Why would certain passages from an ancient horoscope and related predictions be smudged and partially erased? This is what researchers are currently trying to determine using multi-spectral images recently captured of Papyrus 98.

Papyrus 98 (British Library Pap. XCVIII) is fully digitised and can be viewed online here.

The British Library holds over 3000 papyri, along with several thousand unframed fragments. Western Heritage Collections cares for our Greek and Latin papyri, while papyri in other languages are found in our Asian and African Collections. The papyri collections are sequentially numbered running from Papyrus 1 – Papyrus 3136 with a separate sequence of 37 items forming the Egerton Papyri collection.

Papyrus 98 underwent multi-spectral imaging to improve legibility on some partially erased and smudged passages. Papyrus 98 is housed in a glass enclosure with inscriptions visible on both the recto and verso. The original collector was most interested in the Funeral Oration of Hyperides over Leosthenes and his comrades in the Lamian war [BC 323] which was placed in the recto position at the front of the glass frame. This partially imperfect Greek text is thought to date to 1/2 century CE with the greater portion of the oration in fourteen columns. However, it has since been discovered that it is on the verso of the current housing where the oldest and first text was inscribed on the papyrus.

Due to the long profile, multi-spectral imaging of Papyrus 98 was achieved by imaging the manuscript in sections and digitally stitching the images together.

On this 'verso' side is an astrological treatise consisting of three and three-quarter columns of a Greek language horoscope partially in small uncial characters similar to those of Hyperides. This is followed by an Egyptian language set of predictions relating to the horoscope written in cursive handwriting in what is referred to as 'the Old Coptic Script'. The Papyrus 98 manuscript showcases the earliest example of this Old Coptic Script.

The overall majority of the Greek text in this manuscript is in excellent condition, with the exception of the partially erased sections at the bottom of column III and IV which precede the lines in which the Egyptian language section begins. Other areas of faded or partially rubbed out sections were also identified and hoped to be recovered with multi-spectral imaging.

Researchers are still going through the results trying to figure out why these particular passages were erased and what was, or is, the significance of the obscured text. While the raw images have provided some clarity in certain areas, there are several algorithms which will be run on the data set to isolate and enhance the blurred regions. This is just one of many projects that our conservation team are working on to aid scholarly research and enable further access through digital means.

A small number of British Library papyri have been digitised in full and can be viewed on Digitised Manuscripts. Further information about published papyri can be found on the Trismegistos database. More about this collection item can be found on the Explore Archives and Manuscripts resource, while further information about our Greek and Latin papyri collections can be found here.

Liz Rose, Textile Conservator

The conservation process is always a very special time for the item under repair. It is a time during which normally concealed elements of the object are exposed offering a unique opportunity to understand the processes involved in the making of the item. This is even more apparent when conserving books. Books are complex three dimensional objects and for this reason the conservator’s decision-making process can be extremely challenging.

The following examples show how important it is to record every step in the conservation process and to be able to discuss findings made along the way with other experts. This enables us to fully understand and consequently be able to retain and share the information uncovered during all stages of the work. For the past three years I have been working as Manager of the Conservation Studio for the British Library Qatar Foundation Partnership. I have worked with a rich and heterogeneous variety of library material ranging from archival files to ancient scientific Arabic Manuscripts. This material has been arriving on our benches for digitisation preparation and for more extensive conservation.

A group of sixteen manuscripts was identified as being relevant for the Qatar Digital Library Portal during scoping for the second phase of the project. This portal is where our project team upload digitised material. The sixteen manuscripts are a small fraction of the so called Delhi Collection; a vast collection of more than 2,900 manuscripts held here at the British Library. The manuscripts are written in various languages and historically thought to have come from the Royal Mughal Library in Delhi.

The manuscripts are in very poor condition and housed in conservation boxes. The books were transported from Delhi to Calcutta and faced many perils on their journey to the India Office Library in London. They were eventually transferred to their current home here at the British Library, but have never been conserved. This is quite a unique situation since in the past few centuries vast campaigns of restoration and re-binding have irremediably transformed much of our library collections. During these campaigns original bindings were often removed. This resulted in a loss of historical evidence relating to the use and provenance of the volumes.

The subject of this piece is the recent conservation work carried out on two of these manuscripts to enable their imminent digitisation.

