Conserving the pottery, terracotta and tablets from Ur

Duygu Camurcuoglu, conservator, Ur Project, British Museum

My job is to assess the condition of the objects from Ur being studied as part of the Ur digitisation project, conserve them if necessary, and guide the project team on handling and safe storage of the objects before/during photography and further digitisation work. I joined the project in August 2013 to lead the conservation and my first responsibility was to assess and conserve the terracotta objects and the clay tablets with ancient cuneiform inscriptions on study loan from Iraq.

There are over a thousand terracotta objects from Ur in the British Museum’s collection, primarily reliefs, figurines and models. Although some are skilfully modelled, the majority are rather crude and mass-produced in moulds. My initial task was to assess each one, selecting those that needed treatment and completing the work before they could be handled and photographed. In the image above, you can see me assessing the condition of one of the important objects from Ur, the fired clay mask of Humbaba, a fearsome monster slain by Gilgamesh in Mesopotamian literature. During the process, colleagues from ceramics and glass conservation joined me to complete the assessment work on the objects, while I undertook the actual conservation treatments.

Following the terracotta objects, I assessed the condition of the pottery from Ur. This large collection comprises over a thousand ceramic vessels in various sizes, shapes, colours and fabrics. This was a huge challenge! Every day, my colleague Gareth Brereton and I went to one of British Museum’s storage areas where the pottery from Ur is housed. We set up a small working area in this room for object assessments, photography and registration. There were a large number of cupboards to go through, so Gareth and I worked almost every morning together, assessing the condition of each pot so that Gareth could handle, photograph and register them. We had plenty of exercise going up and down the ladder each morning as some of the objects were stored very high up in the shelves.

Most terracotta objects and ceramic vessels from Ur are in good condition. They sometimes require conservation work, since they have unstable fragments, flakes or cracks on their surfaces. This is very normal due to the age of the objects, most are which are about 4,000 years old. It is crucial that the necessary treatments are undertaken. When unstable objects are not treated using proper conservation techniques and materials, further problems may occur during storage and handling, such as loss of surfaces and decoration, cracks, breakage of fragments that can make it difficult to study and learn more from the objects.

I identify any cracks and/or unstable flakes on the surface of the vessels before stabilising them using conservation grade materials. I often use a fine brush or a micropipette for this work. Once the treatment is completed, I enter all my treatment records onto the British Museum’s curatorial database, Merlin, so that the information is accessible across the Museum and the world via the collection online.

I have also been assessing and undertaking conservation on the cuneiform tablets from Ur. It is particularly important to prevent the loss of surfaces from tablets, because that would mean loss of the text.

Apart from undertaking remedial ‘hands on’ work with objects, I am also responsible from supporting the Ur team when they have any questions about handling the objects safely, as some are very fragile. I also monitor the environmental conditions in the Ur project lab and storage cupboards, using digital sensors which we place in different areas. This is important because fluctuating temperature and relative humidity can severely damage archaeological objects. For example, soluble salts in the ceramic and clay fabrics can react very quickly with the fluctuating conditions, resulting in delamination and loss of object surfaces, which can contain elaborate decorations, pigments and reliefs.

When I have completed the conservation work on the pottery and the cuneiform tablets, I will move on to the conservation of other types of objects and materials from Ur, in order to prepare them for digitisation and further study. I am looking forward to the challenge!

I am responsible for managing the digitisation of objects and archives for the Ur Project, a dynamic new collaboration between the British Museum and Penn Museum made possible with the lead support of the Leon Levy Foundation. The project takes the successful cooperation of the two organisations of the 1920s and 1930s at Ur into the 21st century, digitally reunifying the remarkable finds from that site in a state-of-the-art website. We are photographing and documenting all the finds from Ur in our collections, from small pieces of broken pots to ancient cuneiform texts and exquisite gold jewellery. We are also digitising the original excavation photographs, archives, plans and other documents. Our resource will bring together these varied sources of information for the first time and make them available in an online database that will preserve the complete finds and records in digital formats for posterity.

Ur was an important city throughout Mesopotamian history. The excavations, led by Sir Leonard Woolley and jointly sponsored by the British Museum and the Penn Museum, uncovered its famous ziggurat complex, areas of densely packed private houses, and the spectacular Royal Graves with rich inventories of gold and evidence of human sacrifice. These unique finds provide crucial information about third-millennium society, as well as the warfare, music, food, drink, and customs of the period. We can also learn much about the people that lived and died in this city through the study of the cuneiform tablets excavated at the site. There are about 10,000 of these ancient texts from Ur in the partner museums’ collections.

By 1922–34 Woolley had developed his methods with an increased emphasis on recording. Thus, the vast scale of the finds he recovered – numbering into the tens of thousands – are contextualised by an abundance of documentation. The British Museum houses the core part of this documentation, such as the original glass-plate negative photographs, and the excavation diaries. We are digitising, indexing, and cross-referencing these indispensable resources.

