Have you ever been intrigued by the survival of fragments of medieval manuscripts, used perhaps as waste in later bookbindings, or damaged in catastrophic events such as the Ashburnham House fire? The recent launch of Fragmentarium (the Digital Research Laboratory for Medieval Manuscript Fragments) will enable many of these fragments to be analysed in greater detail, and in some cases to be digitally reunited. The British Library is one partner in this project, alongside institutions and collections from Austria, France, Germany, Greece, Italy, Norway, Switzerland, the USA, the Vatican and the United Kingdom. As the project states, 'Fragmentarium enables libraries, collectors, researchers and students to publish images of medieval manuscript fragments, allowing them to catalogue, describe, transcribe, assemble and re-use them.'

Some of our readers may have come across the story of the Ashburnham House fire of 23 October 1731. This tragic event left a number of manuscripts in the famous collection of manuscripts assembled by Robert Cotton in an extra-crispy state. After a remarkable conservation effort undertaken in the 18th and 19th centuries, many of these volumes did not look so bad, all things considered, as you can see for yourself with Beowulf. But some of these manuscripts did not fare so well — to the naked eye they often resemble something approaching a burnt biscuit!

Cotton MS Otho A X, f. 1v, as it looks in person

The burnt Cotton fragments are among the most evocative artefacts of medieval culture, both for the tragedy of their destruction and the mystery of their contents. Many of the surviving leaves remain critical to scholarship, often containing unique texts or their earliest known copies. Work on other fragments at the British Library has already shown that multispectral photography can make it possible to extract more information from what survives. The burnt leaves remain vulnerable, and so it is critical that digital techniques be used to document and preserve their present state.

Cotton MS Otho A X, f. 1v: a blend of photographs taken across light spectra

For several decades, technology has been applied to improve the readability of the Cotton fragments. In the early 1950s, ultraviolet photography was applied to Æthelweard’s Chronicle (in Cotton MS Otho A X and Cotton MS Otho A XII) in order to make new sense of a handful of pages. The same process was also used with Cotton MS Otho A I. At the time, however, these photographs did not achieve wide dissemination due to the limitations of publishing in print.

Multispectral imaging setup at the British Library

The recent application of multispectral photography has enabled us to recover more details of these fragments, and with reconstructed colour. At the same time, regrettably but inevitably, this technology has revealed that, in the course of half a century, the condition of these fragments has sometimes deteriorated. A few volumes that seemingly could be read without technological assistance only a few decades ago have details that today are difficult to read with the naked eye. In some cases, the volumes are so fragile that they can only be issued in the British Library's Manuscripts Reading Room with special curatorial permission.

We are currently publishing key remnants of some of the burnt Anglo-Saxon manuscripts in the Cotton collection on Fragmentarium. Dr Christina Duffy, the British Library's Imaging Scientist, has photographed over a hundred of these fragments and has skilfully processed them to make their reconstruction as legible as possible. The results will be available under a Creative Commons Public Domain Dedication. Fragmentarium has also built the capacity into their site to handle multiple images of a single folio — rare but critical functionality for dealing with multispectral imaging, since the images you will see are a scientific but also very much a human reconstruction.
