Examination under the microscope (prior to repair) of the Egypt Exploration Society’s papyri.

In preparation for the Egypt: faith after the pharaohs exhibition five papyri, kindly loaned from the Egypt Exploration Society, came into the Paper Conservation studio. As papyrus conservator at the British Museum I have worked on a wide range of manuscripts held by our Department of Ancient Egypt and Sudan over the years. The collection includes many fine examples of papyri from ancient Egypt such as temple accounts from Abu Sir dating from approximately 2400 BC, some of the longest and beautifully illustrated funerary rolls from throughout Egypt’s long Pharaonic history, as well as literary texts and day to day legal documents. Working on such material has always been fascinating but I was particularly delighted to be able to work on these five papyri as they were excavated at Oxyrhynchus. The story of this excavation had fired my initial interest in papyrus as a paper conservation student many years ago.

The ancient town of Oxyrhynchus, meaning ‘city of the sharp nosed fish’, modern al-Bahnasa lying 120 miles south of Cairo, was excavated between 1896 and 1907 by papyrologists Bernard Grenfell and Arthur Hunt. This excavation began as part of a systematic exploration of the sites of Greco-Roman settlements and their discoveries were made in the sandy mounds on the outskirts of the town. The mounds turned out to be ‘drifts’ of rubbish tips which proceeded to yield approximately half a million fragments of papyri with ancient texts including early Christian literature. Grenfell and Hunt spent six seasons at Oxyrhynchus and their discoveries were by far the most exciting of the time in terms of quantity and range of the manuscripts found. Here was found several centuries worth of archives where official and private documents collectively provided a rare insight into the everyday life of this Roman town’s inhabitants during the 1st to 6th centuries AD. The papyri that came to the paper conservation studio included a rental agreement between two female monks leasing part of their home to a Jewish man (P.Oxy 3203) excavated in the first season, a small fragment containing the Greek Septuagint (P.Oxy 3522) and another depicting an informal drawing of Daniel in the lion’s den, both excavated in the fourth season. It is unknown during which season the last two papyri were found but they addressed matters relating to the Roman requirement for all citizens to sacrifice to the gods and include a Certificate of Sacrifice (P.Oxy 3929) and a letter from a Chrisitian man named Copres about a way to avoid the obligation (P.Oxy 2601).

The Cyperus papyrus L. plant. 

Undoubtedly helped by the dry climate of Egypt, papyrus has proved to be a very durable writing material with remarkable powers of preservation. Made from Cyperus papyrus L., a sedge plant about four metres high that grew plentifully along the banks of the Nile in antiquity, a sheet a papyrus was made from sections of the lower part of the stem where it was at its thickest. The outer rind is peeled off to reveal a spongy white inner pith which can be sliced longitudinally to make thin strips. These strips are laid side by side to form one layer before laying a second layer on top at right angles, then pressing and drying the whole. Individual sheets made in this way could then be joined to form a roll.

Two layers of strips are laid at right angles over each other. The two layers are then pressed together to form, when dry, a sheet of the writing material.

The five papyri for the exhibition were in need of minor repair and all except the small fragment of Daniel were in need of remounting between new sheets of glass. It was decided to exhibit Daniel in a passe-partout without glass to try and enhance viewing for the visitor. Generally papyri are so fragile that glass mounts are necessary for their protection but in this case, the fragment being small and in reasonable condition, an exception was made for the duration of the exhibition.

All the papyri were examined under magnification before opening the old glass mounts and starting any treatment. Once opened a bloom or ‘halo’ could be immediately seen on the old glass, in the case of P. Oxy 3203 it was very pronounced. This is a common feature with papyri enclosed in glass, particularly those found by excavating rubbish tips where they are found together with other material such as potsherds, ash, charcoal, rags, straw, and various kinds of kitchen waste. In this type of archaeological context papyri will absorb soluble salts. When later enclosed in glass, and even in conditions where relative humidity changes very little, the salts absorb small amounts of moisture from the surrounding air. As the air slowly dries out again these soluble salts migrate outwards and deposit themselves on the nearest surface which in this case is the glass. This can happen repeatedly over the years and a substantial ‘bloom’ can build up inside the mount making the papyrus quite hard to read. Scientific analysis has found the bloom to consist of mainly sodium chloride, common salt, and it can be wiped off the glass very easily. However the Oxyrhynchus papyri were all remounted in new glass for the exhibition.

Repairing fractured areas using small tabs applied with tweezers

Before remounting some conservation work was undertaken on the manuscripts. This involved laying back loose or twisted fibres and repairing along fractures. Repairs – in this case small pieces of Japanese paper, used for its strength and quality and toned to a sympathetic colour – are applied to the papyri with starch paste. The newly mounted papyri now take their place in the exhibition alongside the other fascinating objects that tell the story of faith after the pharaohs.

Egypt: faith after the pharaohs is at the British Museum until 7 February 2016.

One house we have been excavating (E13.8) is not only located against the four metre-thick northern wall of the town but also at the limit of previous excavations undertaken by the Egypt Exploration Society (EES). The EES excavated the temple, parts of the town and the cemeteries in 1938-9 and 1947–50.

Part of being an archaeologist in the twenty-first century includes rediscovering and reinterpreting the work of our predecessors in the field, when methods and aims were different from today. The excavators of the 1930s and 1940s focused on the temple, inscriptions and architectural plans. Occupation deposits received almost no attention, and of course many analytical methods now available were unheard of then.

We have just emptied 61 years of accumulated sand from one of the buildings excavated in 1949-50, immediately adjacent to our house E13.8. At the base of the excavation, we found a wall of a building they designated E.12.6.

