Bantry Iron Age Fibula

I was in the Cork city museum again today, sketching some Iron Age finds. One of the finds they have there is this fibula found in Bantry, co. Cork. What is really interesting about this fibula is that it is Roman in style, most likely in the Iron Age, the people, or a person, around Bantry was trading with the Roman Empire and one of the things they traded was this Fibula. Of course its possible too that this is a native copy of a foreign style as well. A fibula was used to fasten clothing and cloaks, the earliest finds that I know of are actually Scandinivian from the Bronze Age, but the safety pin design lasted the ages and was used and reinvented for a long time after, as this Roman style one shows
