History of Papyrus Conservation


Conservator Dr. h.c. Hugo Ibscher, working in Germany, 1933

Originally papyrus manuscripts were preserved and cared for by the scholar who discovered the pieces. Fragments were often taped or otherwise manipulated at the actual archaeological site. We have examples of postage stamps and all kinds of odd materials used to piece together fragments. The most famous of the early papyrus conservators is Dr. h. c. Hugo Ibscher (1874-1943), a trained bookbinder, who worked on the restoration and mounting of papyrus manuscripts at the State Museum in Berlin, starting in 1891. For over forty years, he worked on papyrus manuscripts at the Egyptian Museum in Berlin and all over the world, including Turin, London, Oxford, Brussels, Paris, Prague, Copenhagen, Cairo, Rome, and many others. He’s considered the founder of papyrus conservation and his son Dr. Rolf Ibscher (1906-1967) followed in his footsteps, hiding important pieces during the war. Apart from the work in Berlin, a lot of “conservation” occurred first at the British Museum where papyrus manuscripts were then divided among members of a collecting consortium. The conservators who were in charge of papyrus generally had book and paper backgrounds, and this remains the case today. There are very few places that can afford to have a dedicated papyrus conservator.

At the University of Michigan, which holds the largest collection of papyrus in North America, conservation activities began in the late 1980s, when Professor Ludwig Koenen raised awareness of the need for conservation of the papyrus collection. He was a professor in the classics department for papyrology who taught from 1975 until 2001, when he retired. He remains active in the papyrological community today.

Conservator Leyla Lau-Lamb works with papyrologists Prof. Konen and the late Prof. Gagos at the University of Michigan

During Prof. Koenen’s years, Julia Miller was working as a conservator at the University of Michigan, and she spearheaded the research and development of protocol for the treatment and housing of papyrus manuscripts. She later retired from her conservation duties, and is now a highly regarded scholar in the history of bookbinding and lecturer on the subject of early codices, especially the Nag Hammadi codices, which are early bound structures with papyrus textblocks and cover boards. She has constructed collections of incredible models that can be studied in the University of Michigan's Special Collections Research Center.

In the early 1990s, the book and paper conservator Leyla Lau-Lamb took over papyrus conservation duties and was heavily involved in the Advanced Papyrological Information System (APIS), a “virtual library” that provides online access to Michigan's papyrological collection. Users are able to view digital images and detailed catalog records containing information on papyrus characteristics and corrections to published papyri. This digitization project involved a consortium of universities, including Columbia, Duke, Yale, and Michigan. Leyla was assigned the task of treating, rehousing, and inspecting 1,000s of fragments with the papyrologists working on the huge APIS project. Over two decades, Leyla developed and perfected treatment methods and standards, which she shared with people worldwide, and put Michigan on the map for being a source of knowledge for papyrus conservation. She also wrote the APIS conservation guidelines, which are highly referenced to this day. While the APIS project is no longer active, Michigan continues to digitize its collection, adding records to the database. The images and metadata from this project are still maintained by the universities in the consortium, and can be accessed through Papyri.info.

Conservator Bridget Leach working at the British Museum

There are several other highly influential papyrus conservators who have dedicated their careers to this specialty. Their articles and research have shaped everything we understand and practice currently. Bridget Leach is a retired papyrus conservator from the British Museum, where she worked from 1990. Her particular research interest focused on pigments used on illustrated papyri, which the British Museum is fortunate to have. She has written some very valuable resources, which are listed in the bibliography below.

Conservator Myriam Krutzsch removes tape from a fragment during a visit to U-M

Another highly influential papyrus conservator is Myriam Krutzsch, who has worked at the Egyptian Museum in Berlin since 1975. She was trained by Otto Werner Luke, who was trained by Dr. Rolf Ibscher. Myriam solely works on papyrus and has written many valuable resources, most of which are in German, which is one of the major languages in the papyrological discipline. Her particular research interest focuses on the complex folding techniques of ancient Egyptian texts and papyrus manufacture. Leyla studied with her early in her career, therefore much of what is established at the University of Michigan is informed by Myriam's procedures. She generously takes on students and conservators from all over the world for periods of study in Berlin, travels to other institutions for consultation and teaching, is an active consultant at archaeological sites in Egypt, and continues to publish and give talks at conferences to continuously add to and update our knowledge on papyrus manufacture and care.

Material and Structure


Creating a sheet of papyrus

Most of our knowledge about the use of papyrus for a writing surface comes from Pliny the Elder, who described the papyrus plant and its use in his Natural History from AD 70. He stated, “The nature of papyrus too is to be recounted, for on its use as rolls human civilization depends, at the most for its life, and certainly for its memory.”

Papyrus that was used for a writing material is generally identified as Cyperus papyrus, as tall flowering freshwater reed, which grows in Africa along the water’s edge, in particular the Nile River. The writing material is made from the core of the stem, and the particular variety used in the ancient world does not vary greatly from one sub-species to another, therefore it has not been specifically identified. Differences are observed depending on where the sub-species was growing.

The plant was used widely in everyday life, from sandal-making and basketry, to boats, sails, rope, and was even a food source. There are no ancient Egyptian representations or texts on the production of papyrus sheets and rolls, and no specific papyrus workshop has been uncovered.

The triangular stem of the papyrus would be cut or peeled in long strips. There has been longstanding speculation whether the core was cut into several strips or was peeled into a single thin layer, but it was likely a combination, and techniques likely varied throughout the years.

Structure of a papyrus sheet

After cutting and peeling, the papyrus was laid in two layers, one horizontal and one vertical, to form a single rectangular sheet, with no gaps between the strips. The sheet could be rolled easier if the vertical strips were on the outside, therefore the vertical side is referred to as the verso. The majority of writing was completed on the horizontal, recto, side.

No adhesive was used to join the layers. When the wet strips were placed together horizontally and vertically, it is speculated that they were pressed or hammered together, leading to the the physical bonding of the cell tissue of both layers. In order to form a roll, the edges of the sheets were adhered together with a starch paste, generally right over left on the recto, which does vary depending on the region and time period. There are also examples of fringes of horizontal strips used for joins, thus leading to a smoother three layers overlapping rather than four. Examples show anywhere from 7 sheets in length (Middle Kingdom) to 20 sheets in length (Roman Period, Early Islamic Period).
