(2) A small group of curious tiles, believed to be anterior to the reign of Pedro the First, has come to light some years ago, in the churches of San Andrés and Santa Marina, and in the Claustro del Lagarto of the cathedral. Those of San Andrés are of white earthenware, glazed in the same colour and stamped from a mould with the figures of two wolves in fairly bold relief (see tailpiece to this chapter). Traces of a glaze of malachite green are on the bodies of these wolves. The _azulejos_ of the church of Santa Marina, also discovered recently, are examined by Señor Osma in his pamphlet _Azulejos sevillanos del siglo xiii_ (Madrid, 1902). They measure about three and a half inches square, and bear devices of a castle and an eagle, stamped in the diagonal direction of the tile, showing that this was fixed upon the wall in lozenge fashion. The tiles are bathed upon their surface with what is termed by Osma "the semi-transparent, caramel-coloured glaze peculiar to the pottery of Moorish Spain."[69] Upon this ground is stamped the decoration,--the eagles in the blackish purple of baked manganese, the castles without additional colour, so as to be distinguished only by their outline from the yellowish surface of the tile. [69] According to Gestoso, the colours in use among the Almohades consisted of green, black, caramel or honey, and deep purple. These colours underwent no change until the sixteenth century. The _azulejos_ of the Claustro del Lagarto of the cathedral are three in number, and were found in 1888. Two of them are stamped with a castle of a single tower described within a shield, and the third with a Greek cross. These are considered by Osma to be the only tiles existing at this moment which date from the latter third of the thirteenth century. In fact, he places their manufacture between the years 1252 and 1269. [Illustration: LIV _CUENCA_ TILES (_Alcázar of Seville_)] (3) _Cuerda seca_ tiles. Handsome _zocalos_ or dadoes of these tiles are in the Casa de los Pinelos, and in the chapels of the palaces of the Dukes of Alba and Medinaceli. Gestoso attributes them to the end of the fifteenth century or the beginning of the sixteenth. Detached _cuerda seca_ tiles are preserved in the municipal museum of archæology, while a fine pair (Plate liii.) of this class of _azulejos_ belongs to Señor Osma, who considers they were made between 1480 and 1495. They are thus coeval with the no less interesting dish of the time of Ferdinand and Isabella, of which a reproduction is given opposite page 190.
