These rules differed slightly from those followed in France, where, with the exception of certain churches in the east, the windows of the thirteenth century were richer in decoration, more luscious in coloring and more harmonious in their tones than those of the fourteenth. There is little in this later century that can compare with the thirteenth-century series of Chartres figures.

The Leonese windows are perhaps loveliest late in the afternoon, when the saints and churchmen seem to be entering the church through their black-traceried portals, and, clad in heavenly raiment, about to descend to the pavement,—

As softly green,
As softly seen,
Through purest crystal gleaming,

there to people the aisles and keep vigil at the altars of God to the coming of another day.

There are, fortunately, scarcely any other colors or decorations,—or altars off side aisles,—that might divert the attention from the richness of glass. The various vaulting has the jointing of its stonework strongly marked, but, with the exception of the slightly gilded bosses, no color is applied. The glory of the glass is thus enhanced. Owing to the great portions of masonry which have been rebuilt, this varies in its tints, but the old was, and has remained, of such an exquisitely delicate creamy color that the new interposed stonework merely looks like a lighter, fresher shade of the old. The restoration has been executed with rare skill and artistic feeling.{110}

In studying the inner organism and structure of the edifice, one soon sees how recklessly the original fabric was constructed and in how many places it had to be rebuilt, strengthened and propped,—indeed, immediately after its completion. Here, as was the general custom in the greater early Gothic cathedrals, the building began with the choir and Capilla Mayor, to be followed by the transepts, the portions of the edifice essential to the service. The choir was probably temporarily roofed over and the nave and side aisles followed. The exterior façades, portals, and upper stories of the towers were carried out last of all by the aid of indulgences, contributions, alms and concessions.

In old manuscripts and documents which record the very first work on the cathedrals we find the one in charge called "Maestro,"—or magister operis, magister ecclesiae, magister fabricae, but not till the sixteenth century does the appellation "arquitecto" appear. His pay seems to have varied, both in amount and in form of emolument,—sometimes it was good hard cash, often a very poor or dubious remuneration, handed out consequently with a more lavish hand; sometimes grants, and again royal favor. Generally the architect entered into a stipulated agreement with the Cathedral Chapter, both as to his time and services, before he began his work. We find Master Jusquin (1450-69) receiving from the Chapter of Leon not only a daily salary but also annual donations of bushels of wheat, pairs of gloves, lodgings, poultry, other supplies, and the use of certain workmen.

Leon's unquestionable French parentage is, if possible,{111} even more obvious in the interior than in the exterior. The piers between nave and side aisles are cylindrical in plan, having in their lowest section on their front surface three columns grouped together that continue straight up through triforium and clerestory and carry the transverse and diagonal ribs of the nave. They have further one column on each side of the axis east and west and, strange to say, only one toward the side aisles, which thus lack continuous supports for their diagonal ribs. The outer walls of the side aisles are formed by a blind arcade of five arches, surmounted by a projecting balcony or corridor and a clerestory subdivided by its tracery into four arches and three cusped circles. The nave triforium consists of a double arcade with a gallery running between (one of the very rare examples in Spain). Each bay has in the triforium four open and two closed arches, surmounted by two quatrefoils. The clerestory rises above, divided by marvelously slender shafts into six compartments and three cusped circles in the apex of the arch. Here shine, in dazzling raiment and with ecstatic expressions, the saints and martyrs ordered in the fifteenth century from Burgos for the sum of 20,000 maravedis.

Throughout all the glazed wall surfaces we find evidence of the anxiety that overtook their reckless projectors. All but the upper cusps of the windows of the side aisles have been filled in by masonry, painted with saints and evangelists in place of the translucent ones originally placed here. The lower portions of the triforium lights have been blocked up and also the two outer arches of the clerestory. The light, clustered piers and slender, double flying{112} buttresses could not accomplish the gigantic task of supporting the great height above. Nor could the ingenious strengthening of the stone walls (consisting of ashlar inside and out, facing intermediate rubble) by iron clamps supply the requisite firmness.

It seems doubly unfortunate that the choir stalls should occupy the position they do here, when there is such liberal space in the three bays east of the crossing in front of the altar. The stone of their exterior backing is cold and gray beside the ochre warmth of the surrounding piers. The classic Plateresque statues and bas-reliefs, as well as the exquisitely carved, Florentine decoration, seems strangely out of place under the Gothic loveliness above. The trascoro itself is warmer in color, but of the extravagant later period. Its pilasters, spandrels, and band-courses are filled with elaborate and fine Florentine ornamentation, while the niches themselves, with high reliefs representing the Annunciation, the Nativity, and the Adoration of the Magi, are not quite free from a certain Gothic feeling. Above, great statues of Church Fathers weigh heavily on the delicate work and smaller scale below.
