The Beau Street Hoard: the end of the excavation

Beau Street Hoard excavationJulia Tubman, conservator, British Museum

My last blog post recounted the excavation of bags 5 and 6 of the Beau Street hoard, which were the two smallest bags on the edge of the large hoard. In the months since, the deconstruction of the hoard has advanced considerably: as the excavation progressed I naturally became faster and more confident in removing the coins, and am pleased to announce the end of this stage of the project. The hoard was well organised, with the coins carefully sorted into bags according to denomination and level of debasement; specialists here at the British Museum now have a fascinating mystery to interpret.

In total eight bags were found in the hoard, which is two more than originally identified in the x-ray. Squeezed between the larger ‘bag 2’ and the centre of the hoard were two tiny bags, the coins of which are very similar to those contained within bag 2 – small radiate coins minted by Gallienus, Claudius Gothicus and Tetricus I.

Luckily, at the end of the excavation I was able to lift the large, central moneybag (known as bag ‘4’), whole, as I had removed all of the bags of coins surrounding it. The excellent preservation of this moneybag, which weighs nearly 11 kilograms, presents us with a very exciting opportunity. Already a laser scan of the bag has been undertaken to produce a rotating three-dimensional image, and a second scan will be taken before the end of the year which will be used to produce a facsimile to go on display in Bath. These scans provide us with a lasting document of the moneybag, which will now be de-constructed and the coins cleaned.

The block was x-rayed before the excavation of the moneybags, and so the base holding the coins had to be x-rayed after the removal of the last bag, to check that there were no ‘surprise’ bags beneath those already excavated. The x-ray showed only a few coins on the periphery of the base, and so we can move towards giving a final count for the number of coins in the hoard as a whole: at the moment it looks to be around half of the original estimate of 30,000.

Now the excavation is complete, I will be fully focused on getting all of the coins cleaned so that they can be identified by numismatists, who will begin to compile an ‘Emperor count’.

We knew at the beginning of the project that this would be a short excavation, and the perfect opportunity to experiment with time-lapse photography. Before I began the excavation, a camera was positioned on a workbench above the hoard, and programmed to take a photograph of the stationary block every 10 minutes. This short video neatly captures the deconstruction of the hoard, and makes for a fantastic record of the excavation.

On Friday 30 November, Stephen Clews from the Roman Baths, British Museum curators Richard Abdy and Eleanor Ghey, and I will be discussing the story of the Beau Street Hoard so far in a lecture at the British Museum.

    How exiting this story has been, and so historical, I would have loved being there at the excavation of the these bags!

  5. Does anyone else REALLY want the job of separating them and cleaning them up. That looks like such a fun find. Great job maintaining the integrity of the hoard. Keep us updated.

    A fascinating post from Julia Tubman, conservator from the British Museum, literally unearthing more history. Will be great to see the next stage of their findings as the coins are cleaned and more about the hoard is understood.

    Part of the hoard is now on temporary display in the Citi Money Gallery at the British Museum. Watch this space for a blog update coming soon.

We’re sharing our favourite photos taken by visitors – use #myBritishMuseum if you’d like to feature! Here’s a brilliant shot by @j.ziolkowski that really captures the cool tones of the Great Court. We love the collision of lines in this photo – the hard edges of the original 1823 building set against the curvature of the later Reading Room and tessellation of the glass roof. 
Get snapping if you’d like to feature in our next #regram. 
#BritishMuseum #architecture #perspective #GreatCourt This Degas print is an example of the subject matter and technique the artist moved towards in the early 1890s. During this time, Degas produced sketchy prints showing female figures post-bathing. In this print we can see that the ink has been reworked during the printing process – the hair and shoulders show evidence of additional brushstrokes. The backgrounds of these works are much more sketchy and blurred than works he produced earlier in his career, perhaps showing his increased interest in figures.
#Degas #print #portrait The intense gaze of this young woman was originally intended to appear in the background of a horse racing scene by Degas, but the painting was never completed. This type of challenging composition is typical of the French artist’s work – he liked to crop the viewpoints of his paintings and sketches to create a different atmosphere. The coolly returned stare reverses the traditional relationship between viewer and subject, and emphasises Degas’ progressive approach to painting.
#Degas #painting #sketch #Paris French artist Edgar Degas died #onthisday in 1917. Today we’ll feature works that showcase his radical approach to framing subjects, and his subtle handling of form and tone. This vivid oil sketch from 1876–1877 depicts a repeated motif in Degas’ work – the Parisian ballet. He captured both performances and behind-the-scenes moments in his paintings and sketches, often using vantage points that give a fly-on-the-wall impression to his work. Degas worked rapidly but precisely – mirroring the movements of the dancers he portrayed – and this work is completed in thinned-down oil paint so that his quick brushstrokes could dry quickly.
#Degas #sketch #oilpainting #Paris #ballet Our #SunkenCities exhibition is the first at the British Museum on underwater archaeology. Over the last 20 years, world-renowned archaeologist Franck Goddio and his team have excavated spectacular underwater discoveries using the latest technologies. 
At the mouth of the Nile, the city of Thonis-Heracleion flourished as the main entry point into Egypt. Underwater excavations have found a large harbour, numerous ships and anchors, proving this was an international port. This magnificent monument was crucial to revealing that Thonis (in Egyptian) and Heracleion (in Greek) were in fact the same city. The decree was issued by the pharaoh Nectanebo I, regarding the taxation of goods passing through Thonis and Naukratis. A copy was found in the main Egyptian temple in each port. The inscription states that this slab stood at the mouth of the ‘Sea of the Greeks’ (the Mediterranean) in Thonis.

For centuries nobody suspected that Thonis-Heracleion and Canopus lay beneath the sea. Recorded in ancient writings and Greek mythology, the cities were believed to be lost. After sightings from a plane, a diving survey was organised in 1933 to explore submerged ruins. But it was only from 1996, with the use of innovative techniques and a huge survey covering 42 square miles of the seabed, that underwater archaeologists rediscovered the lost cities. 
Thonis-Heracleion and Canopus were thriving cities long before the foundation of the great port of Alexandria in 331 BC. Finds suggest that they were still inhabited into the AD 700s. The cities’ disappearance was caused by gradual subsidence into the sea – much like Venice today – coupled with earthquakes and tidal waves. This triggered a phenomenon known as land ‘liquefaction’, when the ground turns into liquid. 
This reconstruction shows what the port of Thonis-Heracleion could have looked like, dominated by the Temple of Amun-Gereb. Follow the link in our bio to book your tickets to our #SunkenCities exhibition. © Yann Bernard. © Franck Goddio/Hilti Foundation.
