The cathedral is a magnificent building, the largest in Spain, and greater than St Paul's in London. Gautier said that "Notre Dame de Paris might walk erect in the middle nave." There are seven naves with monstrous columns, the loftiness of the interior conveying a sense of vastness which has been often described by travellers. More than a hundred years were spent in the building of this great church, and several architects planned the various parts during that period. Ruiz and Rodriguez designed the greater portion, and the last of the architects was Juan Gil de Houtañon, who planned the cathedral of Salamanca. The chief front is finely decorated, and has three portals, with statue groups and reliefs. There is so much of beauty and interest in the interior that I can only write briefly of a few of the most notable objects. The stained windows number over seventy, and they are chiefly by Aleman, a German, and by Flemish artists of the sixteenth century. The choir altar has pictures, and a handsome plateresque screen. There are splendidly carved stalls, and a notable lectern. The sacristy is near the chief façade, with a high dome, several chapels, and some interesting statues. The retablo is by Roldan, a follower of Montañez. Murillo's "Vision of the Holy Child" is in the Capella del Bautisterio. In the Royal Chapel, which is interesting Renaissance work, richly ornamented, there are the tomb of Alfonso the Wise, and an old figure of the Virgin. Pedro Campaña's altarpiece, in the Capilla del Mariscal, should be seen. In the south transept is the noted "La Gamba," a painting by Luis de Vargas. The ornate Sala Capitular has the "Conception," by Murillo, and a painting by Pablo de Céspedes, who was a sculptor, poet, and painter, born at Cordova, and made a canon of the cathedral in that city. Céspedes was a fine portrait painter, and has been described as "one of the best colourists of Spain." The Sacristy de las Calices of the Capilla de Nuestra Senora de las Dolores contains Goya's well-known painting of Saints Justa and Rufina, the potter-girls who were martyred by the Romans. Here also will be seen a picture by Zurbaran; "The Trinity," by El Greco, the crucifix carved by Montañez, and a "Guardian Angel," by Murillo. The Capilla de Santiago has paintings by the early artists Valdés Leal and Juan de las Roelas.
