Rorschach; Switzerland; St. Konstantius detail of head and chest. The skeleton of a presumed martyr from the Roman Catacombs arrived in the town's church of St. Kolumban in the 1670s. It is still in situ in the predella of an altar on the right side of the nave; but is normally hidden beneath a painted cover. Little is known about the decorator of the relic; but this detail shows that the work done to the head and chest was of exceptional quality; involving real and imitation gemstones; beading; and filigree wire.
