The object I propose to describe is a Disc of silver of very thin substance, being scarcely one-sixteenth of an inch thick, and beaten up from behind in the kind of metallic work called sphurelaton by the Greeks. It has apparently formed the top of a mirror-case, or box. (See Plate XXI.) The account of its discovery, which Mr. Vint, its possessor, has placed in my hands, is as follows :—“This bas-relief I purchased in Naples upwards of twenty years ago of a travelling jeweller, who collected and dealt in relics of antiquity. The following, to the best of my recollection, is the account he gave me of the place where it was found, and the manner in which it came into his possession. On one of his customary visits to Tarentum, in Calabria, he was invited by a silversmith, with whom he transacted business, to take some refreshment, and on entering a room behind the shop he observed this bas-relief placed against the wall, and two small lamps burning before it. Being at the very first sight sensible of its antiquity, he carefully asked the silversmith's wife, who was present, where it was found. Her answer was to this effect. Some excavators brought to their shop for sale a quantity of silver which they had found in digging among the ruins of the old city. On breaking up the mass her husband discovered these figures within it, and was about to put them into the crucible to melt them, when she snatched the rare relic from her husband, exclaiming with religious horror, ‘Would you melt the Madonna?’ Her husband confirmed his wife's account, and moreover stated it was soldered within a conical-shaped silver vase that was found covered up in the tight cavity of a large stone among the ruins of Tarentum.”