Left: Delhi Arabic 1902. Right: Delhi Arabic 1937B.

These manuscripts contain collections of mathematical treatises dating possibly to the XIX and have been heavily damaged by insects and centuries of use and abuse. The treatments conservators apply to items of historical value should always follow a series of ethical guidelines that standardise our profession. Those guidelines are based on one main principle called ‘minimal approach’. ‘Minimal’ doesn't mean less time doing the work or small in the sense of the amount of money spent for the treatment; ‘minimal’ refers to minimal intervention.

The conservator must work with great attention to detail ensuring that historically relevant physical features in the binding, sewing and substrate remain intact and undisrupted. Our work in the British Library Qatar Foundation Partnership Conservation studio is primarily preparation for digitisation. This means we focus on making items fit for withstanding the imaging process. This is both to ensure safe handling of the object and to enable the creation of a good quality surrogate.

Books are very challenging items to reproduce digitally and are often tightly bound. Each page needs to be carefully photographed and the text needs to be entirely visible and legible. The aim of a good quality online surrogate is to give users a truthful virtual experience of the item in its entirety, that is, in the case of bound volumes, much more than the mere text written on its pages.

Delhi Arabic 1902 and 1937B required conservation work because they were too fragile to be safely handled. It would have been impossible to achieve full legibility due to the poor state of their pages. Pages laced with insect holes were repaired with very thin toned Japanese tissue paper and the weak sewing of the book block was reinforced. Every piece of the book structure such as the remnants of the threads used to create the end bands or the sewing of the book-block were supported and secured where they were originally.

The leather covers proved to be a completely different challenge on their own. As soon as they were closely examined it became clear that the boards for both the books were created with layers of reused manuscript fragments.

The layers constituting the boards in manuscript Delhi Arabic 1902 were already delaminating and the adhesive used to stick them together was failing. During discussions with the curators it was decided to completely separate the layers forming the boards and to not re-use the leather cover any more due to its fragility.

Each layer of the newly found manuscript was easily lifted with the help of a spatula before re-housing in Melinex folders. Numbering was applied to each envelope recording the sequence of the original layering, and subsequently all envelopes were housed in two separate four flap folders to identify the left from the right board. The writing style and content of these manuscript fragments is currently under study and has not yet been identified. It will add interesting information about Delhi Arabic 1902 and help to date the cover and possibly to identify the geographical area where it was made.

Layers of manuscript fragments are easily lifted and housed in Melinex numbered envelopes.

New conservation boards were prepared and inserted into the now “empty” leather cover. A piece of Plastazote was cut to size and used as a substitute for the now removed book-block in order to hold the leather. The leather cover was wrapped in Melinex to protect it during future handling.

A new light board limp cover was created for the book-block after all the pages had been repaired and the sewing reinforced.

The now separated parts of the manuscript were housed together in a drop back spine box made to size.

All the separated parts of the manuscripts are housed together in the box.

 

The cover of the second manuscript, Delhi Arabic 1937B, also showed evidence of fragments (from possibly the same manuscript) used to make its boards, but in this case a different method was devised for the overall conservation of the book.

In this case only one layer, on both of the boards, transpired to be made of reused written paper. For this reason it was decided that the boards and the cover, also detached and delaminating, would not have to be dismantled. Instead they would be imaged and later re-composed to be re-attached, as originally was, with the book-block.

The losses of leather on the spine and on the edges of the boards were filled with new goat archival leather and all the fragments of the old leather and the decorated paper were re-adhered where they were originally. Interesting features were in this way preserved for posterity, for example the covering leather that was applied to the spine, along the edges, and on the corners of the boards in thinly pared pieces retained its overlapping appearance.

Small remnants of strips of blue decorative paper were consolidated and adhered along the perimeters of the decorative marbled paper.

The arrows indicate small remnants of decorative blue paper strips that were originally forming a frame, now overlapping the decorated marbled central piece.

 

Our meticulous method of working enables us to provide scholars who are interested in all aspects of the volume, not just the content, with as much information as possible. This attention to detail potentially protects clues to a past we can only imagine.

Conservator Flavio Marzo reports on his fascinating findings during the conservation of one of the books bearing the presumed signature of William Shakespeare.

