In endeavouring to affix a nationality to existing jewels, the only really serviceable landmarks are those furnished by the collections of engraved designs by German and French masters of ornament; and when these are compared with the contemporary work just spoken of, the common origin of nearly all becomes at once evident. Bearing in mind the skill and fame of the Italian goldsmiths, not only of Cellini, but of his contemporaries, such as Girolamo del Prato, Giovanni da Ferenzuola, Luca Agnolo, and Piero, Giovanni, and Romalo del Tovaloccio, the reason why the vast majority of extant jewels should follow German designs is difficult to understand. An authority no less reliable than Sir A. W. Franks has expressed an opinion that the designs of Dürer, Aldegrever, and other German artists were extensively used in Italy.[123] Italian goldsmiths did not produce any such examples of engraved ornament for jewellery as did their confrères in Germany, France, and Flanders; but the current knowledge we possess of the art of the period renders it at least unlikely that the individuality which is the key-note of all the productions of the Italian Renaissance would have countenanced there, in Italy, the use of extraneous ready-made designs. Certainly artists of the stamp of Cellini would not have used them. One is forced nevertheless to acknowledge the possibility of minor Italian craftsmen having executed jewels from German engravings. The international character visible on so many art objects of the time must be attributed in no small degree to the circulation of such designs in almost all the workshops of Europe. [123] _Proc. Soc. Antiq._, XIV, p. 180. A reason for the many difficulties that arise in connection with this particular question seems to lie in the fact that for causes unexplained the jewellery of the first half of the sixteenth century, whether Italian, German, or of other nationality, has almost all vanished, and that examples met with at the present day belong chiefly to the second half of that century. While acknowledging the existence of a fair number of jewels whose authorship cannot be otherwise than Italian, and without denying the possibility of the survival of examples of jewellery even from the hand of Cellini himself, a protest must be raised against the practice, hitherto so common, of describing _every_ jewel of the sixteenth century as Italian, and of coupling _every_ high-class object of this description with the magic name of Cellini.
