It is almost impossible to classify the existing specimens of Hispano-Moresque pottery. A few examples are marked with the monogram of Manises, or possess some special sign, such as the Eagle of St. John, which would make it appear they were made in the province of Valencia, but as the texts from ancient authors only praise this pottery and give no details of its general characteristics, it is very difficult to assign any given specimens to the manufactories of Aragon and Valencia. The receipts which I have given prove that the ingredients used were the same, the modification in lustre was owing to the different combinations of silver and copper. The system hitherto adopted of classifying this ware by the localities in which it has been purchased is not a safe one, unless borne out by further evidence. All that can be done at the present time is to point out the oldest specimens, and probable period of their manufacture. As a general rule the finest specimens are also the oldest, for this industry decayed after the Moors were expelled from Spain, and Italian pottery was imported into that country in the 16th century. The opinion which has been so generally accepted that gold lustred pottery was made and exported from the Balearic Islands has been contradicted by D^{n}. Alvaro Campaner y Fuertes in a letter addressed to Baron Davillier which appeared in the "Museo Balear," Palma, 1875, in which he refutes the Baron's arguments on the pottery which he supposes to have come from that locality. TERRA COTTAS.--_AZULEJOS_, OR WALL DECORATIONS OF TILES.--EARTHENWARE.--BUCAROS AND UNGLAZED POTTERY. The earliest historical notice which I have met with of Terracottas is in a grant made in A.D. 1222, by King Don Fernando el Santo, in favour of the manufacturers of bricks or tiles at Talavera (M. S. Bibl. Nacional Madrid, Dd. 114, p. 17), and another document of a similar kind by his son, King Don Alonso el Sabio A.D. 1281, in favour of the Cathedral of Cordova, "that no pottery works should be allowed inside the town, unless they were established in the same manner as in the time of the Moors." (Mem. Hist. Español, t. ii. p. 45). Although this information is not of great importance, it enables us to infer that in the 13th century an industry existed in Spain which was closely connected with pottery. Baron Davillier mentions a privilege granted by King D^{n}. Jaime de Aragon to the inhabitants of Jativa, province of Valencia, in which he commands, "that any master potter who made jars, pots, pans, tiles, and bricks, should pay a tribute of one _besant_ yearly for each oven, and be permitted to carry out his industry with no other obligation or service." (Col. Doc. Ineditos, vol. xviii. p. 67.)
