The door by which we entered is formed of bronze, and bears the following inscription: _Antonio Zurreno del arte de Oro y Plata, faciebat esta media puerta_. The impression produced upon the mind of the visitor is one of the most vivid and grandest description. The church is divided into five naves; the middle one being of the most unusual height, while the others beside it seem to bow their heads and kneel down to denote their respect and adoration. Eighty-eight pillars, each as large as a tower, and composed of sixteen spindle-shaped columns bound together, sustain the weight of this enormous edifice; a transept intersects the grand nave between the choir and the high altar, and forms the arms of the cross. The style of the entire building is most homogeneous and perfect, a kind of merit possessed by but few Gothic cathedrals, which have generally been erected piecemeal. The original plan has been strictly carried out from beginning to end, with the exception of a few arrangements in the chapels, which, however, do not in any way mar the harmony of the whole. Painted windows, glittering with the splendour of emeralds, sapphires, and rubies, and contained in stone nervures worked like so much silversmith's work, let in a mild and mysterious light which inspires you with deep religious feelings; when the sun is too fierce, spartum blinds let down over the windows diffuse throughout the building that cool half-state of obscurity which renders Spanish churches so favourable for meditation and prayer. The high altar or _retablo_ alone might be mistaken for a church. It is an enormous collection of small columns, niches, statues, foliage, and arabesques, of which the most minute description would convey but a very faint idea. All this mass of carving and ornaments, which extends completely up to the roof, is painted and gilt in the richest imaginable manner. The tawny, warm tones of the old gilding, cause the thin streaks and patches of light, which are caught in their passage by the nervures and projections of the ornaments, to stand out with splendid brightness, producing the most admirable, picturesque, and rich effect. The paintings, with their backgrounds of gold, which adorn the panels of the altar, equal in richness of colouring the most brilliant specimens of the Venetian school. This union of colour, with the severe and almost hieratic forms of mediæval art, is met with very rarely; some of these paintings might be taken for pictures in Giorgione's best style.
