Description: | Incomplete cast copper alloy one piece Colchester brooch of late Iron Age to Early Roman date (1-75 AD). The head of the brooch is relatively small and two small stumpy wings extend from either edge. The wings are short and solid with a semi-cylindrical cross section. The spring is formed from a coiled length of copper alloy wire which has been integrally cast with the body of the brooch. This wire extends from the reverse head of the brooch and has been coiled to form the spring which is formed from six turns and secured by an integral external chord to a rearward facing hook. The cast hook is located at the centre of the wings on the upper edge of the head of the brooch and secures the external chord of the spring using a reverse shaped (anticlockwise) shaped hook. The bow head is slight with an angular profile. The bow is D shaped in cross section. It tapers to an abraded broken point. The catchplate, pin and pin rest are all missing. It is likely that the foot would have been pointed. The brooch measures 44.5mm length, 14.8mm width (across wings and spring), 4.6mm width across bow, is 3.1mm thick across the bow, and weighs 4.53 grams. The brooch is much abraded and distorted. There is no evidence for decoration - although this may have been lost through abrasion and corrosion. The brooch is a mid grey green colour with a much abraded patina. Where abrasion has occurred it is most evident on the external faces of the brooch. This has revealed a brown coloured metal. Where this has occurred a light green powdery corrosion product is visible. Movement in the plough soil has also distorted the profile of the brooch. Similar brooches can be seen in Richard Hattatt's Visual Guide to Ancient brooches pp 296 fig; 155 and Bayley and Butcher: Roman Brooches in Britain pp 60-63. This type of brooch spans the period pre and post Roman conquest of Britain and it is difficult to therefore suggest either a purely Roman or Iron Age date
