Complete but damaged enamelled copper-alloy disc brooch dating from the Roman period, c 2nd century AD.

Description: The brooch is circular with a decorated obverse and plain reverse. A chunk of the disc with the catch plate below are broken off and missing. The sprung pin and catch arrangement are on the reverse. The plate is decorated with three fields of champlevé enamel, the central field is circular and has no clear enamel remaining. The first/inner ring may have been plain or possibly was decorated with moulded dot. The next ring was filled with green enamel with moulded dots inside, around the entire length of the circle. It follows another cast ring, then a ring cell filled with dark cobalt blue enamel - this is the outermost ring. Most of the enamel is degraded.

The spring and catch arrangement on the reverse are of standard type with two raised, pierced lugs holding the axis bar for the spring in place and the pin laying across the entire diameter of the brooch.

Discussion: Hattatt (2000) illustrates a number of similar examples most notably no.1564 . These brooches all date to the 2nd century AD (Hattatt 1987, 167) Some similar examples are also known from the Lower Rhineland and Pannonia, although not from the upper Rhineland area. In general these large enamel disc brooches with few lugs or chain loop tend to be quite uncommon and there is a large degree of variation between their decorative designs so a creation of sub-types and based on such elements is difficult as is drawing parallels.
