The ‘Panteon de los Reyes’, the royal sepulchre, was finished in 1654. It was intended that it should be severely plain; but after the time of Philip II., those who continued the work, indulged their fancy for gilt decoration. A portrait of Father Nicolas is seen as we enter the staircase of the vaults; and after descending about a score of steps, we reach the Panteon de las Infantas and the Panteon de los Infantes, where rest the remains of the two sisters of Charles V., Don John of Austria, and other royal persons. This part of the royal vaults is not of especial interest architecturally, and a more adequate place of sepulture is now being constructed. The doorway of the vaults is of marble and bronze, and there is a tablet with the following inscription: ‘To the very good and very great God; sacred spot dedicated by the piety of the Austrian dynasty to the mortal remains of the Catholic kings, who await the desired day under the high altar consecrated to the Redeemer of the human race. Charles V., most glorious of the emperors, resolved this place to be the last bed of himself and his lineage; Philip II., the wisest of kings, designed it; Philip III., a monarch sincerely pious, continued the work; Philip IV., great for his clemency, his constancy, and his devotion, augmented, adorned, and terminated it in the year of the Lord 1654.’ The figures of Italian bronze near the tablet, symbolise Humanity and Hope. From this point the descent to the tombs is made upon steps of marble, with three landings, until an octagonal chamber is reached. A great candelabrum of bronze hangs here, and there are relief figures of the Apostles. The decorations of this vault of jasper and marble were executed by Fanelli. The materials used for the altar in this chamber are black marble and bronze. Two lay-brothers of the Escorial made the bronze Entombment of Christ. In the niches rest twenty-six urnas containing the ashes of Spanish sovereigns. The kings are Charles V., Philip II., Philip III., Philip IV., Charles II., Luis I., Charles III., Charles IV., and Ferdinand VII. On the left of the altar are the remains of Isabella, wife of the Emperor Charles, Anne of Austria, Margaret, Isabel of Bourbon, Mary Anne of Austria, Maria of Savoy, Maria of Saxony, and Maria Luisa of Bourbon. Ferdinand VII. used to attend Mass at midnight in this damp, chilling, and sombre sanctuary, where rest the bones of so many of his ancestors.
