Copper-alloy, 13.42 grams, 43.10 mm. 1st-4th century AD. Bow brooches moulded as dolphins are known from the early and late Roman periods in Britain, where they occur alongside the more normal plate brooch zoomorphs. The present example is carefully modelled with a rolled upper lip, scale detailing on the body, erect ribbed fin and ribbed, forked tail. The sturdy pin is fused to the spring lugs and catchplate.
