and by red and white birds. I do not think that any existing example of this green enamelled glass could be safely referred to an earlier date than the end of the fifteenth century. But it is not improbable that the Catalans learned the use of these enamels not from the Venetians, but directly from Saracenic or Jewish glass-workers in some of the ports of the Levant. Such a distant source for this decoration, which is indeed somewhat Oriental in character, I think more probable than a local one in Spain, for we have no evidence that the Moors, when they held the Peninsula, ever practised the art of enamelling glass, nor indeed were the Catalans, after very early times, ever brought much into contact with their Mohammedan neighbours: their main dealings were with the Levant. That the glass of Barcelona was widely known and held in some repute before the end of the fifteenth century, the following notices go far to prove. As early as 1491—so it is stated in a contemporary Latin manuscript—glass vessels of various shapes, resembling those made at Venice, were exported to Rome from Barcelona. Again, when Philippe le Beau passed through the latter town in 1503, we are told that he went ‘_en dehors de la ville veoire ung four ou faict voires de cristallin très beaus_’ (Schuermans, _Bulletin_ xxix. p. 138 _seq._). Finally, Ferdinand of Aragon, about the same time, is reported to have sent to Queen Isabella a present of 274 pieces of glass manufactured in Barcelona. That this glass must have been possessed of some artistic merit we may infer from the fact that the Queen presented several pieces to the Capella de los Reyes at Granada. These we may perhaps identify with the _vasi di vedro_ seen among the treasures of this chapel a few years later by the Venetian ambassador (Andrea Navagero, _Viaggio in Spagna et in Francia_). M. Gerspach, I may add, calls attention to an inventory drawn up during the reign of Philip II., in which, under the heading of _bidrios de Barcelona_, 119 pieces of glass of various forms are catalogued; among other things—and this is a point of great interest—mention is made of some enamelled lamps.
