Through the courtesy of Señor Osma I am able to give illustrations of a few of the finest specimens of lustred ware in his magnificent collection (Plates lxii.-lxvi.). The three small vessels facing pages 176, 178, and 180 are of Valencian workmanship, and date, according to their owner, from between 1460 and 1480. The two plates are also Valencian. The one with a bull in the centre dates from between 1480 and 1500; and that which has a greyhound from slightly earlier--say 1470 to 1490. POTTERY OF SEVILLE, PUENTE DEL ARZOBISPO, TALAVERA DE LA REINA, TOLEDO, AND BARCELONA; POROUS WARE; PORCELAIN OF ALCORA AND THE ROYAL FACTORY OF THE BUEN RETIRO. We have seen that Seville was an early and important centre of the potter's craft in Spain. Her potteries were celebrated even with the Romans, and probably have at no moment been inactive. Fifty, established in the suburb of Triana, were mentioned in the sixteenth century by Pedro de Medina, and documents which tell of many more have recently been discovered by Gestoso. The excellence of the Seville tiles has been described in a preceding section of this chapter. Their production still continues upon a large scale; and the ware of the Cartuja factory, which reached the zenith of its fame towards the end of the eighteenth century, is considered by Jacquemart and other authorities to rival with the Italian wares of Savona. Pottery made in other parts of the Peninsula--particularly that of Talavera de la Reina--is known to have been imitated by the Seville potters with embarrassing perfection. In the case of the so-called "loza de Puente del Arzobispo," it is the Seville ware itself which seems to have been imitated. Puente del Arzobispo is a small village near Toledo. Mendez wrote of it in the seventeenth century:--"Fine pottery is manufactured in about eight kilns, which produce more than 40,000 ducats yearly." "In 1755," says Riaño, "thirteen pottery kilns existed at this place; they still worked in 1791, but their productions were very inferior in artistic merit." [Illustration: LXVII HISPANO-MORESQUE LUSTRED WARE] Not many years ago the name of Puente del Arzobispo was connected by Baron Davillier with certain polychrome non-lustred plates and other vessels which are greatly esteemed for their rarity, and of which a few specimens exist in the South Kensington and other museums, as well as in one or two private collections, such as that of Señor Osma.
