It has been argued that the present relief shows episodes from the life of Saint Clair d'Epte, a bishop martyr who has given his name to a region in Normandy. In the upper register the bishop is shown after his martyrdom, in the act of presenting his head to the Virgin. In the lower register two men are seen peering into the well from which, according to the legend, the saint's head was recovered. In that case, it may be presumed that the figures of pilgrims, identified by their distinctive staffs and hats, are associated with the cult of Saint Clair.
If the identification of the bishop saint is accepted, then it seems reasonable to suppose that the origin of the relief is French, although it is no less clear that its carver was profoundly influenced by German late Gothic sculpture in the facial types, the treatment of the draperies, and the unusually bold undercutting.
