The Prayer book of Mary of Guelders. An international project around a magnificent manuscript.

Short introduction by Miranda Bloem, Radboud University Nijmegen, January 2017

Because of its fragile state, the Prayer book of Mary of Guelders in the State Library in Berlin has not been accessible for years. Now, in a unique collaboration between the Berlin State Library and Radboud University in Nijmegen, a research team has been formed, consisting of experts in the fields of medieval book illumination, text and devotion, book restoration and technical research. They will combine their knowledge and expertise by dealing with a large variety of questions. The chief aim is to restore the manuscript in a condition that will not only allow the expert to study the manuscript, but also will permit the book to be displayed to the public.

An important part of the research focuses on the material aspects of the book: studying the pigments, parchment and ink. Three researchers of the Rathgen Forschungslabor in Berlin are conducting research with Raman Spectroscopy and infrared reflectography. In the State Library itself, where the book is being kept, two restorers are providing a detailed description of the condition of the book. As Mary of Guelders’ book of prayers has been used quite intensively, the damage is extensive: the paint of some of the miniature illustrations has faded or disappeared altogether, and many pages have been torn. These vertical tears sometimes stretch across the entire length of the page, which has led to parts of the parchment becoming loose. If nothing will be done, it is not unthinkable that entire pages will eventually break down completely.

The contents of the manuscript will be examined closely, too. For instance, prof. dr. Johan Oosterman from the Nijmegen University will question why the Duchess Mary of Guelders chose certain prayers and devotional texts. New archival research will hopefully shine more light on Mary’s life in Guelders, while continuing her ties to the French court. Art historian Dr. Miranda Bloem is scrutinizing which illuminators where actively involved in the painting process and how they distributed their labour. She also conducts iconographic research to some of the rather obscure saints in the prayer book

In the meantime, preparations are made to exhibit the book at Museum Het Valkhof Nijmegen, in October 2018. This exhibition will not just focus on the book but also on how the research was conducted. For this reason, Dick van Aalst, photographer and filmmaker, is tasked with capturing the project on film (the first results of his work can be viewed in a recently published video). During the years leading on to the exhibition, the general public and other researchers will be able to follow closely the investigation and learn about the dilemmas the researchers have been facing, about their accomplishments but also about the points where they got stuck. The aim is to be as transparent about the research project as possible, to be open in our communication and show how academic research is conducted.
