Elizabeth Galvin, curator, British Museum

I am currently looking at 25,000 objects from the Museum’s collection on my desk. These fantastic works detail an important part of human history in Africa and range from beautiful bas-relief cattle to stunning painted representations of women dancing. Yet these items are not from the Museum’s storage facilities: they are saved on a hard drive, as part of the African rock art image project. The project team is cataloguing and uploading these 25,000 digital images of rock art from throughout the continent, so each one of them is being registered into the Museum’s collection as an object in its own right and made available through the Collection Online.

While digital collections are a relatively new area for the museum industry, they are showing new and exciting ways museum visitors can engage with the collections, as well as adding to our scholarship. As part of this project, the digital photographs have allowed the Museum to use new technologies to study, preserve, and enhance the rock art, while leaving it in situ in Africa.

For example, this digital photograph shows a piece of rock art that has been chipped and faded through natural erosion. With the naked eye, we can see some remnants of a red-brown pigment. Maybe this was the legs of a quadruped or perhaps two abstract human figures. Most of the rock art in this area is thousands of years old, so knowing exactly what it looked like before it was eroded used to be impossible without extensive tests that could have easily destroyed the original work.

Now, however, using photo manipulation software, we can run the photograph through a process that enhances the pigments. By focusing on different sets of colours, we can see the layers that were previously hidden to the naked eye. In this one, we can see that the legs belong to an elephant, complete with large ears, a tail and trunk.

Run the same image through another enhancement, and we can see many more human figures that were previously invisible. The elephant is still somewhat visible in the background, highlighted in pink. But the fantastic hunters to the top right of the photo would never have been identifiable in the original rock art. Now we can see them with their bows and arrows in an active hunting scene. ‘Swimming’ figures are now highlighted in the centre of the photograph. At the right of the image, we are also able to see a section of a giraffe, depicted with a spotted coat.

By using new technologies with the digital collections, we are not only able to enhance our study of the rock art, but also to build a database to ensure open access to our work. We are regularly using social media, blogs (like this one), and thematic articles on the main Museum website, both to increase access to these amazing works of rock art, and to facilitate discussion with our online visitors across the world. While the Museum’s physical collections will always be at the core of its work, digital collections are letting us see objects in a new light. After all, a 21st-century museum requires 21st-century collecting.

On Monday 6 October 2014 at 1.30pm, Elizabeth Galvin will be giving a free public lecture on African Rock Art and Photography with renowned photographer David Coulson (from the Trust for African Rock Art),  in the BP lecture Theatre at the British Museum in London. Tickets are free, but booking is recommended via the British Museum website to ensure a place.

In a valley of Libya’s Acacus Mountains, in the middle of the Sahara Desert, an elephant steps out from under an overhang of red rock. Giraffes, cows, camels, people, a horse and a hare are there too. They may seem out of place in such a harsh environment, but they are not lost: they have been there for thousands of years, painted and engraved on the rock shelter wall.

The African rock art image project team here at the British Museum is currently cataloguing photographs of rock paintings and engravings from Libya, Morocco and Algeria to add to the British Museum’s Collection database. Already, over 4,000 records from these countries, as well as from Egypt and Sudan, can be seen online. You can find out why we’re cataloguing almost 25,000 images from the archives of the Trust for African Rock Art by reading our previous blog post.

The photographs depict rock art from throughout the continent, created over millennia and encompassing diverse subjects and styles, sometimes represented side by side on the same rock surface. This Libyan site, in Wadi Raharmellen, is just such an example, with its variety of depictions and inscriptions made by different hands. So who created these particular images, and how old are they?

The earliest rock art in the Acacus is thought to consist of engravings of wild animals, such as the elephant and the giraffes. Archaeological evidence dates early hunter-gatherers here from around 9000 BC, during the Sahara’s last wet period, when the area was less arid and supported such large animals, which now only live much further south.

It is sometimes possible to estimate the earliest date at which rock art could have been made based on the first known introductions of the domestic animals they depict to this part of the world: cattle (from about 7,000 years ago), horses (from about 3,000 years ago) and camels (from about 2,000 years ago).

In this rock shelter, the bright white figure of a camel is painted over an engraved elephant. To the right of this, the necks of two engraved giraffes have inscriptions all over them: the writing is Libyan-Berber (an ancestor of modern Tifinagh script), which is not fully understood. The presence of Arabic, carved further along the rock face, seems to bring the story of the use of this great communal canvas into recent times.

