Counting Sheep: Potential Applications of DNA Analysis to the Study of Medieval Parchment Production

This chapter follows up on several preliminary tests that have shown that DNA survives in medieval parchment manuscript leaves and may be extracted and analyzed, and offers suggestions for defining and implementing future genetic studies of parchment. It articulates the need to consider genetic data in conjunction with other types of evidence—such as historical texts and archaeological data—both in planning tests of parchment and in interpreting the results of such tests. I consider the potential influences of diet, urbanization, market and trade specialization, and changes in agricultural practices and animal husbandry on parchment production, and discuss how genetic analysis can contribute to our knowledge of these topics as well as how historical and archaeological evidence will both complicate and contextualize data derived from genetic testing

Digital Restoration of Damaged Historical Parchment

In this thesis we describe the development of a pipeline for digitally restoring damaged historical parchment. The work was carried out in collaboration with London Metropolitan Archives (LMA), who are in possession of an extremely valuable 17th century document called The Great Parchment Book. This book served as the focus of our project and throughout this thesis we demonstrate our methods on its folios. Our aim was to expose the content of the book in a legible form so that it can be properly catalogued and studied. Our approach begins by acquiring an accurate digitisation of the pages. We have developed our own 3D reconstruction pipeline detailed in Chapter 5 in which each parchment is imaged using a hand-held digital-SLR camera, and the resulting image set is used to generate a high-resolution textured 3D reconstruction of each parchment. Investigation into methods for flatting the parchments demonstrated an analogy with surface parametrization. Flattening the entire parchment globally with various existing parametrization algorithms is problematic, as discussed in Chapters 4, 6, and 7, since this approach is blind to the distortion undergone by the parchment. We propose two complementary approaches to deal with this issue. Firstly, exploiting the fact that a reader will only ever inspect a small area of the folio at a given time, we proposed a method for performing local undistortion of the parchments inside an interactive viewer application. The application, described in Chapter 6, allows a user to browse a parchment folio as the application un-distorts in real-time the area of the parchment currently under inspection. It also allows the user to refer back to the original image set of the parchment to help with resolving ambiguities in the reconstruction and to deal with issues of provenance. Secondly, we proposed a method for estimating the actual deformation undergone by each parchment when it was damaged by using cues in the text. Since the text was originally written in straight lines and in a roughly uniform script size, we can detect the the variation in text orientation and size and use this information to estimate the deformation. in Chapter 7 we then show how this deformation can be inverted by posing the problem as a Poisson mesh deformation, and solving it in a way that guarantees local injectivity, to generate a globally flattened and undistorted image of each folio. We also show how these images can optionally be colour corrected to remove the shading cues baked into the reconstruction texture, and the discolourations in the parchment itself, to further improve legibility and give a more complete impression that the parchment has been restored. The methods we have developed have been very well received by London Metropolitan Archives, as well the the larger archival community. We have used the methods to digitise the entire Great Parchment Book, and have demonstrated our global flattening method on eight folios. As of the time of writing of this thesis, our methods are being used to virtually restore all of the remaining folios of the Great Parchment Book. Staff at LMA are also investigating potential future directions by experimenting with other interesting documents in their collections, and are exploring the possibility of setting up a service which would give access to our methods to other archival institutions with similarly damaged documents

Finding Words: The Ligatus Glossary Project

All crafts, trades and disciplines sooner or later develop their own specialist vocabularies to allow their practitioners to communicate quickly, easily and clearly when going about their everyday activities. In the more literate areas of life – medicine and law for instance – these vocabularies have survived and remain, if not in use, at least in older records, but the more artisan trades have often lost their words as techniques have changed and new ways of doing things have evolved. This is certainly the case with bookbinding, where our current, inherited vocabulary has shown itself quite unable to cope with the description of the detailed techniques and structures of books sometimes no more than two hundred years old. Even where terms have survived, the same terms have sometimes been used to mean different things, or different things have been included under the same term. As the study of the history of bookbinding develops, and its value as an essential but hitherto largely disregarded part of the history of the book becomes ever clearer, so the need for a consistent glossary of terms becomes ever more apparent. The Ligatus Glossary project is trying to supply this need, working with the old terms and inventing new ones in equal measure, and delivering the result on-line in a new, hierarchical schema designed around the structure of the book itself, in an attempt to pin down the extraordinary diversity of technique used over two millennia to make the tens of millions of books that fill our libraries

The genealogy of the king of Scots as charter and panegyric

When we think of genealogies in medieval Scotland our minds might turn at once to Gaelic, the Celtic language that was spoken in the Middle Ages from the southern tip of Ireland to the northernmost coast of Scotland. This is not unnatural. Texts that trace the ancestry of a notable individual generation by generation survive in their hundreds from the medieval Gaelic world. They are found today almost exclusively in late-medieval Irish manuscripts. Some genealogies originated in collections made as early as the tenth century. Presumably there were once many Scottish manuscripts containing genealogies, too. A reason why they would not have survived is that, in the Scottish kingdom during the twelfth and thirteenth centuries, the Gaelic learned orders who would have had a primary interest in writing and copying this material declined in significance and ceased to participate in Gaelic literate culture. This chapter will open with a brief survey of medieval genealogical texts relating to the Scottish kingdom, followed by a closer discussion of the limited number that are known to have existed between about 995 and 1250. Thanks to some recent insights about the physicality of texts, and the example of Bengali copper charters, a new approach to this material will be developed that offers a fresh perspective on the role of genealogy as a written expression of kingship and lordship

