First of all there is a need to clarify the heading. It is the Gospel according to St John, written by hand, on parchment, and bound into a book, once owned by St Cuthbert, and surviving to this day. It is not The Gospel according to St Cuthbert ~ there is no such thing. It is also known as the Stonyhurst Gospel. It spent some time in the library at Stonyhurst College.
The book is claimed to be the oldest surviving bound book in Europe, and possibly the world. It is now kept securely in the British Museum, and is regarded as too precious to be continuously displayed to the public. We are happy to record a few notes on it here, since we are keen to support craftspeople of all centuries, and also to demonstrate the long established and long-lasting properties of good work.
St Cuthbert's Gospel is a good example of what what might be called traditional codex bookbinding. Pages of text ~ assembled in order ~ folded into folios ~ gathered into sections ~ sewn on cords ~ worked headbands ~ bound between boards ~ covered in leather ~ appropriately decorated.
St Cuthbert died in 687, so the book is around thirteen centuries old. It has survived since then because it was interred with him. For some reason his coffin was opened four centuries later and the book was removed. Its significance was sufficiently recognized for it to have been treated with respect. Nor has anyone tried to preserve it by sticking loose pages back with adhesive tape. (Bookbinding novices please note: book preservation must be left to experts. Do not do anything to "repair" any old volume until you have qualified as a conservator, for which great knowledge and experience, spread over ten years or more, is required. The gospel in the photograph above would normally have been protected by holding it in a clean and cotton gloved hand, to prevent impurities, such as skin grease, from soiling it. Either the photograph was taken before the museum bought it, or a dispensation was made for this picture. Those are the sorts of matters that conservators insist upon.)
