Manufacture, wear and repair of the Chiseldon Iron Age cauldrons


Jamie Hood and Alexandra Baldwin, British Museum

With the Iron Age Chiseldon cauldrons excavated and cleaned to expose the metal surface we are beginning to see interesting technological features and evidence of manufacture revealing them to be sophisticated and high status objects.

Although they’re over 2,000 years old, different tool marks from shaping and thinning the copper alloy are preserved on the surface of the metal. These suggest the careful and deliberate use of specific tools for different jobs, indicating that the objects were made by a craft specialist skilled at working sheet metal.

Other features likely to relate to construction are the lines, faintly incised into the surface of the sheet copper-alloy and only visible in raking light. These appear to mark the overlap of plates making up the sections of the cauldron, and the regular distribution and position of rivets indicating that the cauldrons were carefully designed and made.

Examination is also showing that, while the 12 cauldrons are broadly similar in their design, there are variations in their size, shape and construction. We have already identified three different types of rim construction. These differences are extremely intriguing and suggest that the cauldrons were made by different makers and/or at different times.

Another intriguing feature we are encountering is a high number of patched repairs. Some repairs appear to have been applied at the time of construction and placed over fatigue cracks caused by raising the metal. Others quite clearly cover areas of damage caused during the useful lifetime of the cauldrons, indicating that they were used and repaired over a period of time and were already old and well-loved items at the time of their burial.

Preserved details like this mean that while the cauldrons are in relatively poor condition there are minute pieces of evidence that allow us to build up a wider picture of how the cauldrons were designed and made, and really bring the objects to life by allowing us to see the craftsman’s thought process and the practical application of their art.

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.

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.
