Title |
Roman Wirral brooch (front, profile, reverse) |
||
Description |
English: Cast copper alloy enamelled Wirral brooch. Length: 46.6mm, width: 11.4mm, depth: 18.6mm, mass: 12.5g. Roman period (1st-2nd C AD). There is an incomplete loop on the head. The front of the head is stepped and decorated with incised lines. On the back of the head there is a horizontal ridge securing the (incomplete) axial rod, with a central vertical slot for the pin which is missing. The bow is arched in profile with a D-shaped cross section. On the front of the bow there are three reserved rectangular fields with (now incomplete) champlevé enamel in alternate colours. Alternate yellow and ?red enamel remains in the central field. To either sides, turquoise and ?red enamel remains. Below the enamelled fields there are two horizontal grooves and a stud. There is an incomplete catchplate on the reverse of the bow, towards the broken foot. The brooch has a well developed brown patina, although where this has been lost, particularly on the sides and raised features of the brooch, the surface is light green and pitted.
In the PAS “North Regional Newsletter”, Winter 2007, McIntosh comments that, “…it is thought that they could perhaps have originated from the Wirral with only a couple of work-shops making them.” |
