Soon after the fall of the Caliphate, metallic-lustred ware was made in Spain: Edrisi, the most remarkable Arabic geographer of the Middle Ages, in describing Calatayud, says: "Here the gold-coloured pottery is made which is exported to all countries." ("Descrip. de l'Afrique et de l'Espagne," Leyde, 1866.) Edrisi was born in the year 1100. He studied at Cordova, and finished writing his book in 1154. The circumstance of this pottery being mentioned in the 12th century as excellent enough for exportation, certainly makes it appear probable that the _fabrique_ already existed at an earlier date, especially when we bear in mind that Calatayud was conquered in the year 1120 by the Christians, and it is impossible to suppose that they established an Oriental industry there which was foreign to their culture, or to the contemporary Christian art. This text of Edrisi's has hitherto not been properly interpreted. In Jauber's translation (Edrisi, Paris, 1836-40), he interprets the word _guidar_, [Illustration: Arabic], _lutum purum_ of potters, as the name of a gilt textile, perhaps because in his time it was difficult to believe in the existence of metallic-lustred pottery. In the Edit. of Leyden, by Messrs. Dozy and Goeje, the sense of the word is properly given; indeed, Jauber himself translates it by _porcelain_ in the chapter of this volume which refers to China. This text of Edrisi's has never yet been quoted by writers on Ceramic Art; but once known it is impossible for a moment to state that the earliest manufacture of Moorish lustred ware was that at Malaga, an opinion which has been supported hitherto on the quotation from Ben Batutah's works, which will be given later on. I regret to have found no other allusion to the lustred ware of Aragon until the 10th century. No mention is made of it in the geographical texts published by Juynboll, Al Makkari, or other Arabic writers. From what we know of Aragon in the 16th century, it was a great centre of this industry, and its productions rivalled those of Valencia and Andalucia. The next text which alludes to this manufacture is given by Ben Batutah, a celebrated traveller, who, after travelling for twenty years in the East, went from Tangiers to Granada, from 1349 to 1351. Passing by Malaga, he says: "At Malaga, the fine golden pottery is made which is exported to the furthermost countries." ("Voy. d'Ibn Batoutah," Paris, 1853-58, vol. iv. p. 367.) This text has been constantly reproduced and commented upon, since Baron Charles Davillier first drew attention to it in his interesting little _brochure_ on "Faïences Hispano-Moresques."
