Here's the info I found alongside this image, but I suspect it's been misidentified. The Romans had a large variety of fibulae, and this could represent one of them, but it looks extremely similar to several Baltic Iron Age fibulae. www.langantiques..... "A 'fibula' is an ancient Greco-Roman clasp or brooch. Here is a sizable, weighty and striking facsimile rendered in silver. Button up your toga! Circa 1890."