The dating of rock art is notoriously difficult. Although paintings here appear to be younger than the oldest engravings, the tradition of engraving endured. Step back a few paces from the small elephant, and it is dwarfed by another image to the right: the outline of a cow, not painted like the red one above, but incised deeply into the rock.

Further along is an ostrich carved with equal conviction. This might be contemporaneous with the cow, as there was a period of overlap when cattle herders and animals such as ostriches and gazelle coexisted. Recent archaeological evidence from this area also seems to indicate that people were corralling, if not domesticating, wild sheep here before cattle arrived. Perhaps nowhere is the intermingling of wild and domestic animals better illustrated than in the centre of the panel, where the engraved hoof-prints of an antelope and a cow are printed into the rock face, side by side.

Ostriches are the only wild animals painted on this panel: three small, white ostrich figures are shown one behind the other, facing left, below the more recently painted series of camels, with their stylised drivers and raised arms. Both of these processions are dwarfed by the engraved human figure to their right, striding purposefully towards them, whose delicately lifelike engraved outline implies a different time and artistic tradition from the creator of the daubed, faceless camel-drivers.

These human figures, depicted among the animals, serve as a reminder of the different creators of this art, who came from different time periods and cultures, and for whom the images must have had different personal meanings and significances. This, in turn, cautions researchers of the difficulty in ascribing overarching interpretations and motivations to rock art, since it is not a genre with specific traditions, but rather the use of a variety of possible techniques to mark a durable and abundant natural canvas: rock. Some images may have been made for religious purposes, some with the aim of specific communication; still others may be products of experimentation, or even of boredom.

The project covers rock art spanning thousands of years, over an entire continent. Such breadth and variety throws up many challenges and questions, as well as imagery and evidence for various practices and material cultures. As we progress down through Africa, we’ll be updating our project pages with articles and discussions on these themes, as well as updates and features on individual sites and images. We hope you will join us on our digital journey as we explore this rich artistic heritage.

London, a world city in 20 objects: Ilkurlka by Simon Hogan

Ilkurlka by Simon HoganPolly Bence, British Museum

This painting is one of almost 6,000 objects from Australia and the Torres Strait Islands in the British Museum. This is a growing collection; the Museum continues to acquire contemporary Indigenous Australian objects, including contemporary art works.

Ilkurlka by Simon Hogan

Ilkurlka by Simon Hogan

Ilkurlka was painted by Simon Hogan, a senior custodian of Linka, the place where he was born and raised in Western Australia, known as Spinifex country. The Spinifex people or Pila Nguru live in the Great Victoria Desert of Western Australia, adjoining the border with South Australia.

Hogan’s paintings tell stories from his land, depicting specific places within Spinifex country. As is often characteristic of this genre, the painting collapses time: it shows several successive events on top of each other. The large U-shape in the painting is a rockhole with water in it known as Ilkurlka and the trees are mulga trees (wanarii). When describing this painting Hogan explained: ‘those trees belong to that place’.

The painting tells the story of a man who was camping at this rockhole. He woke up and travelled to another place where there was a very powerful watersnake that he was trying to capture.

In describing the painting the artist explained that in it the man is trying to eat the snake and at the same time he has eaten it – he is both a man and a snake. The oval shape depicts the man lying down, feeling sick having eaten the snake – but the man now has a great deal of power.

During the atomic tests at Maralinga in western South Australia during the mid-1950s, the Spinifex people were driven from their homelands. Many found themselves dispersed and others were forcibly relocated to mission stations hundreds of miles away. In the 1980s people returned to their land to find that specific settlement areas had been designated for them and some areas had been selected for mining.

The 1990s saw an arduous and lengthy period of negotiations over land rights and native title claims, and it was during this period that the Spinifex Arts Project was developed to help the group document and illustrate their Native Title claims. This decade of discussion culminated in 2000 with ground-breaking legislation and a new understanding: Spinifex people were finally recognised as the traditional owners of 55,000 square kilometres of land in Western Australia. Spinifex artists produce work to demonstrate and share their complex history and traditions.

The British Museum is working towards a major Indigenous Australian exhibition which will open in 2015, which will include Spinifex paintings.

London, a world city in 20 objects: the Crucifixion of Christ

The Crucifixion of ChristChristopher Spring, British Museum

The modern state of Ethiopia was created from an ancient kingdom founded over two millennia ago. Originally extending across the Red Sea into what is now Yemen, the Aksumite Empire of Ethiopia became Christian in the fourth century. It is associated with the biblical mythologies of Solomon and of Sheba, and in the medieval west with the Christian Patriarch Prester John. Ethiopia is mentioned several times in the Bible, and its church is one of the oldest in the world. Although Ethiopia, then as now, is a country of many faiths and cultures, including Christians, Muslims and Jews.