In addition to confirming the accuracy of their plan, we can now explicitly link their architectural phases to ours, which means much of the town excavated in the 1930s and 40s can be fitted into the stages of urban development we have been able to reconstruct from the houses we are investigating.

The previous excavators never saw the eastern side of building E.12.6, and it is something we may find in the coming weeks…

Other aspects of the EES excavations have also come to light – including a fine matchbox found next to the residence of the Deputy of Kush, in a street partly excavated in the late 1940s. It has been registered as a find alongside the artefacts of the ancient inhabitants, as it all forms part of the site’s history.

Don’t forget to look up! ☝🏼 The triangular feature above the columns of the Museum’s main entrance is called a pediment. Originally it had a bright blue background and the statues were all painted white. 
The sculptures in the pediment show the development of ‘mankind’ in eight stages – a very old-fashioned idea now, but it was designed and built in the 1850s. The left side shows the creation of man as he emerges from a rock as an ignorant being. He meets the next character, the Angel of Enlightenment who is holding the Lamp of Knowledge. From the lamp, man learns basic skills such as cultivating land and taming animals.

The next step in the progress of civilisation is for man to expand his knowledge and understanding. The following eight figures represent the subjects he must learn to do this – architecture and sculpture, painting and science, geometry and drama, and music and poetry. The final human figure, on the right, represents ‘educated man’. Learn more about the Museum’s architecture and its fascinating history in our new blog – follow the link in our bio! We’d love to hear what you think. 258 years ago we opened our doors to the public for the first time! The British Museum is the world’s oldest national public museum, founded in 1753. It was created to be free to all ‘studious and curious persons’ and it’s still free today, but a few things have changed…

Did you know that the @natural_history_museum used to be part of the British Museum? The Museum’s founder Sir Hans Sloane had collected a vast number of natural history specimens, and these were part of the Museum’s collection for over a hundred years. In the 1880s, with space in Bloomsbury at a premium, it was agreed that these collections should move to a new site in South Kensington.

This photograph by Frederick York shows a mastodon skeleton on display here in Bloomsbury, before it moved to South Kensington in the 1880s.

Explore more of the Museum’s history on our new blog – follow the link in our bio and let us know what you think! The British Museum opened to the public #onthisday in 1759, the first national public museum in the world! 🎉

The Museum was founded on the death of Sir Hans Sloane, who bequeathed his collection of 71,000 objects to the nation. The British Museum Act gained royal assent in June 1753 (which makes us older than the USA!). The original collection featured 1,125 ‘things relating to the customs of ancient times’, 5,447 insects, a herbarium (a collection of dried plants), 23,000 coins and medals and 50,000 books, prints and manuscripts.

This photograph of the front of the Museum was taken in 1857 by Roger Fenton, the Museum’s first official photographer.

To mark this anniversary, the Museum is launching a blog where you can find all kinds of interesting articles – things you didn’t know about the Museum, curators’ insights, behind-the-scenes stories and more. Follow the link in our bio – we’d love to know what you think! In the early 1830s, following the success of ‘Thirty-six views of Mount Fuji’, #Hokusai worked to produce several follow-on print series. These featured waterfalls, bridges, and the flower series depicted in both large and small sizes. Hokusai probably composed this design without seeing the waterfall or referring to an existing image. He was free to use his imagination, and produced a strikingly idiosyncratic print that contrasts the marbled currents at the top with the perpendicular drop of the falls. Three travellers warm saké (rice wine) as they enjoy the view.
Our upcoming exhibition will explore Hokusai’s iconic work, and allow you to learn more about his enigmatic life. The exhibition opens on 25 May 2017 – learn more and buy tickets by following the link in our bio.
The exhibition is supported by Mitsubishi Corporation.
Katsushika Hokusai (1760–1849), Amida waterfall, deep beyond the Kiso highway. Colour woodblock, 1833. The Tōyō Bunko, Tokyo. On display 7 July – 13 August 2017.
#Hokusai #waterfall #Japan #JapaneseArt #print #nature #landscape Our #Hokusai exhibition will feature stunning works – from dramatic landscapes to exquisite depictions of birds and flowers, like this bullfinch. He worked tirelessly to capture what he called the ‘form of things’ and to show how they relate to one another. Hokusai has depicted a male bullfinch, distinguished by its pink marking from cheek to throat. The bird and flower stand out in relief against the background of deep Prussian blue (a colour that had only recently been invented, used to great effect by Hokusai).
The exhibition ‘Hokusai: beyond the Great Wave’ will open on 25 May 2017. With many of the works coming especially from Japan, it’s a rare opportunity to see the artist’s work on display in the UK. Follow the link in our bio for more information and to book tickets! 
Join us for a #FacebookLive broadcast later today at 17.30 GMT and ask your questions to our Hokusai curator Tim Clark! 
Katsushika Hokusai (1760–1849), Weeping cherry and bullfinch. Colour woodblock, 1834. On display 7 July – 13 August 2017.
#Hokusai #Japan #JapaneseArt #print #bird #nature #cherry 🌊 Hokusai’s most famous print, known as ‘The Great Wave’, will be one of the highlight works in our upcoming #Hokusai exhibition (25 May – 13 August) . It was created when the artist was in his early seventies and was one of a series – ‘Thirty-six Views of Mount Fuji’ – which celebrated the sacred mountain with views from different seasons and locations. Hokusai increasingly identified with Mount Fuji as a source of long life, even immortality.

The exhibition ‘Hokusai: beyond the Great Wave’ will feature sublime prints and paintings by one of Japan’s greatest artists. Follow the link in our bio for more information and to book tickets!
