Title |
Iron Age Colchester one-piece brooch |
||
Description |
English: An incomplete cast copper-alloy Colchester one-piece brooch dating to the Iron Age (c. AD 25-60). The brooch comprises the wings, hooks, bow and catch plate. The spring and pin are missing.
The wings are flat and rectangular in shape and cross-section. On the reverse, a forward-facing circular-sectioned hook that would have held the external chord projects from the upper edge of the wings, and beneath this another one from the lower edge, the point of which rests on the hook above. The bow, projecting from the centre of the wings, is D-shape in cross-section and is curved pronouncedly, narrowing and transitioning to circular-sectioned along its length. It terminates at a coiled point as a foot. Projecting from the reverse of the bow just above the foot are the remains of a flat triangular-shaped catch plate in two parts. The missing section may well have been decorated with rectangular or square perforations. The wings, bow and catch plate are otherwise undecorated. Most of the surfaces have dark brown patination while the upper bow and wings have additional patches of light green patina in several areas. The brooch measures 58mm long. The wings are 19.5mm long, 5.2mm wide and 1.2mm thick. The top of the bow is 5.2mm wide and 3.9mm thick, the lower bow 3.2mm diameter just above the catch plate, and the catch plate 0.5mm thick. The brooch weighs 10.71 grams. For a similar brooch with complete catch plate see Mackreth 2011, vol. 2, p. 25, plate 22, no. 626. |
