Mediæval ornaments of all sorts are forged at the present day upon the Continent to a considerable extent, though less than are those of later times. One important centre of their production is Paris. Another, in earlier years in particular, was Frankfort, where visitors to watering-places on the Rhine have long been the victims of fraudulent vendors. Such mediæval objects, however well supported by a dealer's warranty of place and time of discovery, require, says Mr. King, to be examined by the amateur with a very suspicious and critical eye. Among other personal ornaments of this period that have received attention at the hands of the forger are the leaden badges known as pilgrims' signs. Many ingenious forgeries of the kind were produced about forty-five years ago, and purported to be brought to light by workmen engaged in excavations near the Thames in the City of London. These were in large part the work of two illiterate mud-rakers on the banks of the river; while articles of like kind were shortly afterwards made by two men known as "Billy and Charley," who manufactured a number of curious pendent medals of lead and "cock-metal."[192] The discovery in the Seine, about the same time, of many genuine pilgrims' signs led to the circulation also in France of a quantity of spurious objects of a similar nature.

Billy and Charley, Rosemary Lane, Tower Hill, is shown in the Cuming Museum, Walworth Road, London. Renaissance pendants, the prizes of the connoisseur, are favourite subjects for reproduction at the present day, for, unlike the earlier objects, they are not ill-adapted for personal use. Jewellery in the Cinquecento style has for several years past been made in large quantities at Vienna. These jewels are generally not in gold, like the works they profess to imitate, but in silver-gilt, and as a result their enamel is never of fine quality, their general appearance is not up to the standard of the old, and their workmanship is mostly very mechanical. Apart from these and similar works, made also in France and generally sold in jewellers' shops as modern productions, there are others which pretend to age. Though one seldom meets with examples that approach the best productions of the Renaissance, objects of the kind are occasionally imitated with such proficiency, that in collecting specimens of early jewellery in no instances is it necessary to exercise greater caution than in those of the Cinquecento.
