(4) _Cuenca_ tiles. Quantities of these, dating from the sixteenth and seventeenth centuries, may yet be seen in many parts of Seville; for instance, in her churches or her convents, in her superb Alcázar, or in the mansions of her old nobility. Probably the most remarkable of all are those in the gardens of the Alcázar, and lining the walls of the Pavilion of Charles the Fifth. The devices on these polychrome _azulejos_ (16th century; Plate liv.) are very numerous, including men and animals, centaurs and other monsters, the Pillars of Hercules, and imitations of elaborate dress fabrics. (5) _Pisano_ tiles. Although some facts have been unearthed concerning the Italian Francesco Niculoso Pisano, we do not know precisely in what year he came to Seville, or in what year he died. Davillier thought it probable that he had studied at Faenza or at Caffagiolo. At all events, it was Pisano who broadly launched the art of the Sevillian potters on the stream of the Renaissance.[70] I have stated that the tiles which bear his name are painted on a white or yellow ground. Consequently their surface is flat, without the ridges and depressions of the _cuenca_ or the _cuerda seca_ methods. We find _Pisano_ tiles applied to various objects, such as tombs, altars, friezes, and archivolts. This artist, says Gestoso, further introduced the use of two new colours,--violet and rose. Several of his best productions are still intact, including the doorway of the church of the monastery of Santa Paula (in which he was assisted by a Spanish master, Pedro Millan), and the altar of the Catholic Sovereigns in the Alcázar. Both these masterpieces were executed in the year 1504, and bear Pisano's signature. The doorway of Santa Paula is described by Gestoso as consisting of a single body of masonry, distinct from that of the building itself, though resting against it, and constructed of bricks of uniform size, which show us, by their perfect symmetry, how skilful were the masons of that time, with whom the Moorish craftsmanship was yet a living power. The doorway is formed by a series of concentric Gothic arches resting on slender pillars. The space which forms the outer archivolt is most remarkable. Upon a ground of _azulejos_ which copy the colour of the brickwork, we see a number of Plateresque designs of exquisite beauty, painted in white and blue, with occasional touches of other colours. Among the devices are chimeras, war-trophies, volutes, chaplets, parapegms, antelopes, masks, and others which are characteristic of the Florentine Renaissance. Upon this ground, and enclosed by circular garlands in high relief, consisting of polychrome fruits and flowers, are seven medallions containing figures of male and female saints, except the one which is upon the keystone, and which represents the birth of Christ. In this medallion the figures are enamelled in white upon a cobalt-blue ground, recalling, as also do the
