Abstract

The Great Parchment Book of the Honourable The Irish Society is a major survey, compiled in 1639 by a Commission instituted by Charles I, of all the estates in Derry, Northern Ireland, managed by the City of London through the Irish Society and the London livery companies. Damaged in a fire at London’s Guildhall in 1786, it has been unavailable to researchers for over 200 years (Moody; Curl). The damaged manuscript has however remained part of the City of London’s collections held at London Metropolitan Archives (LMA). As part of the commemoration of the 400th anniversary of the building of Derry’s city walls in 1613, it was decided to attempt to make the document available as a central point of the planned exhibition. The book represents an important source for the City’s role in the colonization and administration of Ulster and, given the relative paucity of archival records for early modern Ireland, the manuscript should also reveal key data about landholding and population in 17th-century Ulster.

This ambitious project has attracted support from several funders, including the UK’s National Manuscripts Conservation Trust, the Marc Fitch Fund, the Engineering and Physical Sciences Research Council (EPSRC), a number of London livery companies and the Irish Society itself. University College London (UCL), Derry Heritage and Museums Service (DHMS), and LMA have also provided funds and staff time.

Physical Description and Conservation Issues

The manuscript consists of 165 separate parchment membranes, all damaged in the fire. Uneven shrinkage and distortion has rendered much of the text illegible.

Traditional conservation alone would not produce sufficient results to make the manuscript accessible or suitable for exhibition, the parchment being too shriveled to be returned to a readable state. Much of the text is visible but distorted; following discussions with conservation and imaging experts, it was decided to flatten the parchment sheets as far as possible, and to use multi-modal digital imaging to gain legibility and enable digital access.

The Project

A partnership with the Department of Computer Science and the Centre for Digital Humanities at UCL established a four-year EngD in the Virtual Environments, Imaging and Visualization programme in September 2010 (jointly funded by the EPSRC and LMA) with the intention of developing software that would enable the manipulation (including virtual stretching and alignment) of digital images of the book rather than the object itself. The aim was to make the distorted text legible, and ideally to reconstitute the manuscript digitally.

Conservation work on the membranes encompassed cleaning, humidification, and tension drying, using magnets placed on top of the parchment above a metal sheet to hold creases open during the drying process. This opened out areas of parchment where the camera could not reach the text (De Stefani).

The practical conservation of the membranes was the essential first step, followed by the imaging work being carried out by UCL, where a set of typically 50-60 22MP images is captured for each page and used to generate a 3D model containing 100-170MP, which allows viewing at archival resolution (Pal et al., 3D Reconstruction). These models can be flattened and browsed virtually, allowing the contents of the book to be accessed more easily and without further handling the document (Pal et al., Interactive Exploration; Pal et al., Interactive Restoration). A readable and exploitable version of the text has also been prepared, comprising a searchable transcription and glossary of the manuscript. This element of the project received a grant from the Marc Fitch Fund towards the employment of a palaeographer who also encoded appropriate terms using TEI to capture structural and semantic information about the texts enabling comprehensive searching of the document.

The transcript and images of the document have been published online. The project worked with web-designers Headscape to develop a website to enable sophisticated online presentation and searching of the document contents.

From 2013, both DHMS and LMA plan to use the document in their interpretation and outreach programmes, developing resources for schools and colleges based on the information it contains; there is also considerable interest from academics (Stewart 2013a; Stewart 2013b). Our work on the computational approach to model, stretch, and read the damaged parchment will be applicable to similarly damaged material as we believe we are developing best practice computational approaches to digitizing highly distorted, fire-damaged, historical documents.

Summary

The digital imaging and transcription will provide a lasting resource for historians researching the Plantation of Ulster in local, national and international contexts. The progress of the project is being recorded on a blog embedded in the website. (The Great Parchment Book).
