Medieval copper alloy seal matrix of 13th or 14th century date
The seal matrix is near-complete with corrosion and peripheral loss to the edges of the seal die. The matrix has a hexagonally-faceted handle with a suspension loop at the apex (with a length of 19.7mm and a weight of 4.0g). The handle is narrowed around the suspension loop (with a thickness of 3.0mm and a diameter of 2.5mm) and with no moulding evident at the base of the loop. The seal die was circular but is now eroded (with maximum surviving diameter of 14.8mm). The central device is a capitol letter 'E' in Lombardic script. The surrounding legend is mostly corroded and lost but a few letters are evident and may be suggested:
*C E I [ ] N [ ] A
The legend is difficult to interpret. The surface is corroded with with traces of dark-green patina surviving.
