While in England we were struggling with the difficulties of adapting medieval forms of libraries and bookcases to the ever-increasing number of volumes, a new system was initiated on the continent, which I propose to call the wall-system.

Fig. 118. Bookcases in the Library of the Escõrial on an enlarged scale.

It seems so natural to us to set our bookshelves against a wall instead of at right angles to it, that it is difficult to realize that there was a time when such an arrangement was an innovation. Such however was the case. I believe that this principle was first introduced into a library at the Escõrial, which Philip the Second of Spain began in 1563, and completed 13 September, 1584. I do not mean by this sentence that nobody ever set bookshelves against a wall before the third quarter of the sixteenth century. I have shewn above, when discussing the catalogue of Dover Priory[494], that the books stood on pieces of furniture which were probably so treated; and it is not uncommon in illuminated manuscripts to see a writer's books standing on one or more shelves set against the wall near his desk. Further, in the accounts of the library arranged in the Vatican by Sixtus IV., shelves set against the wall of one of the four rooms are specially mentioned[495]; and in the description of the library of the Dukes of Urbino, it is expressly stated that "the shelves for the books are set against the walls (le scanzie de' libri sono accostate alle mura)[496]." What I wish to enforce is that before the Escõrial was built, no important library was fitted up in that manner from the beginning by the architect.

The library of the Escõrial[497] occupies a commanding position over the portico through which the building is entered. It is 212 ft. long, by 35 ft. broad and about 36 ft. high. The roof is a barrel-vault, gorgeously painted in fresco, as are the wall-spaces above the bookcases, and the semicircular lunettes at the ends of the room. In that at the north end is Philosophy, in that at the south end is Theology, while between them are personifications of Grammar, Rhetoric, Logic, Music, etc. On the walls, forming a gigantic frieze, are various historical scenes, and figures of celebrated persons real and imaginary, as for instance, the first Nicene Council, the School of Athens, Solomon and the Queen of Sheba, Cicero, David, Orpheus, etc. The general appearance of this splendid room will be understood from the view ([fig. 117]). It is lighted by five windows on the east side and seven on the west side, to which is added on the east side a range of five smaller windows just under the vault. The principal windows are quite different from those of any other library I have been considering, for they are nearly 13 ft. high, and extend down to the floor.

The wall-spaces between each pair of windows have bookcases fitted to them, of a very original and striking design. They are divided into compartments by fluted Doric columns supporting an entablature with projecting cornice, above which again is a sort of second entablature. The bases of the columns rest upon an extremely lofty plinth, intersected, at about three-quarters of its height from the ground, by a shelf, behind which is a sloping desk. The material used for these cases is mahogany, inlaid with ebony, cedar, and other woods. They were designed by Juan de Herrera, the architect of the building, in 1584, and I am assured that they have escaped alteration, or serious damage from the numerous fires which have occurred in the palace.
