Description: | A complete cast copper-alloy Roman brooch of the Polden Hill type. At the head are the characteristic wing tip plate extensions, pierced to take the extant, square-section axis bar. The rearward facing lug which protrudes from the centre of the head holds the chord of the spring mechanism. The spring survives with minor losses, four coils either side. On one side the coil turns into the central pin, which may have suffered some losses at its tip. The semi-cylindrical wings that cover the spring and have tips that rise slightly to form a ridge. There is a groove within the ridge, with a further thin ridge beyond. There is a further pair of ridges, one either side of the head. These and the terminal ridges are decorated with fine transverse incised decoration. The bow is triangular with rounded corners in cross section. At the head end it is stepped on either side and features a median ridge which extends from the chord lug to just beyond the stepped sides. There is a small notched removal just above the perforation for the chord on the front edge. The bow tapers from a width of 7.7mm at head to only c. 1.8mm at the foot. For the most part the bow is straight, having curved through c. 135 degrees at the head end. The sub-triangular catchplate survives well and has a triangular perforation. The curved element which retains the pin is 20mm long. It is delineated by a longitudinal incision. There is a double transverse incised motif at the 'head' end, with a further one around half way along. Between the two, and between the second and the terminal, is a diagonal incision. The brooch has a mid-dark green patina with substantial traces of tinning all over. Some breaks to the spring and wing tip have been repaired by the finder.