As it is now the 400th anniversary of the death of William Shakespeare and the British Library has unveiled a major exhibition about the Bard of Avon, I thought it was a good time to share the conservation work I carried out on one of the items currently on exhibition. In 2005 I was given the opportunity to work on an item here at the British Library bearing one of the few surviving (possible) signatures of the poet. The book, possibly part of Shakespeare’s personal library, is a copy of “The Essayes of Morall, Politike and Militaire Discourses” written by Michaell Montaigne and published in London in 1603. The volume was sent to the conservation studio to be treated before being sent out on a loan and presented some very interesting and unusual features.

The Examination

The cover and the book block were detached and the main task was to secure them together ensuring that any treatment was clearly visible and unobtrusive.

Left: Front cover. Right: Cover and book block detached.

The sewing of the body of the book, most likely the result of a quite recent restoration campaign, was made on five narrow strips of tanned brown leather. Probably at the same time new end leaves were added and secured to the first and last sections through an over-casted stitching. There was no evidence of spine lining or glue applied to the spine. When the cover was removed the original sewing supports remained laced through the boards and the page with Shakespeare’s presumed signature was attached on the inside of the left board.

The inside of the detached cover with the signature page and the original supports laced with the cover.

The original sewing supports were made of strips of alum tawed leather with a second layer of tanned brown leather added to give thickness to the raised bands ensuring their visibility on the spine of the book.

Left (viewing from the inside): A strip of alum tawed leather with clear distortions due to the original passages of the thread of the original sewing. Right (viewing from the outside): One of the trimmed tanned leather strips used to create the raised effect on the spine cover.

Areas of the leather cover were missing at the head and tail. After a thorough examination of the cover I realised that the page bearing the signature, adhered onto the inside of the left board, was not originally attached as a paste down, and in fact was never originally placed at the beginning of the book. Careful visual examination revealed that a raised oval was showing through the page.

An image of the page taken with raking light clearly showing an oval shaped imprint from the recto of the page.

Since the page was adhered to the board along the edges only, it was possible to insert a light sheet between the page and the board. Under transmitted light it was possible to capture an image of what became clearly identifiable as a British Museum stamp - proving that this sheet was, until quite recently, still detached. Under transmitted light it was also possible to locate and record the watermark present on this page.

Left: British Museum stamp imaged with transmitted light. Right: Watermark of the page with the signature.

This watermark was subsequently compared with others found on the pages within the book block. Although no perfect match was found between the watermarks, there was a very strong similarity between them.

Other watermarks found within the book block.

Another detail that immediately caught my attention was the observation that the damages along the edges of this sheet did not match the losses and tears present along the edges of the first page of the book.

Mapping of the stains and damages show how different and inconsistent they are along the edges of the two sheets.

Remarkably, these damaged areas matched almost perfectly to the last restored original end leaf of the book-block proving that this sheet was originally placed at the back of the book and not at the beginning.

The Repairs

The conservation of the volume involved the removal of the leather strip supports. These supports were failing and becoming brittle due to the acidic nature of the tanned leather. The strips were mechanically removed from the sewing thread passages and replaced with new linen tapes so that the book did not have to be re-sewn.

The leather of the cover was reinforced and in-filled with dyed Japanese paper and wheat starch paste.

Japanese paper and wheat starch paste are used because of their strength and reversibility.

A new spine lining made of light cotton fabric was adhered to the spine of the book-block to further secure the sewing. The extensions of this spine lining with the frayed linen supports were then inserted between the leather and the boards and adhered to the boards to secure the book-block back with its cover.

Conclusions

It is hard to say why this page was tampered with. Possibly it was thought that by attaching this page to the front board it would become more difficult to steal. Sometimes conservation needs some forensic skills, but it always requires great attention to detail. Physical features when correctly interpreted can tell us a lot about the history of an item. It is extremely important when repairing items of historical value that conservators are careful not to inadvertently hide or remove features which may later prove to be significant.

This work, carried out a long time ago, is today still one of my most cherished projects. I am very pleased to be able to share it with you, especially during this year so significant in the history of the Great William Shakespeare.

Every year we conserve approximately 2,200 items, taking hours of skilled work, but there are many more items in need of repair. As the Library’s collection continues to grow and age, so do the number of items that need our attention.

