Roman copper alloy brooch of Colchester derivative, Polden Hill (Mackreth Part 3, Group 4.l, flat wing ends type), dating to the 80-160 AD The brooch is near complete, missing the pin and catch only, and has a length of 53.7mm and a weight of 10.3g. The spring mechanism is still in place and was secured by a Polden Hill type arrangement, with pierced lugs at the terminals of the wings. A claw was employed to tension the chord on the head. The wings have a width of 20.5mm and have expanded circular terminals (8mm diameter), which are angled towards the rear. The sides of the bow have curved mouldings at the head and have a width of 10.5mm. The upper bow is of D-shaped section with straight sides converging towards the foot. The bow is decorated with a single central groove running from the claw at the head to the foot. The foot knob has a diameter of 6.1mm and is below a horizontal moulding. The catch-plate begins as a rib beneath the head and arcs out at the leg. The surface is generally well-preserved with a pale green to brown patina.
