Gestoso says that the usual diameter of these plates is either twenty-three centimetres or forty-two centimetres. "Their decoration, betraying at a glance the Saracenic influence, consists of leaves and flowers, together with animals of a more or less fantastic character: lions, rabbits, and birds. In other specimens the centre is occupied by a heart, fleurs-de-lis, or other fancy devices, or yet, in some few cases, with the head of a man or woman. These central designs are surrounded with leaves and flowers. The draughtsmanship upon these plates is of the rudest, and the process of their colouring was as follows. The figures were drawn upon the unfired surface in manganese ink mixed with a greasy substance; and after this the aqueous enamel or glaze was allowed to drop from a hogshair brush into the spaces which the black had outlined." This will be recognized as the _cuerda seca_ process, so extensively employed in making Seville tiles. Nevertheless, judging by certain marks upon this pottery, Baron Davillier declared it to proceed from Puente del Arzobispo. The marks in question consist in one or two examples of what appears to be the letters A.P. or P.A.[91] Davillier, however, affirmed that he had seen a plate fully inscribed as follows:-- [Illustration] [91] These, says Señor Osma, are doubtful in every case, and are only found on plates which bear the figure of a lion. Two plates in this gentleman's possession are thus marked [Illustration], and another [Illustration].
