Object type certainty: Certain
Workflow status: Awaiting validation

A Roman copper alloy two-piece Colchester brooch (dolphin) (43-65AD). The brooch has a lug behind the head pierced (now broken) to take an axial bar threaded through the spring and its chord is held in the pierced lug. The spring, axial bar and pin are missing. The lug continues as a decorative crest down the bow, resembling the rearward hook of one-piece Colchester brooches. The crossbar has perforated end plates, again to hold the axial bar in place, and is decorated with a groove as a border at each end. The catchplate is solid and there is a small flattened globular foot. There are traces of white metal coating, probably tinning, remaining.

Dimensions: length: 31.74mm; width: 19.43mm; thickness: 18.08mm; weight: 5.70g.
