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.

The mummy case of this temple doorkeeper called Padiamenet is covered with hieroglyphic inscriptions and religious images. The inscriptions on this brilliantly painted cartonnage tell us that he was the Chief Doorkeeper of the Domain of Ra, the Chief Attendant of Ra, and also Chief Barber of the Domain of Ra and of the temple of Amun. This largest scene shows Padiamenet, dressed in a long fringed robe, adoring the god Osiris, who is grasping the royal crook and flail. Behind him stands his sister, the goddess Isis.

#history #mummies #BritishMuseum Peter Paul Rubens was born #onthisday in 1577.
This is a magnificent drawing in both scale and style. It is drawn in black and yellow chalk, though Rubens also used a grey wash and some white heightening in order to bring the animal to life on paper.
The lioness is drawn from behind. Her front paw is raised and her mouth open, the fangs clearly visible. White heightening brings out the lighted area around the tail and the joints of the back legs. Both short and longer chalk strokes are used to suggest the different textures of the fur and mane.
Rubens used this drawing for a lioness in his painting of 'Daniel in the Lions' Den' (1613/15; National Gallery of Art, Washington, DC). The vividness of the drawing is even more remarkable given that Rubens probably based his drawing on a bronze statue of a lion and not a living animal. The strong contour line in black chalk around the animal suggests that he was studying a model. However, Rubens had the gift and genius to invest an unmoving object with both life and movement, even if the highlights give the impression of a metallic sheen.

It is early morning in 1875 in the Main Entrance Hall of The British Museum, and staff are preparing for the public. Until 1878 the Museum was open on Mondays, Wednesdays, Fridays and until midday on Saturdays. Tuesdays and Thursdays were reserved for students. The visiting hours varied with the seasons and during the summer months the Museum stayed open until 8 o'clock in the evening.
Staff stop work as the photographer Frederick York sets up his camera. Two men sit comfortably on a bench at the foot of the stairs. Another two, noticing the photographer, stop halfway down the stairs. As the long exposure needed for this early photograph has already started, their images appear faint and ghost-like. In the foreground is the Piranesi Vase which is now displayed in the Enlightenment Gallery.
#photograph #archive #throwback #tbt #BritishMuseum The @britishlibrary opened at St Pancras #onthisday in 1998!
The British Museum held library collections from 1753 until the British Library was formally established in 1973. In 1759 the first Museum Reading Room opened in Montagu House, the original home of the British Museum. However, as the Museum building developed and the number of readers increased, a series of improved reading rooms were built. Finally, in 1998 the British Library moved out of the Museum’s Bloomsbury site to its new home at St Pancras.
This engraving, from a watercolour by Thomas Hosmer Shepherd (1792–1864), shows the sixth Reading Room, designed by Sir Robert Smirke and completed in 1838. It was used until 1857 when the famous domed Round Reading Room opened.
The sixth Reading Room was in fact two connected rooms, each with an iron gallery at window height. More than 10,000 books were stored on the bookshelves. Originally space was available for 168 people seated at 24 tables. As the number of readers increased another 40 spaces were provided. In 1930 an extra floor was built at gallery height to increase storage space. The lower part of these two rooms has now been converted into the galleries of Mexico and North America (Rooms 26 and 27).
