The Beau Street Hoard: counting ancient money

Beau Street HoardEleanor Ghey and Henry Flynn, British Museum

If you listen carefully outside the Department of Coins and Medals at the moment you may hear the chink of money being counted. It’s not a surprise donation or a lottery win, but Roman coins from the Beau Street Hoard being sorted into imperial reign, bag by bag, to obtain an idea of the date and contents of the hoard.

We collected the coins from conservator Julia Tubman in stages, as each bag was removed from the soil block the hoard was found in. Some are surprisingly heavy, about as much as I can lift comfortably. The silver coins have a pleasing weight in the hand and do not look over 1,700 years old.

The next stage of our work is to provide information on the hoard so it can be given a provisional valuation as part of the Treasure process. The hoard has already been declared Treasure at inquest under the Treasure Act 1996. Now the coins are almost all separate and reasonably clean, it will be possible for an independent expert to do this. As museum curators, we do not have expertise in questions of commercial value but we provide a listing of the contents. The provisional value is then considered by the Treasure Valuation Committee, which recommends a final value. The purchasing museum (in this case the Roman Baths Museum) is then able to raise funds for this amount, from which a reward is paid to interested parties (usually the finder and landowner) as applicable.

The results so far…

We have been able to sort and count seven of the eight Roman money bags contained within the hoard – one is still undergoing conservation. The total so far is 14,646 coins, but as the final bag is large we expect this to go up to over 16,000 coins.

In my previous post I described the three different types of coins in the hoard (denarii and early (silvery) and later (debased) radiates). With these three types of coins one might expect a wide date range between the bags. This has not been the case. We have the very latest denarii and late silver radiates, so that the bags could have been deposited within 20 to 30 years of each other (or sorted and re-deposited together). At the moment, the latest coins in the hoard date to the mid AD 270s quite precisely.

A conservation-themed display of the Beau Street Hoard is now on show in Case seven of the Citi Money Gallery. This case focuses on Treasure and hoarding and features a changing display intended to highlight new or exciting Treasure finds. The Beau Street display focuses on the excavation of the soil block and subsequent cleaning of the coins by Julia Tubman.

The content of the hoard is represented by three piles of coins – one pile of each denomination found in the moneybags – and the seven-week process of excavation and cleaning is illustrated using time-lapse video footage of the removal of the coins from the soil block.

An X-ray image, which provided the first visual evidence of the grouping of the coins and acted as a guide for the excavation, is also featured in the video. Some of the tools used by Julia during this process are displayed alongside the coins which have been cleaned for identification.

Our #AfricanRockArt project team is cataloguing and uploading around 25,000 digital images of rock art from throughout the continent. Working with digital photographs has allowed the Museum to use new technologies to study, preserve, and enhance the rock art, while leaving it in situ.

As part of the cataloguing process, the project team document each photograph, identifying what is depicted. Sometimes images are faded or unclear. Using photo manipulation software, images can be run through a process that enhances the pigments. By focusing on different sets of colours, we can now see the layers that were previously hidden to the naked eye.

This painted panel, from Kondoa District in #Tanzania, shows the white outline of an elephant’s head at the right, along with some figures in red that it is possible to highlight with digital enhancement.

Tanzania contains some of the densest concentrations of rock art in East Africa, mainly paintings found in the Kondoa area and adjoining Lake Eyasi basin. The oldest of these paintings are attributed to hunter-gatherers and may be 10,000 years old.

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.

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.
