We find frequent mention at this time of silversmiths, many of whom came from Germany, France, or Italy, attracted by the large number of works ordered. Many settled in Spain, such as Enrique de Arphe, Jacome Trezzo, Mateo Aleman, Hans Belta, and others. The Spaniards who joined them were greater in number, and not inferior in merit. Silversmiths were already at that time divided into different groups, according to the technical proceedings which each one adopted: _plateros de la plata_, workers in silver, was the name given to those who worked exclusively in _repoussé_ and chiselled work, and imitated sculpture and architectural models; goldsmiths, those who worked jewels with stones, enamels, and niello-work. Even within these groups were workers in filigree, and those who decorated different objects with painted or mosaic work, _atauxia_, in the Moorish style. Almost all the most important Spanish towns were large centres of these industries. Leon, Burgos, Valladolid, Cuenca, Toledo, Cordova, and Seville rivalled each other in the number and quality of their productions. The Venetian ambassador, Navagiero, who visited Valladolid in 1527, says, "Sono in Valladolid assai artefici di ogni sorte, e se vi lavora benissimo di tutti le arti, e sopra tutto d' argenti, e vi son tanti argenten quanti non sono in due altri terre, le prime di Spagna" ("Il Viaggio di Spagna," Vinegia, 1563, p. 35.) In order to complete the study of this subject, it is necessary, besides, to give some notice of the legal dispositions contained in the Municipal Ordinances and in other laws of a more general character. In Capmany's "Memorias," vol. i., part 3, p. 88, are to be found several statutes concerning the silversmiths of Barcelona from the 14th century, proving the importance of this guild in 1301. At this period three of its members formed part of the town Council. The introduction of a statute of 1489 proves the excellence of the works which they made. "Experience having shown us in past times, and proof existing at the present time, that such clever silversmiths have existed and exist at Barcelona that their works are highly reputed by kings and great people, and held in great honour and estimation in the town itself." The Silversmiths' guild still preserve the folio volumes full of drawings, and the description of the different objects which they presented for the approbation of the jury, during the 16th and 17th centuries. The designs contained in these volumes constitute a most interesting collection of jewels, giving a good idea of the great height of this industry in Barcelona. Baron C. H. Davillier is about to publish a volume on Spanish silversmiths, in which etchings of several of these designs will be reproduced. In the list of artists which follows I give the names of the most remarkable of those who worked at Barcelona.
