Silver & copper-alloy, 28.75 grams, 58.53 mm. Roman brooch with copper-alloy pin and spring; circa 2nd century AD. The form is derived from the 'trumpet' type and this example is very similar to brooches found at Pannonia; with simplified semi-circular head and a large corresponding projection at the centre. The foot terminal is enhanced with a small moulded panel and plain catchplate; this last showing some minor damage. The one-piece spring and pin assembly passes through a central projection at the rear of the brooch head. Reference: Iron Age and Roman Brooches by Richard Hattatt, figure 28, for similar pieces. Very fine condition. This item is accompanied by an XRF ancient metal test certificate from Oxford X-ray Fluorescence Ltd.
