The plan of the chapel is an irregular hexagon. It should have been octagonal, but the western sides have not been carried through and end in a broad-armed vestibule, which by rights should be the radial chapel upon the extreme eastern axis of the whole church. Above the vaulting early German pendentives are inserted in the three faulty and five true angles in order to bring the plan into the octagonal vaulting form. The builder seems almost to have made himself difficulties that he might solve them by a tour-de-force. A huge star-fish closes the vault. The recumbent statues face an altar. The remaining sides are subdivided by typically Plateresque band-courses and immense coats-of-arms of the Haro and Mendoza families. The upper surfacing is broken by a clerestory with exquisite, old stained glass. It is melancholy to see tombs of such splendid execution crushed by meaningless, empty display, out of all scale, vulgar, gesticulating, and theatrical, especially so when one notices with what extraordinary mechanical skill much of the detail has been carved. It thrusts itself on your notice even up to the vaulting ribs, which the architect, not satisfied to have meet, actually crossed before they descend upon the capitals below.

Lacoste, Madrid CATHEDRAL OF BURGOS The Golden Staircase] The reja closing the chapel off from the apse is among the finest of the Renaissance, the masterpiece of Cristobal Andino, wrought in the year 1523. Curiously enough, the supporters of the shield above might have been modeled by Burne-Jones instead of the mediæval smith. The interior could not always have been as light and cheerful as at present, for probably all the windows were more or less filled with stained glass from the workshops of the many "vidrieros" for which Burgos was so renowned that even other cathedral cities awarded her the contracts for their glazing. The foreign masters of Burgos were accustomed to see their arches and sculpture mellowed and illumined by rainbow lights from above, and surely here too it was of primary importance. After the horrible powder explosion of 1813, when the French soldiers blew up the old fortress, making the whole city tremble and totter, the agonized servants of the church found the marble pavements strewn with the glorious sixteenth-century crystals that had been shattered above. They were religiously collected and, where possible, reinserted in new fields.
