Description: | An incomplete cast copper alloy Roman brooch of Polden Hill type. The wings are semi-cylindrical with perforated sub-circular caps at the terminals holding the copper alloy axis bar. This bar holds the spring. The copper alloy wire of the spring also forms the external chord, running through a pierced lug between the wings. The wire of the spring also forms the pin (at the centre of the spring) which is complete. The wings are decorated with pairs of transverse linear groves towards the terminals and single transverse linear grooves adjacent to the head. The lug between the wings forms the zenith of a tapering raised linear decoration running down the upper portion of the centre of the bow. The bow, which is broadly D-shaped in section, has a humped profile, tapers and is broken towards the foot. There is no catchplate, against which the pin would have been secured. The brooch has a well developed, brown patina. The brooch measures a maximum of 45.4 mm long including the pin, 27.1mm long excluding the pin, and 23.7mm wide across the wings. The brooch weighs 11.97g. Bayley and Butcher (ibid. p159) explain that the Polden Hill type of brooch, "...exhibits a distinctive method of attaching the spring: it is carried in a semi-cylindrical crossbar which has closed ends to secure the axial rod, while the chord is held by a hook or crest on the head." In "Brooch Timeline", based on a review of literature, Worrell (2007) dates Polden Hill brooches to AD75-175. Bayley and Butcher (ibid. p 160) state that the main development of this type appears to have taken place in the West Midlands and that more recent finds have confirmed a concentration in this area.
