Description: | An incomplete cast copper alloy Polden Hill brooch from the Roman period. The brooch consists of the head, bow, a crossbar formed by two semi-cylindrical horizontal wings with pierced sub-circular end-caps (one is incomplete), and a hook on the head. The wings would have held the axis bar, spring and pin, all of which are missing, and the external chord would have been secured by the hook (for a description of the Polden Hill type, See Bayley and Butcher, 2004 Roman Brooches in Britain: A technological and Typological Study Based on the Richborough Collection Society of Antiquaries p. 33-34 and p159). There is a collar where the wings meet the head. Both of the wings have a vertical linear rib at the terminals, highlighting the end caps. There is a recess in the reverse of the head, within the hollow (concave) reverse of the crossbar. The bow, which has a humped profile with a sub-oval, almost D-shaped cross-section, 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 green patina. The breaks on the bottom of the bow and one end-cap do not appear to be recent. The brooch is 26.0 mm long, 19.0mm wide is 14mm from front to reverse. It weighs 8.3g. 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 her "Roman Brooch Timeline", 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 region.
