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.

  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.

This week we’re highlighting the work of our #AfricanRockArt image project. The project team are now in the third year of cataloguing, and have uploaded around 19,000 digital photographs of rock art from all over #Africa to the Museum’s collection online database.

This photograph shows an engraving of a large, almost life-sized elephant, found on the Messak Plateau in #Libya. This region is home to tens of thousands of depictions, and is best known for larger-than-life-size engravings of animals such as elephants, rhino and a now extinct species of buffalo. This work of rock art most likely comes from the Early Hunter Period and could be up to 12,000 years old.

Follow the link in our bio and explore 30,000 years of stunning rock art from Africa. Watch the incredible discovery of this colossal statue, submerged under the sea of thousands of years. This colossal 5.4-metre statue of Hapy was discovered underwater in what was the thriving and cosmopolitan seaport of Thonis-Heracleion. It once stood in front of a temple and would have been an impressive sight for traders and visitors arriving from the Mediterranean.

Come face to face with the ancient Egyptian god Hapy for yourself in our‪ #SunkenCities exhibition, until 27 November 2016.

The discovery of this stela, which once stood at the entrance of the main entry port into ancient Egypt, was an extraordinary moment. Its inscription detailing taxes helped solve a 2,000-year-old mystery!

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 the cities of Thonis and Naukratis, and it originally stood in the Temple of Amun-Gereb. The inscription states that this slab stood at the mouth of the ‘Sea of the Greeks’ (the Mediterranean) in Thonis.

A bilingual decree found in 1881 refers in its Greek inscription to ‘the Temple of Heracleion’ and in hieroglyphs to ‘the Temple of Amun-Gereb’. Together these objects revealed that Thonis and Heracleion were the same place.

For centuries nobody suspected that the #SunkenCities of Thonis-Heracleion and Canopus lay beneath the sea. Recorded in ancient writings and Greek mythology, the ancient Egyptian cities were believed to be lost.

Over the last 20 years, world-renowned archaeologist Franck Goddio and his team have excavated spectacular underwater discoveries using the latest technologies. The amazing rediscovery of these lost cities is transforming our understanding of the deep connections between the great ancient civilisations of Egypt and Greece.

#archaeology #diving #ancientEgypt This week we’re highlighting some of the incredible clocks and watches on display in the Museum. Mechanical clocks first appeared in Europe at some time between 1200 and 1300. Their introduction coincided with a growing need to regulate the times of Christian prayer in the monasteries. Telling the time with a sundial was especially difficult in western Europe with its unreliable weather. From the end of the 13th century, clocks were being installed in cathedrals, abbeys and churches all around Europe.

The design of turret clocks (public clocks) changed little over the following three centuries and this particular example, made around 1600, has similar characteristics to clocks made for churches in the medieval period. The maker of this clock was Leonard Tenant, one of the most prolific makers of church clocks in the first half of the 17th century. The clock was installed in Cassiobury Park, a country house near Watford.

See this incredible clock in Rooms 38-39 
#clocks #watches #horology When clocks and watches were invented around 1200, sound, touch and illumination were all used to read the time in darkness. This was significant because electric lighting did not become widespread until the 20th century.

This photograph shows a detail from a night clock by Pietro Tomasso Campani made in 1683. When it is dark, light from an oil lamp behind the dial shines through the cut-out Roman numerals enabling the time to be read. Each hour, the numeral for that hour moves round the dial. This ‘wandering hour’ dial was invented by the makers of this clock.

You can see this clock in a new display of clocks and watches in our Members’ Room, just one of the many benefits of becoming a Member of the British Museum. Find out more about Membership at www.britishmuseum.org/membership
