The purpose of this note is to discuss a late fourteenth-century tomb slab in the church of Santa Maria della Incoronata in Naples. In the course of collecting material for a study of the medieval tombs of Naples, which the Director of the British School at Rome and the present writer are preparing, this tomb, which is in many ways eccentric to the rest of the series, seemed of sufficient interest to merit treatment on its own.The slab (pl. XXI, 1), of Greek marble, now stands on end, together with six others, against the south wall of the west aisle. When Cesare d'Engenio saw it in the early seventeenth century it was still in situ in the floor of the same aisle. The figure is carved in low relief beneath a delicately traceried canopy with pinnacles and spiral columns, the whole set within a rectangular inscribed frame.
