The details concerning this industry in Cataluña are more interesting; especially on account of the references given to the marks of the objects proceeding from this manufacture. The potters, who were known by the generic name of _olleros_ sent, in 1257, two individuals to form part of the town council. They formed at that time a guild; in 1314 they agree in their regulations as to the mark to be adopted for their pottery, and the actual spot is mentioned on which every potter was to stamp his wares. This stamp was ordered to be very visible, and instructions are given as to the quality of the clay, and its manipulation, in order to produce pottery of a first-class order. We find statutes in this sense up to 1355. But we cannot find in the "Libro de Ordenanzas" of the potter's guild that any laws existed touching the technical details of this manufacture; most of the regulations refer to the management of the guild from 1304, which was composed of potters, bricklayers, jar-makers, and manufacturers of pottery for domestic purposes of Barcelona. (Capmany, Memorias Historicas, 1779-92, vol. i. part 3, p. 69.) [Illustration: WINE JAR--"TINAJA." SOUTH KENSINGTON MUSEUM.] These references are not, however, sufficient to identify the kind of pottery made at that time in Cataluña. It is highly probable that lustred ware was also made there to a great extent, not only because it was the most characteristic produce of the Peninsula, but also because this ware was exported to a great extent, and highly esteemed. The most important examples of Spanish terra-cotta which have reached us are _tinajas_, large jars for holding wine and oil. One of the best _tinajas_ which I know is at the South Kensington Museum, No. 330-'66. (See woodcut.) It is a wine jar, amphora-shaped, and ornamented with incised pattern of vine leaves, and stamped diaper of a Gothic character. This and similar specimens have always been found in Andalusia and the province of Toledo, and hence we may infer that the chief centres of this industry existed at Toledo and Seville. They continue to be made there, and are used for the same purposes as in the Middle Ages, for keeping stores of wine, oil, meat, grain, etc. Belonging to this section of objects of a large size, are some specimens of glazed earthenware made for brims of wells. I only know four or five examples in the local museums of Toledo and Cordova; the font of the church of San Salvador, Toledo, belongs also to the same pottery. The brim of a well, at the South Kensington Museum, No. 1763-'71, is of the same manufacture. It was bought at Toledo for three guineas at a shoemaker's shop. It is made of glazed white and green earthenware, with ornamental Cufic characters in high relief all round, which appear to be of the 14th century (see woodcut on next page). The inscription, which is repeated, is imperfect, and all that I can decipher are the words: [Illustration: Arabic "The power, the excellence, and the peace."]
