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.

We love this brilliant sketch of the Great Court by @simoneridyard! It captures the subtle blues and greys of the inside of the space. The Museum has always played host to artists throughout its history, and we still see people sketching their favourite objects or views inside the Museum (although most people take a photo with their phones now!). Have you made drawings while visiting any museums or galleries? We’d love to see any art made in the Museum – tag your photos with the location and we’ll regram our favourites! #BritishMuseum #London #regram #repost #museum #art #sketch #sketchingfromlife The Lion of Knidos looks very regal in this super photo by @nin_uiu. The Lion is named after the place where it used to stand, an ancient Greek city in modern-day Turkey. A colossal statue weighing six tons, it was part of a funerary monument that stood on a headland above a cliff. The lion’s eyes were probably inlaid with glass, and this may have aided sailors navigating the rugged coastline – they could use the reflection of the eyes to determine where the coast was. The sculpture is made from one piece of marble, but it’s not known exactly when it was made and estimates range from 394 BC to 175 BC. #BritishMuseum #history #AncientGreece #AncientGreek #lion #sculpture #statue #London 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!
