There is no triforium, but a finely carved late Gothic balcony runs around the nave and transepts below the clerestory. In the transepts, this is surmounted by a second one underneath the small roses which penetrate their upper wall surfaces. Both nave and side aisles are lofty, the vaulting rising in the former to a height of about 100 feet and, in the latter, to 80 feet, while the cupola soars 330 feet above. The vaulting itself is most elaborate and developed. While the early Gothic edifices have only the requisite functional transverse, diagonal and wall ribs, we now find every vault covered with intermediate ones of most intricate designs. Especially over the Capilla Mayor in its ambulatory chapels and around the lantern, this ornamentation becomes profuse,--everywhere ribs are met by bosses and roses. The general effect of the endless cutting up of the vaults into numberless compartments by the complicated system of lierne ribs is one of restlessness. One misses the logical simplicity of the thirteenth and fourteenth centuries and is reminded of the decadent surfacing of late German work and the ogee, lierne ribs of some of the late English, in which the true ridges can no longer be distinguished from the false. Looking up into the dome over the crossing, we see that the pendentives do not rise directly above the four arches, but spring some fifteen feet higher up above a Gothic balustrade which is surmounted by elliptical arches pierced by circular windows. The dome, disembarrassed of the ribs which still cling to some of its predecessors, is finely shaped,--a thorough Renaissance piece of work. Light streams down through the bull's eye under the lantern. There is considerable difference in the design as well as workmanship ofthe many rejas. Tremendous iron rails, surely not as fine as those of Seville, Granada, or Toledo, but still very remarkable, close the three sides of the Capilla Mayor and the front of the choir. The emblematical lilies of the Cathedral rise in rows one beside the other, as one sees them in a florist's Easter windows. Rejas close off similarly all the outer chapels from the side aisles. Among the very few portions of the old Cathedral which remained intact after the fury of the Comunidades, were the choir stalls and an exquisite door. The former were placed in the new choir and the latter became an entrance to the transplanted cloisters. It was indeed fortunate that these stalls were spared, for they are among the most exquisite in Spain and excelled by few in either France or Germany.
