Not many other objects in this substance can be instanced as the work of Spanish craftsmen of the sixteenth and succeeding centuries, or of the later-Gothic age immediately preceding. Among them are the pulpits of Santiago cathedral, made by Celma, an Aragonese, in 1563; the choir-screen (1574-1579) in the cathedral of Zaragoza, made by Juan Tomás Cela, also a native of Aragon; the gilt lecterns of Toledo cathedral, which are the work of Nicolás Vergara and his son; the Gothic lectern of the mosque of Cordova; the choir-lectern (1557) of Cuenca, made by Hernando de Arenas, who will also be remembered as having made the _reja_ of the same cathedral; and the octagonal gilt-bronze pulpits of Toledo, wrought by Francisco de Villalpando, as are the bas-reliefs (1564) upon the door of Lions, executed by the same craftsman from designs by Berruguete. These last-named pulpits are associated with a legend. Within this temple, once upon a time, rested the metal sepulchre of the great Don Alvaro de Luna, so constructed by his orders that upon the touching of a secret spring the statue of the Constable himself would rise into a kneeling posture throughout the celebration of the mass. His lifelong and relentless foe, the Infante Enrique of Aragon, tore up the tomb in 1449; and from its fragments, superstition says, were made these pulpits. Spanish Renaissance door-knockers in bronze are often curious. Fifteen large bronze rings adorned with garlands, heads of lions and of eagles, or with the pair of columns and the motto PLUS OULTRE of Charles the Fifth, were formerly upon the pilasters of the roofless, semi-ruined palace of that emperor at Granada. Removed elsewhere for greater safety,[101] they will now be found among the couple of dozen curiosities preserved in a chamber of the Moorish royal residence of the Alhambra. [101] Spaniards have a very scanty confidence in one another's honesty, as well as in the competence of their police. Often, at Madrid, and at this day, the porter of a house, as soon as it is dark, unscrews the knockers from the downstairs door, and guards them in his _conciergerie_ until the morning.
