File:Enamelled brooch plate from Roman chatelaine brooch (FindID 182549).jpg

English: Roman brooch; Cast copper alloy brooch plate from a chatelaine brooch with enamelled decoration. Dated to the 2nd century. The plate is in the shape of a broad, horizontal rectangle surmounted by an arch with little lugs around its outer edge. There is a semi-circular gap between the arch and the lower, rectangular band. The two bottom corners of the plate each have a loop descending, which would have held the axis pin for the chatelaine attachments. The pin hinge is present on the back, although the pin is missing. The rectangular band is decorated with a repeating scrollwork pattern in blue and yellow enamel on a red enamel ground. The arch is decorated with a sawtooth design in similar red and blue enamel and the four outer lugs are likewise enamelled in red. The brooch is damaged, in that the very top of the brooch plate has been torn away and is missing.

Width (across chatelaine pin axis) 40.2mm, height (top of remaining section of plate to bottom of chatelaine pin loop) 35.6mm, thickness (plate) 2.3mm, thickness (inc pin hinge) 10.1mm, weight 14.43g
