaches. Moreover, we were able to estimate that some 32% of chivalric and heroic works from the Middle Ages have been lost over the centuries.’

The team used ‘unseen species models’ from ecology to gauge the loss of narratives from medieval Europe, such as romances about King Arthur, or heroic legends about Sigurd the dragon slayer or the legendary ruler Ragnar lóðbrok, known to wider audiences from the TV series Vikings. The estimates of loss and survival they obtained are compatible with the scant historical evidence.

The study revealed significant differences in survival rates for medieval works and manuscripts in different languages, suggesting that Irish tradition of medieval narrative fiction is best preserved, while works in English suffered the most severe losses. The team calculated that around 81% of medieval Irish romances and adventure tales survive today, compared to only 38% of similar works in English. Similarly, results suggest that around 19% of medieval Irish manuscript books survive, compared to only 7% of English examples.

Dr Daniel Sawyer, Fitzjames Research Fellow in Medieval English Literature at Merton College, Oxford, says, ‘We found notably low estimated survival rates for medieval fiction in English. We might blame the dissolution of the monasteries under Henry VIII, which did scatter many libraries. But heroic stories in English rarely appear in the library catalogues of monasteries and friaries in the first place.’

‘Another possible explanation might be found in the limited prestige of the English language during this period’, Dr Sawyer continues. ‘Today, English is learned as a second language all over the world, but during the Middle Ages it had little international significance. After the Norman Conquest, in particular, French was important in England as an international language of power and culture, and the English crown owned parts of what is now France.

‘In fact, if we add fiction written in Norman French in England to the evidence in English, the survival rate for English evidence looks more like the rates for other languages. This shows the importance of Norman French to English culture, and suggests that heroic stories in Norman French and in English formed a connected tradition.’

Meanwhile, Dr Kapitan explains it is a very different picture for Iceland, where ‘we know today around three out of four medieval Icelandic romances and adventure tales (or 77%), but only one out of six medieval manuscripts preserving these works (17%)'.

Besides events such as library fires and the recycling of books, the research identifies the original ‘evenness’ of cultural production as an overlooked factor in the survival of ancient artefacts.

Dr Kapitan says, ‘Our research has revealed interesting similarities between Icelandic and Irish evidence. Icelandic and Irish literatures both have high survival rates for medieval works and manuscripts, and also very similar “evenness profiles”. This means the average number of manuscripts that preserve medieval works is more evenly distributed than in other traditions we examined.’

‘The similarities between Iceland and Ireland may be caused by lasting traditions of copying literary texts by hand long after the invention of print,’ explains Dr Kapitan.

Dr Sawyer adds, ‘The evidence might tell us about England’s ties to continental Europe in the Middle Ages, and about the influence of wider European culture on English writing. England’s size and its very close links to the continent could explain why the English evidence doesn’t display the evenness found in the island distributions of stories in Iceland and Ireland.’

These analyses call for a wider application of these methods across the heritage sciences. The researchers agree that the collaboration between disciplines has been very stimulating. As Dr Kapitan concludes, ‘This shows how trans-disciplinary research lets us step beyond anecdotal case-studies of single scribes or texts, and allows large comparisons across different places, traditions, and languages.’