In this post, book conservator Zoe Miller describes the work carried out to conserve Sloane Manuscript 1006, Astronomical Scheme after Henricus Khunrath.

This unusual and unique late 17th century manuscript came to conservation in a very poor condition. It was thought to have been produced by Dr Heinrich Khunrath (1560-1605), a physician, hermetic philosopher and alchemist who travelled Europe working as a court physician. He met John Dee, one of several alchemists who heavily influenced his famous work Amphitheatrum Sapientiae Aeternae [The Amphitheatre of Eternal Wisdom].

The binding, with its covering of sprinkled calf skin with green paper had broken, much of the original leather and paper covering had worn away and the spine and sewing were split in many places. It was foxed (a form of age-related chemical degradation of paper which causes reddish-brown spots) with ingrained surface dirt and many folds and stresses to the contents through inappropriate handling.

Much of the damage is a result of its physical uniqueness. The text block consists of heavy weight single folios sewn on cords, onto which are stitched 181 paper objects with hand drawn geometrical diagrams and deconstructions of an astronomical model.

These paper objects—often annotated in iron gall ink—have been carefully arranged on each folio and freely hang from the page as it is turned, posing a significant risk during handling and consultation.

Very little detail was known about the provenance of this volume, its creator, or the scholarly importance of the curious contents. This posed a problem. With all objects I am responsible for conserving, I aim to build a detailed conservation treatment proposal from an understanding of the cultural, historical and intellectual context of an object and its past use and ownership. This is to ensure that important historical evidence is preserved and that its scholarly value is not inadvertently diminished.

Working together with collection specialists we arranged to meet a previous reader of this book, a university professor whose expertise could help us make informed decisions for treatment. As the conservator, I was able to add to the body of knowledge of this item through my physical examination of the materials and processes used to construct the book and by contributing my understanding of patterns of deterioration and damage.

As a result of this interesting discussion it was decided to digitise the manuscript in order to preserve the exact state and positioning of the contents for scholarly study. This also will allow us to restrict access to the original in order to preserve it.

In preparation for digitisation, the manuscript was cleaned and dis-bound, removing broken threads and degraded binding materials which were causing further vulnerability.

Surface cleaning showing before and after cleaning

The astronomical objects were then stabilised using repair techniques which respected delicate inks and pigments to enable high quality images to be taken.

Following digitisation, the volume was returned to the Centre for Conservation to undergo further treatment. After recreating the original sewing structure the book boards were consolidated to prevent further loss of fragile materials and reattached to the text block.

Resewing the volume.

A flexible, low adhesive method was chosen to repair the spine using layers of Japanese tissue and wheat starch paste to recreate the original appearance of the binding as a tight-back (where the spine covering is adhered directly to the spine folds and sewing supports) while in reality creating a hollow-back, which serves to protect both the spine folds and the original spine labels which were adhered to the new covering leather.

Finally the delicate remnants of gold finishing from the degraded leather spine, which had been carefully removed before treatment, were encapsulated, to be stored with the volume for future consultation. Wherever possible we will aim to keep valuable evidence of a previous binding if it cannot be re-used.

Before and after conservation.

Treatment of this unique object has not only stabilised it physically for future generations but through digitisation we have been able to make its contents available to scholars within this niche area of study. Conservation has enabled and contributed to a growing body of knowledge on this manuscript.

Zoe Miller

Every item that comes into the Centre for Conservation receives this kind of care and attention, because to us every item is a treasure in its own way. It’s our high standards and level of expertise that means conserving items is a timely process and we will not compromise on the quality of the work that we do.

Your can play your part in preserving our heritage by making sure we have the resource to play ours, together we can make it last for generations to come.

The Torah is the Hebrew Bible. Torah mantles are sometimes used to cover the Torah scrolls and are constructed in a similar way to a skirt. The ‘skirt’ has a top with two ‘holes’ and these allow the wooden scroll handles to protrude.

Construction of a Torah mantle.

 

Before conservation the front of Torah mantle OMS/Or 13027 showed degraded silk - probably caused by light damage.

 

During conservation solvent activation of adhesive on conservation net was applied to the degraded silk using portable air extraction.

Post conservation the Torah mantle now shows stabilisation of the degraded silk. This is most evident in the centre front left and right, around the pleats, and around the holes for the wooden scroll handles.
