Recording old cauldrons with new techniques


Stephen Crummy, archaeological illustrator, British Museum

As illustrator in the Department of Prehistory and Europe at the British Museum, I am always looking for the best way to help our curators interpret an object. My role is to produce artwork that shows the form, construction and nature of objects and any decoration on them so that they can be clearly understood. This will usually result in illustration for academic publications and exhibitions as a result of research work on the Museum collection, or excavations.

Traditionally I have produced pen and ink technical drawings but new opportunities are available through various computer-generated methods of recording, analysing and understanding information about objects and excavation. With the Chiseldon Cauldrons material, I am exploring some of the possibilities of these new technologies, and in this case using photogrammetry and laser scanning programs to produce 3D records of the archaeological remains of individual cauldron blocks as they are excavated by Alex and Jamie.

Three-dimensional scan results

Three-dimensional scan results

We are using a laser scanning system to produce 3D computer models of the individual pieces from each cauldron. This is achieved by plotting a thin red laser line as it is slowly moved across the surface of an object. Having recorded each piece we are hoping to use the photogrammetry programme to virtually re-construct the blocks as excavated.

The early results we achieved proved somewhat variable, especially with the laser scanning, but we are now starting to produce some very good quality scans in terms of both modelling and colour accuracy.

The plan is to produce virtual models of each cauldron as excavated which will enable us to understand much better what they would have originally looked like, and how they were made. It is also hoped that an overall plan of the pit and its contents can be reproduced. We’ll also be able to produce artwork for both printed and online publication, and to generate virtual re-constructions for publication and display. As we create interesting images, we’ll also post some of them here on the blog so you can see what we’re finding.

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.
#Hokusai #Japan #JapaneseArt #print #bird #nature #cherry 🌊 Hokusai’s most famous print, known as ‘The Great Wave’, will be one of the highlight works in our upcoming #Hokusai exhibition (25 May – 13 August) . It was created when the artist was in his early seventies and was one of a series – ‘Thirty-six Views of Mount Fuji’ – which celebrated the sacred mountain with views from different seasons and locations. Hokusai increasingly identified with Mount Fuji as a source of long life, even immortality.

The exhibition ‘Hokusai: beyond the Great Wave’ will feature sublime prints and paintings by one of Japan’s greatest artists. Follow the link in our bio for more information and to book tickets!
