Roman copper alloy bow brooch of Colchester derivative, Polden Hill (Mackreth 2011, Part 3, Group 4, flat wing cap type), c.f. Mackreth 2011, 4.l, Plate 48. and of 1st to 2nd century AD date.
The brooch is fragmentary missing the leg and wings (with a surviving length of 29.0mm, a surviving depth of 10.9mm and a weight of 3.8g). The brooch employed a spring mechanism, now missing, probably behind wings with perforated terminals, now lost (with a surviving width of 11.9mm). Above the head is the remnant of a hook to tension the chord. The head has curved mouldings on the sides (giving a width of 8.5mm). Much of the decorative detail on the brooch has been lost; there is the suggestion of a midrib running along the bow, now heavily worn and corroded. The bow is of D-shaped section, with straight sides gradually converging to the break. A slight rib on the rear of the bow, above the break suggests the start of the catch-plate. The surface has a dark-brown patina with areas of bright green corrosion.
