Recovering Fourteenth-Century Text from Chemical Reagent Damage*

In recent weeks, our Lincoln Record Society-funded PhD student, Jessica Holt, has been working with Dr Nicholas Bennett of the Lincoln Record Society, the University of Lincoln’s Conservation Team, Lincoln Cathedral and the Lincolnshire Archives. Using multi-spectral imaging, they have managed to recover lost text in the registers of Bishop Thomas Bek of Lincoln (1342-1347).

During the nineteenth century, canon G. G. Perry applied a chemical reagent to several folios from MS. 209, a late fourteenth-century manuscript held at the library at Lincoln Cathedral. (5) This manuscript contains one of the only two surviving copies of Richard Rolle’s Officium et Miracula. (8)Regrettably the chemical reagent caused irreparable damage and rendered some of its’ text illegible as evidenced in the image of f.3 r. below. Perry was later named and shamed for his deed in 1866 in an edition of the Early English Text Society. (3)

The challenge of trying to decipher faded court hand is not unfamiliar for those working directly with manuscripts. Whilst today, UV lamps can be used to combat this problem, researchers in the nineteenth century were forced to seek out another solution. (4) Several attempts were made using different chemical reagents to enhance the legibility of metallic inks. (1) Contrary to their original intent, however, these substances have now rendered many documents unreadable, as these substances later darkened, coating their original texts with dark brown, black, or, in some cases, blue staining. Of these chemical reagents the most common were:

  • Tincture of Oak Gall (an alcohol-based tincture that utilises essence of oak galls)
  • Sulphuric Tinctures (mixtures typically comprised of calcium carbonate, calcium polysulphide, and calcium sulphate)
  • The ‘Giobert Tincture’ (mixture comprised of water, hydrochloric acid, and potassium hexacyanoferrate) (1)

Despite the clear damage these substances were causing to manuscripts across the course of the nineteenth century, these methods continued to be used as late as 1914, when Hugo Deunsing and Martin Flasher applied sulphuric tinctures to manuscripts stored in the library of the Orthodox Patriarchate in Jerusalem. (1)

Doctoral student, Jessica Holt, was forced to grapple with the damage caused by these chemical reagents when examining the registers of Bishop Thomas Bek of Lincoln (1342-1347). It quickly became apparent that several folios of register 6 had been damaged by an unknown nineteenth-century reagent. (6) Hope, however, laid with a technique known as multi-spectral imaging (MSI). MSI is a non-invasive scientific imaging technique that can be applied to manuscripts to recover lost text. (2, 7) This technique was also successfully used by the British Library in 2017 to recover script lost through fire damage, natural degradation, and chemical damage. (2) With the kind permission from the bishop of Lincoln, Lincoln Cathedral, and the Lincolnshire Archives, and the wonderful support of Claire Arrand, Dr Nicholas Bennett, and Professor Louise Wilkinson, we were able to transfer register 6 from the Lincolnshire Archives to the University of Lincoln, where we were able to use MSI to successfully recover the contents of the lost text with aid from Dr Philip Skipper and the conservation department.

Regrettably, unlike the damage caused to f.3 r. of MS. 209, the identity of the culprit has been lost to time. The positive results of MSI ultimately present an optimistic future for other researchers examining manuscripts similarly altered by nineteenth-century reagents.

Jewish Life in the Middle Ages: Lincoln and Beyond – A University QR Collaborations Project with the Lincolnshire Archives

Lincoln was home to an important and vibrant Jewish community in the twelfth and thirteenth centuries. Fortunately for us, this community has left behind a remarkable trail of evidence in our national and regional archives. Past histories of Lincoln’s Anglo-Jewish community have been dominated by the story of Little Hugh of Lincoln, for whose death 19 innocent Jews were executed in 1255. While evidencing the increasingly difficult circumstances in which the Anglo-Jewry lived prior to their expulsion from England in 1290, the surviving records provide some fascinating insights into the dynamics of Jewish life, the Jews’ religious, social and business interactions with one another, and their encounters with their Christian neighbours, the Cathedral clergy and the Crown’s officials.  

For many years now, Lincoln has been home to the Lincolnshire Archives, one of the UK’s largest regional collections, which preserves the manuscript records of the medieval city, cathedral and diocese of Lincoln. In 2023, Professor Louise Wilkinson of the Medieval Studies Research Group received funding from the University of Lincoln’s QR Collaborations Scheme for a pilot project to survey the archival holdings relating to the medieval Lincoln Jewry that are held locally. She received valuable assistance from Dr Dean Irwin, our visiting fellow, who acted as academic advisor, from Simon Neal, our archival researcher, and from Jessica Holt, our research assistant. The project surveyed and compiled a handlist of documents relating to the medieval Jewish community that are held in Lincoln. We also hosted a free talk and document workshop at the Lincolnshire Archives in June 2023 to showcase its remarkable collections. In the longer term, we hope that this initiative may aid long-standing plans for an exhibition that is warmly supported by the head of Lincoln’s Jewish community. 

A major output of our project has been the first handlist of documents held in the Lincolnshire Archives on the medieval Jewry. Simon Neal has produced English summaries of the Latin documents (some of which also contain Hebrew or have Hebrew records associated with them) that contain references to members of the medieval Jewish community. Simon worked carefully through a range of original single sheet deeds, as well as entries in cartularies and other miscellaneous documents. He also consulted microfilm copies and transcriptions of cartularies for Lincolnshire religious houses held elsewhere that are also available for readers to consult at the Lincolnshire Archives. The records of the Dean and Chapter of Lincoln Cathedral proved to be particularly fruitful, since they contain references to local Jewish families, their neighbours, their associates, their business partners and their residences. These include, for instance, a portion of a thirteenth-century chirograph that recorded the notification of a grant by Robert le Turnur to Jacob, son of Leo, a Jew of Lincoln, of some land in the parish of St Michael on the Mount, which lay next to Jacob’s house (Lincolnshire Archives, D&C, Dij/76/2/47). A notification of a grant by Lincoln’s famous female castellan, Lady Nicholaa de la Haye (d. 1230), to Peter the Woad Seller, of her land and houses in the parish of St Michael also carefully recorded how this property lay near the land formerly of Moses son of Benedict, a Jew of Lincoln (Lincolnshire Archives, D&C, Dij/76/2/22).

We are also grateful to Claire Arrand, Lincoln Cathedral’s Librarian, and to the staff of the Lincolnshire Archives for their assistance. 

There are also references among the documents in the Lincolnshire Archives to the properties of Jewish women like Belaset of Wallingford, who was hanged for clipping the king’s money (Lincolnshire Archives, D&C, A/1/8, fol. 107, no. 290), and Floria of London, who went into exile in Edward I’s reign (Lincolnshire Archives, D&C, Dij/75/2/27). In fact, there are some extremely interesting post-1290 grants of former Jewish property that enrich our understanding of the local context of the sad events surrounding the Expulsion.
