Back in the lab: archaeobotany from Amara West


Philippa Ryan, Scientist, British Museum

Archaeobotany is the study of ancient plant remains, and I joined the field team at Amara West in Sudan earlier this year to collect samples for archaeobotanical analysis. Charred plant materials were retrieved on-site from sediments through dry-sieving and flotation. These samples were subsequently brought back to the British Museum for further sorting and identification.

At the moment I am analysing the charred seeds and fruits with Caroline Cartwright, who is also analysing the wood charcoal. The macroscopic plant remains are analysed using both a stereo microscope and a SEM (scanning electron microscope). Charred remains found so far include cereal grains (wheat and barley) and crop-processing waste, fruits such as figs and a wide range of wild plants.

I am also processing sediment samples to extract phytoliths (microscopic plant remains), which are formed when soluble silica taken up in groundwater by plants is deposited within and between certain plant cells. These silicified cells are found within many different plant families such as grasses (which include cereals), sedges and palms.

Phytoliths are difficult to identify, but have the advantage of surviving in both charred and non-charred contexts, so we can learn about the presence and use of plants in areas where seeds and grains don’t survive.

At the moment, I am processing sediments to extract phytoliths, which includes the removal of carbonates, clays, organics, other remaining non-siliceous material through heavy liquid flotation, and finally mounting dried phytoliths onto slides. Phytoliths are then identified and counted using an optical (light) microscope.

Analysis of these different types of plant remains helps us learn about the past uses of plants at Amara West in day-to-day life, such as for food, fuel and animal fodder. I am also looking at the distributions of seeds and phytoliths across the site to examine locations of plant based activities such as food processing, as well as whether there are any differences in diet between poorer and richer households, or across the history of the site.

Plant remains can also help to provide information about the nearby vegetation, for instance the types of grasses, wetland plants and trees that grew near the ancient town.

This wonderful photo by @what_fran_saw captures the stunning Great Court #regram #repost
The two-acre space of the Great Court is enclosed by a spectacular glass roof made of 3,312 unique pieces!
Share your photos of the British Museum with us using #mybritishmuseum and tag @britishmuseum The roaring lions on the walls of King Nebuchadnezzar II’s palace represented the Babylonian king himself and were intended to astonish approaching visitors. Nebuchadnezzar commissioned major building projects in Babylon to glorify the capital of his empire. Glazed bricks in bright shades of blue, yellow and white were favoured for public monuments in order to emphasise both divine and royal power. These works displayed the might of the city and its king, who commanded unlimited resources.

#lion #art #history #BritishMuseum Lions have perhaps been adopted as a symbol more than any other animal. They are seen as proud, fierce and magnificent – characteristics that made kings and countries want to associate themselves with these charismatic big cats. As well as being the national symbol of England and Scotland, the lion is in many ways the symbol of the British Museum. Lions guard both entrances to the building. At the Montague Place entrance are the languid lions carved by Sir George Frampton, and on the glass doors of the Main entrance are the cat-like beasts designed by the sculptor Alfred Stevens in 1852.
This lion can be found on the wooden doorframe at the south entrance to the Museum, and its nose is polished smooth by the many visitors who rub it for luck on their way in. Share your photos using #mybritishmuseum and tagging @britishmuseum This colossal lion in the Great Court is one of the most photographed objects in the Museum. It weighs more than 6 tons and comes from a tomb in the ancient cemetery of Knidos, a coastal city now in south-west Turkey. The tomb stood on the edge of a cliff overlooking the approach to Knidos harbour. The building was 18 metres high and the lion was on top of its pyramid roof. The hollow eyes of the lion were probably originally inset with coloured glass, and the reflection of light may have been an aid to sailors navigating the notoriously difficult coast. It is carved from one piece of marble, brought across the Aegean Sea from Mt Pentelikon near the city of Athens. Opinions vary as to when it was built. One suggestion is that it commemorated a naval battle off Knidos in 394 BC.
We’ll be sharing more lovely lions this week! Share your photos using #mybritishmuseum and tagging @britishmuseum. Our next special exhibition will explore the remarkable story of Sicily. Discover an island with a cosmopolitan history and identity – a place where the unique mix of peoples gave rise to an extraordinary cultural flowering.
Norman Sicily was a centre of multiculturalism and its art reveals a unique mix of influences. The Norman kings invited Byzantine mosaicists from Constantinople to decorate their cathedrals and palaces. Spectacular golden mosaics can still be found in Roger II’s palace chapel and the cathedrals at Cefalù and Monreale. This mosaic, depicting the Virgin Mary, is all that remains of the extensive mosaics that once decorated Palermo Cathedral.

#Sicily #Italy #art #mosaic #exhibition #BritishMuseum Our #SicilyExhibition, announced today, will be the first in the UK to explore thousands of years of Sicily’s cosmopolitan history. The Greeks arrived in Sicily from 8th century BC, which led to a flourishing of art and culture.
This gold libation bowl, which dates from around 600 BC, was found in an ancient tomb at Sant’Angelo Muxaro in the 18th century. The bowl is decorated with six bulls. Anyone owning a bull would have had high status and commanded respect within the community. Although likely the work of local craftsmen, the bowl combines Greek and Phoenician designs. This blend of influences was typical of many objects made in Sicily between 800 and 600 BC due to contact with new settlers.
