Specimens of this work are in the British and Cluny Museums, and in the Archæological Museum at Madrid. An interesting jet figure of the apostle on horseback belonged to the late Count of Valencia de Don Juan. Jet processional crosses (twelfth and thirteenth century), studded with enamel, and which were used at funerals, are preserved in the cathedrals of Oviedo and Orense. Rings, rosaries, and amulets were also carved from this material. As to Spanish processional crosses generally (the use of which was undoubtedly borrowed from the standard borne at the head of pagan armies), I may say that they are commonly fitted with a handle, called the _cruz baja_ or "lower cross," though sometimes this handle is dispensed with, as, for instance, at the funerals of infants. According to Villa-amil y Castro, the typical shape of the Spanish processional cross has always been that denominated the _immissa_, consisting of four arms terminating in straight edges. The same authority says that within this broader definition the primitive form was the Greek cross, that is, having four arms of equal length. Another early form was the "Oviedo" cross (see Vol. I., Plate II.), with the four arms in the shape of trapezia, united at the centre by a disc. Of this latter shape are, or were, the crosses of Guarrazar and those which were presented by Alfonso the Second and Alfonso the Third to the cathedrals of Oviedo and Santiago. A later form was the _potenzada_ cross, which had a cross-piece fixed at the extremity of each arm. As time advanced, this T-shaped termination to the arms assumed such decorative and capricious forms as the trefoil and the fleur-de-lis. Early in the history of the Spanish church the processional cross consisted often of a wooden core, covered with more or less profusely ornamented silver plates, and having, between the handle and the upper part, an enamelled bulb or _n[oe]ud_. The image of Christ, converting the cross into the crucifix, was not attached until a later period, because, as Villa-amil y Castro has remarked, the primitive Christians considered the essential glory of their faith, rather than, as yet, the perils and the pains to which they were exposed by clinging to that faith. The cross was thus the symbol of the Christian's glory; the crucifix, of his suffering.[60]
