The investigation and conservation of the Vienna Genesis, a Late Antique manuscript on purple parchment, included the study of parchment production and purple dyeing in the sixth century. The process of parchment making and of purple dyeing was recreated and compared with the Vienna Genesis and other manuscripts from the sixth and eighth centuries. Parchment made from the hides of young lambs and dyed with orchil resembled the folios of the Vienna Genesis. The results of material analysis and the study of parchment technology influenced decisions for the conservation and storage of the manuscript. Fragile areas of ink and parchment were stabilised with strips of adhesive coated Japanese tissue paper. The single folios are stored in folders of Japanese paper and museum matboard within a sink mat.Die Untersuchung und Konservierung der Wiener Genesis, einer spätantiken Purpurhandschrift, beinhaltete eine Studie zur Herstellung von Pergament und zur Purpurfärbung im sechsten Jahrhundert. Der Prozess des Pergamentmachens und des Färbens mit Purpurfarbstoffen wurde in Experimenten rekonstruiert und die Ergebnisse mit der Wiener Genesis und anderen Handschriften des sechsten und achten Jahrhunderts verglichen. Aus den Häuten junger Lämmer hergestelltes und mit Flechtenfarbstoff gefärbtes Pergament ist den Folios der Wiener Genesis ähnlich. Die Erkenntnisse aus Materialanalyse und technologischen Studien beeinflussten Entscheidungen zur Konservierung und Aufbewahrung der Handschrift. Fragile Stellen in Tinte und Pergament wurden mit Brücken von beschichtetem Japanpapier stabilisiert. Die einzelnen Folios werden in Umschlägen aus Japanpapier und Museumskarton in versenkten Passepartouts aufbewahrt.

This article focuses on research into two ways of repairing holes found on parchment of Late Antique manuscripts. Their appearance and the reasons for these repairs are analysed and illustrated using the example of the Vienna Dioscorides, a Byzantine manuscript dated to 512. The reconstruction of the manufacturing method of thin Late Antique parchment prepared from lambskins shows clearly that these repairs were an important part of the production process and not subsequent repairs. Conservation of parchment may in some cases have a serious effect on the perception of this important technological evidence.

Compiled around the turn of the eighth century, in the Wearmouth-Jarrow monastery in Northumbria, the Codex Amiatinus is the oldest complete Vulgate translation that remains extant in one volume. T...

Biocodicology, the study of the biological information stored in manuscripts, offers the possibility of interrogating manuscripts in novel ways. Exploring the biological data associated to parchment documents will add a deeper level of understanding and interpretation to these invaluable objects, revealing information about book production, livestock economies, handling, conservation and the historic use of the object. As biotechnological methods continue to improve we hope that biocodicology will become a highly relevant discipline in manuscript studies, contributing an additional perspective to the current scholarship. We hope that this review will act as a catalyst enabling further interactions between the heritage science community, manuscript scholars, curators and conservators.

Medieval manuscripts, carefully curated and conserved, represent not only an irreplaceable documentary record but also a remarkable reservoir of biological information. Palaeographic and codicological investigation can often locate and date these documents with remarkable precision. The York Gospels (York Minster Ms. Add. 1) is one such codex, one of only a small collection of pre-conquest Gospel books to have survived the Reformation. By extending the non-invasive triboelectric (eraser-based) sampling technique eZooMS, to include the analysis of DNA, we report a cost-effective and simple-to-use biomolecular sampling technique for parchment. We apply this combined methodology to document for the first time a rich palimpsest of biological information contained within the York Gospels, which has accumulated over the 1000-year lifespan of this cherished object that remains an active participant in the life of York Minster. These biological data provide insights into the decisions made in the selection of materials, the construction of the codex and the use history of the object.

Tissue-thin parchment made it possible to produce the first pocket Bibles: Thousands were made in the 13th century. The source of this parchment, often called “uterine vellum,” has been a long-standing controversy in codicology. Use of the Latin term abortivum in many sources has led some scholars to suggest that the skin of fetal calves or sheep was used. Others have argued that it would not be possible to sustain herds if so many pocket Bibles were produced from fetal skins, arguing instead for unexpected alternatives, such as rabbit. Here, we report a simple and objective technique using standard conservation treatments to identify the animal origin of parchment. The noninvasive method is a variant on zooarchaeology by mass spectrometry (ZooMS) peptide mass fingerprinting but extracts protein from the parchment surface by using an electrostatic charge generated by gentle rubbing of a PVC eraser on the membrane surface. Using this method, we analyzed 72 pocket Bibles originating in France, England, and Italy and 293 additional parchment samples that bracket this period. We found no evidence for the use of unexpected animals; however, we did identify the use of more than one mammal species in a single manuscript, consistent with the local availability of hides. These results suggest that ultrafine vellum does not necessarily derive from the use of abortive or newborn animals with ultrathin hides, but could equally well reflect a production process that allowed the skins of maturing animals of several species to be rendered into vellum of equal quality and fineness.