The most exiting aspect of the project is the rare opportunity it provides to reunify dispersed information. Not only will the collections from the three museums (the British Museum, Penn Museum and the Iraq Museum) be integrated, but also the different categories of object brought together in one virtual space, and, crucially, barriers between object data and archives will be broken down.

Our website will present for the first time an authoritative set of high resolution images of the entirety of the finds, integrated with all field notes, catalogue records, photos, reports, maps, letters and publications. Importantly, data are recorded in a format that allows them to be fully indexable and extractable, enabling people to create their own datasets and make comparisons with their own research. This approach will also allow us to re-establish lost object identifications and crucial findspot information. We will relate internal references between notes, letters, publications and catalogues, connect artefacts to their findspots on maps, and link wherever possible to other resources with the goal of enabling researchers to analyse the site in exciting new ways. All data are thoroughly cross-referenced, facilitating the study of artefacts all the way from excavation context to current display.

Activity is currently underway at the British Museum and at Penn Museum. We hope soon to be joined by our colleagues at the Iraq Museum. Our work feeds into the shared project website, as well as each museum’s own collection database. Our web resource will eliminate traditional barriers between institutions, enabling people to focus on the material from Ur as a single corpus, disregarding the objects’ current locations. We hope that our approach will inspire the digitisation of other similarly dispersed collections.

The project staff bring expertise in archives, photography, programming, conservation, Assyriology and archaeology. This range of skills reflects the diversity of information being collated, and indicates the great potential for research our resource provides. I look forward to bringing you future updates about the project as it progresses.

Concluding our short series of gold objects from the Museum’s collection is this group of items found in the Fishpool hoard. The hoard was buried in Nottinghamshire sometime during the War of the Roses (1455–1485), and contains some outstanding pieces of jewellery. 1,237 objects were found in this hoard in total. At the time it was deposited, its value would have been around £400, which is around £300,000 in today’s money! The variety of this collection of objects includes brilliant examples of fine craftsmanship. The turquoise ring in the centre was highly valued as it was believed that turquoise would protect the wearer from poisoning, drowning or falling off a horse.
#hoard #gold #jewellery #turquoise #treasure Continuing our exploration of the golden objects in the Museum, this amazing inlaid plaque is from 15th-century China. Lined with semi-precious stones, this piece would have formed part of a pair sewn into a robe. We can tell this belonged to an emperor of the Ming dynasty because only he would have been allowed to use items decorated with five-clawed dragons.
#Ming #gold #jewellery #China #BritishMuseum Our next trio of objects shows off some of the shimmering gold in the Museum’s collection. This stunning piece of jewellery comes from Egypt and was made around 600 BC. It was worn across the chest – this type of accessory is known as a ‘pectoral’. Popular throughout ancient Egypt, pectorals have been found from as early as 2600 BC. This example is made from gold and is inlaid with glass, showcasing the incredible level of craftsmanship in Egypt at the time, and asserting the status of the wearer. Falcons were important symbols in ancient Egypt – the god Horus took the form of a falcon.
#AncientEgypt #gold #jewellery #BritishMuseum In 1991, BMW invited South African artist Esther Mahlangu to make a work of art in their Art Car project to mark the end of apartheid. Her work, with its brightly coloured geometric shapes, draws on the traditional house-painting designs of Ndebele people in South Africa. Under apartheid the Ndebele were forced to live in ethnically defined rural reserves – their designs are an expression of cultural identity, and can be read as a form of protest against racial segregation and marginalisation.

#SouthAfrica #history #art #design Mapungubwe was the capital of the first kingdom in southern Africa from AD 1220 to 1290. This gold rhinoceros, alongside four other gold sculptures, was discovered in three royal graves there. They are among the most significant sculptures in Africa today. They depict animals of high status – an ox, a wild cat, and a rhinoceros – and also objects associated with power – a sceptre and a bowl or crown. These treasures were discovered alongside hundreds of gold objects, including bracelets and beads. Gold was mined in the regions around Mapungubwe for trade with the coast, as part of an international trade network stretching as far as China, becoming a status symbol for the kingdom’s rulers.

On loan from the University of Pretoria @upmuseums, these gold treasures will be a highlight of our #SouthAfricanArt exhibition, opening 27 October 2016. Find out more about the exhibition by following the link in our bio.
#SouthAfrica #rhino #art #history Our special exhibition this autumn will explore the fascinating history of South Africa through art, telling a story that stretches back 100,000 years.

Rock art is one of South Africa’s oldest artistic traditions. It was first made by the ancestors of San|Bushmen and Khoekhoen, South Africa’s first peoples, at least 30,000 years ago.

This rock painting will feature in the exhibition. It depicts San|Bushmen running between eland, a type of antelope that is spiritually important. Hunter-gatherer rock paintings such as this are understood to relate to a ritual practice named ‘the great healing’ or ‘trance dance’, which continues today in the Kalahari outside of South Africa. 
The paintings address the relationship between healers, or shamans, and the worlds of the living and the dead. In the painting some eland are bleeding from the nose and frothing at the mouth. Eland do this when they are close to death, and shamans show similar symptoms when they are metaphorically ‘dying’ and entering the world of the dead during the great trance dance.
