Our chosen find this month is a middle to late Saxon copper-alloy bow brooch. It was found recently on farmland in Breckland and is notable because of its size, richly cast decoration, and excellent level of preservation. It never ceases to amaze that an object can spend well over a 1000 years in the ground, be subjected to the vagaries of the weather, chemical fertilizers and ploughing and still survive in relatively good condition. Not so for the iron spring and pin mechanism though, as the rusty concretion on the back bears witness to the original location. Iron corrodes much more readily than copper alloy in the ground. 

The date of the brooch is circa AD 800-910 and it is of a brooch form now described as Ansate. The term Ansate means ‘handle-shaped’ and it is clear how the brooch style got it's name.  The adjacent distribution map uses national data from the Portable Antiquities Scheme (PAS) database and illustrates that the type was particularly popular in Anglo Saxon East Anglia. Full details of the brooch can be found at https://finds.org.uk/database  using the reference NMS-EB5046 in the search field.

This month we are going back to the Bronze Age to a time when the production, fabrication, development and use of metals was very much in its infancy.  The late Bronze Age knife or razor shown below was found near Swaffham and was probably cast in a two-piece clay mould around 800 to 700 BC.

The metal is Bronze which is comprised of copper and tin alloyed together, but it probably also contained a deliberate addition of lead, as the metal-workers of the time had already discovered that this made the metal more fluid when molten and therefore improved the casting process ⁽¹⁾.  As the drawing shows the leaf-shaped blade is still in surprisingly sharp condition.

Full details of the knife can be seen at www.finds.org.uk using search reference NMS-5BFE67.

November's Find of the Month is this fantastic Middle – Late Bronze Age anvil.

Bronze Age anvils are very unusual finds, probably because the metalworkers who used them were easily able to melt down broken ones to create new objects.

Almost every surface of this example would have been used to work bronze or gold, with either of the two ‘beaks’ being used to secure the anvil to a wooden block so the other could be used to shape the metal. Each working surface has a different form allowing a wide variety of shapes to be created using just this one anvil.

At the time this anvil was in use, the number and type of personal ornaments made and worn by Bronze Age people increased, and this anvil would have been used to make some of them. The metalworker who used it would have been highly skilled and was probably seen as powerful, important or even as having a religious role in society. We suspect this because the way Bronze Age tools were treated shows they had a meaning or significance beyond their use as tools, suggesting the people who made them had a role which extended beyond their skills as craftspeople.