E-Scripture: The Impact of Technology on the Reading of Sacred Texts (2013)

The tradition of religious readers in transition is not new: Augustine expressed “amazement” that Ambrose read silently and not aloud, movable type in the fifteenth century made the Bible publishable without scribal work, and today, electronic pages have become interactive in ways scarcely imagined a short time ago. How readers of today imagine a page (now conceptualized as a ‘web-page’) and consequently, reading in general, has profound implications for the 21st century. Acknowledging the fact that “the significance of a religious book lies not only in the message of its content, but also in the form and self-presentation with which it makes itself available to worship and transmission,” this project assumes that a great deal of perspective is provided by looking at this current transition in light of the old. In virtually all previous reading transitions, a religious ‘pattern of reading technology’ can be seen, whose pieces are all well-known but have not been collectively applied to the current situation of e-reading. The pattern operates with a three part assumption: readers will initially use a new technology to perform the same functions as the old technology, only more quickly, with more efficiency, or in greater quantity. This early use of new reading technology, in other words, largely attempts to imitate the functions and appearance of the old format. The second part is that the old technology becomes sacralized or ritualized in the face of the new technology’s standardization. As this standardization occurs, the new technology develops its own unique and innovative functions, exclusive to that form and shedding some or most of the imitative appearance and functions of the old technology – the third part of the pattern. Reviewing these transitions of the past and present, it becomes clear that perhaps fear of the new technology – however relatable – proves somewhat unfounded. New reading technology does not prove ultimately inimical to the old formats, or to religion, and despite many initial practical concerns, actually provides a multitude of benefits in the reading of sacred texts

Plotting the Centre: Bramante’s Drawings for the New St. Peter’s Basilica

This paper examines the concept of 'centre' in the design and symbolism of the new St Peter's Basilica, executed by Donato Bramante in the early 16th century. Drawing upon theological and philosophical notions of centre in late Medieval and Renaissance culture (specifically Nicolas Cusanus), the study argues that Bramante's drawings for the project reveal a particular understanding of centre, and its constellations of sub-centres, that broadly follow Platonic cosmological principles highlighted in the Timaeus. The paper considers how this understanding of space was also communicated in the iconography of the frescoes in the Stanza della Segnatura in the Vatican Palace, executed by Raphael at the same time as Bramante's design for the new basilica, in which Bramante is also credited as the author of the perspective construction

Digitally reconstructing the Great Parchment Book:3D recovery of fire-damaged historical documents

The Great Parchment Book of the Honourable the Irish Society is a major surviving historical record of the estates of the county of Londonderry (in modern day Northern Ireland). It contains key data about landholding and population in the Irish province of Ulster and the city of Londonderry and its environs in the mid-17th century, at a time of social, religious, and political upheaval. Compiled in 1639, it was severely damaged in a fire in 1786, and due to the fragile state of the parchment, its contents have been mostly inaccessible since. We describe here a long-term, interdisciplinary, international partnership involving conservators, archivists, computer scientists, and digital humanists that developed a low-cost pipeline for conserving, digitizing, 3D-reconstructing, and virtually flattening the fire-damaged, buckled parchment, enabling new readings and understanding of the text to be created. For the first time, this article presents a complete overview of the project, detailing the conservation, digital acquisition, and digital reconstruction methods used, resulting in a new transcription and digital edition of the text in time for the 400th anniversary celebrations of the building of Londonderry’s city walls in 2013. We concentrate on the digital reconstruction pipeline that will be of interest to custodians of similarly fire-damaged historical parchment, whilst highlighting how working together on this project has produced an online resource that has focussed community reflection upon an important, but previously inaccessible, historical text

Vat. copt. 57: A Codicological, Literary, and Paratextual Analysis

MS Vatican City, Biblioteca Apostolica Vaticana Vat. copt. 57, a collection of homi- lies attributed to John Chrysostom in Bohairic Coptic, poses a number of challenges to scholars. Questions such as, Can we identify the texts, and what is their rela- tionship to their Greek models? Can we know who the copyist(s) was or were? are approached by a team of scholars in a collaborative stud

The ‘PAThs’ Project: An Effort to Represent the Physical Dimension of Coptic Literary Production (Third–Eleventh centuries)

PAThs – Tracking Papyrus and Parchment Paths: An Archaeological Atlas of Coptic Literature. Literary Texts in their Geographical Context. Production, Copying, Usage, Dissemination and Storage is an ambitious digital project based in Rome, working towards a new historical and archaeological geography of the Coptic literary tradition. This aim implies a number of auxiliary tasks and challenges, including classification of authors, works, titles, colophons, and codicological units, as well as the study and wherever possible exact mapping of the relevant geographical sites related to the production, circulation, and storage of manuscript
