Copper-alloy, silver and enamel, 12.79 grams, 54.87 mm. 12th-13th century AD. AD-shaped mount pierced in two places for attachment to a cross, reliquary or other object of veneration. The surface of the mount is silvered and a radiating geometric design is added in champlevé with dark blue-green enamel. On the upper edge is a human head modelled in the round with enamel points for the eyes. The face is tilted upwards and the rest of the mount forms a cloak or chasuble. This class of objects is associated particularly with the Abbey of Grandmont at Limoges under the patronage of Henry II (fl. AD 1133-1189). Reference: cf. Limoges plaques in Robinson, J. Masterpieces of Medieval Art, London, 2008 p.46, 96, 126. Very fine condition. Provenance: from an old English collection.
