Unique ID: LANCUM-4DB9A4
Object type certainty: Certain

status: Published 
An incomplete copper alloy penannular brooch of the Iron Age to Roman Period, dating to 100 BC - AD 100.
About 90% of the brooch remains, the pin is missing. The brooch is sub oval in shape and circular in cross section. It comprises of a thin open hoop. Half way there is a notch or dent in the hoop, this is where the pin would have sat. The terminals are circular in plan and rectangular in cross section. They are made from the flattened end of the hoop, which have been turned up and rolled into a spiral.
The brooch is a dark brown in colour with traces of green corrosion. Abrasion caused by movement whilst within the plough soil may have resulted in the loss of some of the original surface detail.
Fowler (1960) claims that this type of brooch was adopted by Belgic incomers in the First Century BC. This type (Type C) is one that continues in use for a long period and as a result is difficult to date accurately.
