The upper portion of a Roman copper alloy Polden Hill brooch dating to the mid 1st and 2nd Century AD. Only the head, wings, coiled spring and part of the bow survive

The wings survive to a width of 16.1mm. They are cylindrical in form with an open back and oval wing caps, both damaged. Within the recess of are the remains of a coiled spring wrapped around a copper alloy axis bar. The spring has 7 coils, four to the right of the pin and 3 to the left if seen from the front. The pin is broken just after its projects away from the spring. The spring's outer end travels up over itself and through a partial loop above the head of the bow, the upper portion of which is now lost. the spring then curls under itself to continue its second half.

The bow of the brooch is plain, D-shaped in cross section and terminates in an old abraded break. 

The brooch is a medium green colour.

The brooch is 21.4mm long, 16.1mm wide and weighs 4.08 grams.

Bayley & Butcher (2004: 149) note that the method of pin attachment seen on this example is characteristic of Polden Hill brooches. Similar examples are illustrated by Hattat (2000: 300) No.374-5 and Mackreth (2011: 53) No. 1610. Both of which share this definition. The latter two sources date this form to the end of the 1st to the late 2nd century.
