For those who have been following the progress of the conservation of the Beau Street Hoard on the blog, I am delighted to announce that all the coins – around 17,500 of them – have now been cleaned to required identification standards, that is, to the point where the legend and significant features are readable. Conservator Julia Tubman carried out the bulk of this work on the c.17,500 coins contained within the hoard. Additional work has been carried out on a small number of these coins and conservation has also been carried out on c.400 coins that were initial finds from the outer edges of the hoard, before the hoard proper was unearthed. This last group of coins were in particularly poor condition and most required substantial chemical and manual cleaning. These coins were held in numbered paper envelopes, some of which corresponded to small find numbers allocated when the hoard was excavated.

The soil block that held the hoard has now been dismantled and returned to the archaeologists who carried out the initial excavation for final sifting and checking for palaeoenvironmental remains: that is, material that might provide further contextual information about the coin hoard.

At the time of Julia’s last post, she reported that one of the coin clusters (bag 4), had been scanned. As with the other coins in the hoard, the clustered corroded coins retained the positions that they would have held in the bag in which they had been deposited. In this instance the bag shape was particularly well preserved. The initial scan was carried out at the British Museum by Martin Cooper of the Conservation Technologies Unit, National Museums Liverpool (NML). The scan data was used to create a 3D computer model, which was then 3D printed to make a replica of the coin bag using Selective Laser Sintering (SLS), a process that uses a laser to fuse particles of plastic or other material into the required three-dimensional form. A plaster cast was then made from the print and this was painted to resemble the original coin cluster, by conservators at NML.

The replica has proved very popular among visitors to the Roman Baths and was shown at a Beau Street Hoard community consultation event run by staff at the Roman Baths earlier in 2013. Members of Bath Ethnic Minority Senior Citizens Association (BEMSCA) were among those who handled the replica. As a three-dimensional record of the original form of the coin bag, which of course no longer exists now that the coins have been conserved, the replica is an excellent supplement to the information gathered about the hoard, an invaluable means of allowing people to gain some sense of the physicality of (at least part) of the hoard.

Further exciting news is the forthcoming analysis of what appear to be animal skin remains from the bags used to store the coins. In one of Julia’s earlier posts she noted that traces of what appeared to be skin product, preserved by metal corrosion products, were found on the outside of each cluster of coins, suggesting that leather bags may have been used to house the coins. Professor Matthew Collins and colleagues at BioArCh (University of York), are hoping to extract collagen from the samples provided and to identify the species of animal skin used. Identification of the animal species will be made by peptide mass fingerprinting, an analytical technique for protein identification. We look forward to hearing the results of their investigations.

There have been some beautiful sunsets in London recently – we love the way @wiserain23 has captured the streaks in the sky over the Museum in this shot. The orange and peach colours in the sky have been spectacular during this spell of cold, crisp but sunny weather. You can see the Museum lit up like this if you visit during our Friday late opening – you can browse the galleries until 20.30. Remember to share your photos with us by using the British Museum location tag – we love seeing our visitors’ photos, so get snapping! #BritishMuseum #London #sunset #sky #lights #evening #regram #repost Don’t forget to look up! ☝🏼 The triangular feature above the columns of the Museum’s main entrance is called a pediment. Originally it had a bright blue background and the statues were all painted white. 
The sculptures in the pediment show the development of ‘mankind’ in eight stages – a very old-fashioned idea now, but it was designed and built in the 1850s. The left side shows the creation of man as he emerges from a rock as an ignorant being. He meets the next character, the Angel of Enlightenment who is holding the Lamp of Knowledge. From the lamp, man learns basic skills such as cultivating land and taming animals.

The next step in the progress of civilisation is for man to expand his knowledge and understanding. The following eight figures represent the subjects he must learn to do this – architecture and sculpture, painting and science, geometry and drama, and music and poetry. The final human figure, on the right, represents ‘educated man’. Learn more about the Museum’s architecture and its fascinating history in our new blog – follow the link in our bio! We’d love to hear what you think. 258 years ago we opened our doors to the public for the first time! The British Museum is the world’s oldest national public museum, founded in 1753. It was created to be free to all ‘studious and curious persons’ and it’s still free today, but a few things have changed…

Did you know that the @natural_history_museum used to be part of the British Museum? The Museum’s founder Sir Hans Sloane had collected a vast number of natural history specimens, and these were part of the Museum’s collection for over a hundred years. In the 1880s, with space in Bloomsbury at a premium, it was agreed that these collections should move to a new site in South Kensington.

This photograph by Frederick York shows a mastodon skeleton on display here in Bloomsbury, before it moved to South Kensington in the 1880s.

Explore more of the Museum’s history on our new blog – follow the link in our bio and let us know what you think! The British Museum opened to the public #onthisday in 1759, the first national public museum in the world! 🎉

The Museum was founded on the death of Sir Hans Sloane, who bequeathed his collection of 71,000 objects to the nation. The British Museum Act gained royal assent in June 1753 (which makes us older than the USA!). The original collection featured 1,125 ‘things relating to the customs of ancient times’, 5,447 insects, a herbarium (a collection of dried plants), 23,000 coins and medals and 50,000 books, prints and manuscripts.

This photograph of the front of the Museum was taken in 1857 by Roger Fenton, the Museum’s first official photographer.

To mark this anniversary, the Museum is launching a blog where you can find all kinds of interesting articles – things you didn’t know about the Museum, curators’ insights, behind-the-scenes stories and more. Follow the link in our bio – we’d love to know what you think! In the early 1830s, following the success of ‘Thirty-six views of Mount Fuji’, #Hokusai worked to produce several follow-on print series. These featured waterfalls, bridges, and the flower series depicted in both large and small sizes. Hokusai probably composed this design without seeing the waterfall or referring to an existing image. He was free to use his imagination, and produced a strikingly idiosyncratic print that contrasts the marbled currents at the top with the perpendicular drop of the falls. Three travellers warm saké (rice wine) as they enjoy the view.
Our upcoming exhibition will explore Hokusai’s iconic work, and allow you to learn more about his enigmatic life. The exhibition opens on 25 May 2017 – learn more and buy tickets by following the link in our bio.
The exhibition is supported by Mitsubishi Corporation.
Katsushika Hokusai (1760–1849), Amida waterfall, deep beyond the Kiso highway. Colour woodblock, 1833. The Tōyō Bunko, Tokyo. On display 7 July – 13 August 2017.
#Hokusai #waterfall #Japan #JapaneseArt #print #nature #landscape Our #Hokusai exhibition will feature stunning works – from dramatic landscapes to exquisite depictions of birds and flowers, like this bullfinch. He worked tirelessly to capture what he called the ‘form of things’ and to show how they relate to one another. Hokusai has depicted a male bullfinch, distinguished by its pink marking from cheek to throat. The bird and flower stand out in relief against the background of deep Prussian blue (a colour that had only recently been invented, used to great effect by Hokusai).
The exhibition ‘Hokusai: beyond the Great Wave’ will open on 25 May 2017. With many of the works coming especially from Japan, it’s a rare opportunity to see the artist’s work on display in the UK. Follow the link in our bio for more information and to book tickets! 
Join us for a #FacebookLive broadcast later today at 17.30 GMT and ask your questions to our Hokusai curator Tim Clark! 
Katsushika Hokusai (1760–1849), Weeping cherry and bullfinch. Colour woodblock, 1834. On display 7 July – 13 August 2017.
