The Beau Street Hoard: excavation progress

Julia Tubman, conservator, British Museum

As mentioned in previous blog posts, the Beau Street Hoard is not just one huge jumbled mass of coins, but actually at least six separate bags. My excavation plan is to remove these coins bag by bag, to preserve the groupings (which are potentially very significant), and give us a clearer view of the size and shape of each bag.

I had been concerned that the coins might have concreted together to such an extent that identifying separate bags would be very difficult during the excavation, but (fingers crossed!) thus far the removal of individual bags has progressed remarkably smoothly. I have managed to retrieve two whole bags of coins. I have numbered these bags five and six, and they are the two smallest bags at the northern end of the block in the x-ray (five being the smallest).

We were excited to see that bag six almost exclusively contained denarii (the smaller coins with a high silver content discussed in Eleanor’s blog post last week), suggesting that the coins might have been bagged by denomination. Of the approximately 3,000 coins I excavated of this bag, I have cleaned around 1,000, and thus far the latest coins we have date to the third century AD.

There are actually a very small number of coins older than the third century contained within the bag: one coin was minted during Otho’s very short reign (AD 69), and an even older one, worn almost flat, minted at the end of the Roman Republic by Mark Antony (just prior to the battle of Actium in 31 BC).

This means that some of the coins were centuries old at the time of the final deposition of the hoard. As I’m cleaning the coins bag by bag in the order excavated, I haven’t yet got round to cleaning the coins kept in bag five, but thus far these all appear to be radiates.

As you can see in the photographs, it is quite easy to tell where one bag ends and another begins. The orientation of the coins themselves and the very bright blue corrosion helps a lot, but there are also other markers. The bags that held the coins would have been organic in nature (made from either an animal or plant product).My guess would be leather as they would have to be strong enough to hold large numbers of coins. Unfortunately, even organic material which has been treated and processed to form objects doesn’t always survive easily in Britain, which is why most of our surviving artefacts are made from stone, ceramic or metal. With this in mind, I knew that any piece of bag that might have survived would be in very poor condition, and I was prepared to look for scant pieces of evidence preserved in the corrosion generated by the coins.

Happily though, I think that I have found fragments of leather (see the light brown material loosely attached to the coins), exactly where I know the bags would have been. The leather is obviously very degraded, and as the fibre network has broken up, the leather has shrunken and split resulting in the flaky incoherent material we see today. I have taken some samples of this material, and hopefully my identification of this will be confirmed by a specialist soon.

The next stage of the excavation- the removal of bag 2

After three weeks I now have a much better understanding of the size and shape of the hoard. There were no more coins beneath bags five and six, but the x-rays taken through the side suggest this is not the case throughout the rest of the block – we suspect there might be more bags of coins beneath the six already identified.

The area excavated thus far shows that the floor of the cist is obviously not even, but seems to have been dug in a rough pit-like way. As yet I have found no evidence of any kind of wooden box that might have held all of the bags, and as I have found pieces of tile pressed up against the coins, I actually doubt that there ever was.

Given the way in which the bags have been piled (I do not want to destabilise the central bags by removing their supports), and to get an idea of what the bags of coins in the middle of the block look like, I will now begin excavating ‘bag two’ at the southern end of the block. I’m sure there will be more exciting developments to report.

Happy birthday to Bob Dylan! Here’s a portrait of the legendary musician by David Oxtoby.

#coin #turtle #history Born #onthisday in 1859: Sir Arthur Conan Doyle. Here’s his application to study at the Reading Room.
All prospective users of The British Museum Library had to apply in writing, stating their reasons for study there. At the time he applied for a reader's ticket, Arthur Conan Doyle was already well-known as the creator of the great detective Sherlock Holmes, but he had not yet given up his work as a doctor, and in this letter of application he gives his occupation as 'physician'.
As well as his detective stories, Conan Doyle wrote many historical novels. At the time he wrote this letter he was probably carrying out research for his novel The White Company, which is set at the time of the Thirty Years' War (1618-48) in Europe.
#author #library #museum #BritishMuseum #history Mary Anning was born #onthisday in 1799, one of the most famous fossil finders of her day. This large skull and lower jaw of an ichthyosaur was found by her at Lyme Regis in Dorset in 1821. You can see it on display in the Enlightenment Gallery (Room 1), on loan from the @natural_history_museum.

#history #fossil #dinosaur Albrecht Dürer was born  #onthisday in 1471. Here’s his wonderful drawing of a woman from 1520.
This study is drawn with a brush in black and greybodycolour. The light is strongly shown by white heightening when it falls onto the woman's face and hair. The light falls down the exact centre of her face. On the left, only the protruding eyelid and cheek bone catch the light. Her eyes are closed and her head centred, its outline strongly marked by black line and silhouette.
By 1520, the date of this drawing, Dürer was deeply interested in the ideal, human form. He had made numerous life studies, both male and female. He had also travelled to Italy and studied classical sculptures and their proportions. For Dürer, the chief purpose of these theoretical studies was to discover the mathematical proportions of the ideal human body. These he would then use in his paintings (portraits, altarpieces and images of saints) and prints. 
#Dürer #art #drawing #history The Enlightenment Gallery in the Museum (Room 1) shows how people saw the world in the 18th century.
The #Enlightenment was an age of reason and learning that flourished across Europe and America from about 1680 to 1820. This rich and diverse permanent exhibition uses thousands of objects to demonstrate how people in Britain understood their world during this period. It is housed in the King’s Library, the former home of the library of King George III.
Objects on display reveal the way in which collectors, antiquaries and travellers during this great age of discovery viewed and classified objects from the world around them.