Ethiopian Christian churches thrive among diaspora communities, with many congregations based in London. This remarkable painting tells multiple stories, with layered meanings, about Christianity and empire.

The Crucifixion of Christ

The Crucifixion of Christ

It was created in the mid-nineteenth century for the Church of the Saviour of the World at Adwa in northern Ethiopia. Its central image of the Crucifixion of Christ was painted to inspire devotion among Ethiopian Christians. There is a convention in Ethiopian religious painting for the unbelievers or evil-doers to be painted in profile and for the righteous to be painted full face – therefore the two thieves with whom Christ was crucified are depicted only in profile. At the foot of the cross Christ’s blood flows into the mouth of the skull of Adam signifying humanity’s redemption through the blood of the redeemer.

The smaller scenes around the edge of the painting celebrate Bishop Selama, the Abune (Patriarch) of the Ethiopian Orthodox Church from 1841-1867. One scene shows the arrival of the Abune in Gandabta in 1841; Bishop Selama is shown riding on a donkey being greeted by jubilant crowds.

Church paintings at this time were an important means of communication and observers would have been able to identify the recent events depicted. For example, the third scene to the left shows Bishop Selama, wearing a red, hooded cape, anointing Emperor Tewodros II of Ethiopia at his coronation in 1855. Tewodros had an ambitious plan to unite and modernise the country, and is still regarded as a hero by many Ethiopians.

These illustrations of Bishop Selama’s life provide an insight into the complex relationship between Church and state in Ethiopia at the time, depicting a struggle for power. The coronation of Emperor Tewodros by Abune Selama reflects on their initial alliance and the Emperor’s need for the church’s support in unifying Ethiopia politically. However, it was an alliance which eventually collapsed largely because of Emperor Tewodros’ almost unstoppable desire for modernisation and the control of ecclesiastical power.

This was first published in the London Evening Standard in January 2013.

Dutch artist Aelbert Cuyp was born #onthisday in 1620. He seemed to be very fond of cows! The Sydney Opera House opened #onthisday in 1973.

Designed by the Danish architect Jørn Utzon, the Sydney Opera House provoked fierce public controversy in the 1960s as much over the escalating cost of its construction as the innovative brilliance of its domed sail-like halls. Now recognised the world over as a magnificent architectural icon jutting into Sydney Harbour, the Sydney Opera House finally opened in 1973. 
In this Christmas card for 1972 Eric Thake (1904–1982) cheekily anticipates the long awaited opening with his domestic version of the grand architectural statement. Crockery stacked in a drying rack forms the shape of the Sydney Opera House, with water from the kitchen sink adjacent. The small housefly resting on one of the stacked plates adds an unmistakably Australian touch.

#history #architecture #stpauls #London #art Room 4, Egyptian sculpture, is the next gallery in our #MuseumOfTheFuture series. The objects in this gallery range in date from 2600 BC to the 2nd century AD. Large-scale sculpture was an important feature of the great temples and tombs of ancient Egypt and was believed to be imbued with powerful spiritual qualities. Sculptures on display in Room 4 include stylised depictions of kings, deities and symbolic objects ranging from the time of the Old Kingdom to the middle of the Roman Period. There are also architectural pieces from temples and tombs.
An imposing stone bust of the great pharaoh Ramesses II presides over the room, while the world-famous Rosetta Stone (in the foreground of this pic), with its inscribed scripts, demonstrates how Egypt’s ancient form of pictographic writing was deciphered for the first time.
#museum #art #sculpture #history #ancientegypt #egypt #hieroglyphs Next in our #MuseumOfTheFuture series looking at all the galleries in the British Museum, it's Room 3. Since 2005 this room has housed a series of temporary displays – The Asahi Shimbun Displays. Usually focused on one object (although sometimes featuring several), it provides a space in which to experiment with display and interpretation. Displays have featured everything from ancient African hand tools to contemporary art, from Old Masters to manga. The current display (pictured) features an enormous print by Albrecht Dürer.
#museum #art #history Continuing our #MuseumOfTheFuture series showing all the gallery spaces, here's Room 2, Collecting the world.
The Museum was founded in 1753 and opened its doors to visitors in 1759. Room 2 celebrates some of the collectors who have shaped the Museum over four centuries, as well as individuals and organisations who continue to shape its future – from Charles Townley to Grayson Perry.
