_The Sacristía Mayor_ is in the Renaissance style. It was built by the designers of the Sacristía de los Cálices about the year 1532. Campaña's admirable Descent from the Cross is here, but the picture has been indifferently restored. There is also a work of Murillo, SS. Leandro and Isidoro. The Cathedral Treasury is in this sacristy. One of the principal objects of interest is the splendid _custodia_, used for carrying the Host. It is the work of Juan d'Arphe, a celebrated gold-worker, who was born in Avila in 1535. In 1564 he constructed the _custodia_ of that city, and in 1580 began a work of a similar character for Seville Cathedral. Many designs were submitted for the inspection of the Chapter, but Juan d'Arphe's was chosen as one unequalled in Spain. The _custodia_ is about twelve feet high, round in form, with four storeys, each one supported by twenty-four columns. Some of the columns are Ionic; the rest are Corinthian and composite in design. Between the columns are a number of statuettes, and the base and cornices are profusely adorned with bas-reliefs. In the first storey there was originally seated a figure of Faith, but it was changed in 1668 for one of the Virgin of the Conception, when the _custodia_ was restored by Juan Segura. The second storey is the repository of the Host, and in the third and fourth storeys are figures of the Church Triumphant and the Holy Trinity. Crowning the edifice was a small dome and cross, which was replaced in 1668 by a statue of the Faith. The _custodia_ is of beautiful and simple design. The _Tablas Alfonsinas_, a reliquary, given to the Church in 1274 by Alfonso el Sabio, are in the Treasury. Crosses, plate and sacerdotal vestments are among the treasures. The canonical robes date from the fourteenth century. The keys of Seville, yielded to Fernando el Santo on the day of conquest, are also shown here. _The Capilla del Mariscal_ adjoins the Sacristía Mayor. In this chapel is the great altar-piece of Pedro Campaña, restored in 1880. The work is in ten parts, representing scenes in the life of Christ, and containing portraits of Marshal Pedro Caballero and his family. _The Sala Capitular_ was the work of Riaño and Gainza. It was begun in 1530 and finished in 1582. The plateresque decorations are very beautiful. Note the fine ceiling, the marble medallions, and the pavement. Murillo's Conception is here, and the Four Virtues of Pablo de Céspedes. There is a picture of San Fernando by Pacheco, the father-in-law and instructor of Velazquez. The ovals between the windows were the work of Murillo. This _sala_ is close to the Puerta de los Campanillas, and beyond this entrance, on the east side of the Cathedral, is _The Capilla de la Concepción Grande_, containing a monument to Cardinal Cienfuego, a modern work. The other small chapel on this side is that known as
