The arrangement of each room is not quite so simple as might appear at first sight; and, besides the desks, there are other pieces of furniture to be accounted for. We will therefore go through the rooms in order with the ground-plan ([fig. 98]). On this plan the cases are coloured gray, the readers' seats are indicated by transverse lines, and the intervals are left white.
Latin Library. The Accounts tell us that there were 10 seats on the left hand of the Latin Library, and that these were longer than the rest, measuring 38 palms each, or about 27 ft. 9 in. English[400].
As the distance from the central pier to the west wall is just 27 ft. 6 in., it is obvious that the cases must have stood north and south—an arrangement which is also convenient for readers, as the light would fall on them from the left hand. For this reason I have placed the first desk against the pier, the reader's seat being westward of it. A difficulty now arises. It is stated in the Accounts that ten banchi are paid for, but all the catalogues mention only nine. I suggest that the explanation is to be found in the fact that ten pieces of furniture do occur between the pier and the wall, the first of which is a shelf and desk, and the last a seat only. This arrangement is to be seen at Cesena and in the Medicean Library at Florence. The room being 34 ft. 8 in. wide, space is left for a passage along the south wall to the door (a) of the Librarian's room, and also for another along the opposite ends of the desks.
For the arrangement of the rest of the Library, the Accounts give a most important piece of information. They tell us that the whole of the seats for the Common Library, i.e. the Latin and Greek Libraries taken together, 25 in number, cost 300 ducats, of which sum the 10 long seats above mentioned absorbed 130 ducats, leaving 170 to pay for the remaining 15. From these data it is not difficult to calculate the cost of each palm, and from that the number of palms that 170 ducats would buy. I make this to be 510 palms, or about 373 feet[401].
It is, I think, obvious that there must have been some sort of vestibule just inside the door of entrance, where students could be received, and where they could consult the catalogue or the Librarian. Further, the catalogues shew that the seven desks arranged in this part of the Library were in all probability shorter than those of the opposite side, for they contained fewer volumes. If we allow each of them 21 ft. 4 in. in length, we shall dispose of 149 ft., which leaves 224 ft. for the 8 desks of the Greek Library, or 28 ft. for each, with one foot over.
Greek Library. In this room there were eight seats, and, as explained above, each was about 28 ft. long. The room being 28 ft. wide, this number, with a width of 3 ft. for each, is very convenient, and leaves a passage 4 ft. wide along the west wall. The length, moreover, does not interfere with the passage from door to door, and leaves a short interval between the ends of the desks and the opposite wall.
Inner Library. In this room space has to be provided for (1) six seats, each holding on an average about 30 volumes; (2) a press (armarium) with five divisions, and holding 938 volumes; (3) a settle (spalera); (4) 12 chests or coffers (capsæ).
I have placed the armarium at the end of the room, opposite the window. In this position it can be allowed to be 20 ft. in width with 5 divisions, each, we will suppose, about 4 ft. wide. Let us suppose further that it was 7 ft. high, and had 6 shelves. If we allow 8 volumes to each foot, each shelf would hold 32 volumes, and each division six times that number, or 192. This estimate for each division will give a total of 960 volumes for the five divisions, a number slightly in excess of that mentioned in Platina's catalogue.
After allowing a space 5 ft. wide in front of the press, there is plenty of room left for 6 desks, each 21 ft. long. I have placed the spalliera, with its four coffers (capsæ) under the seat, below the window. This piece of furniture, in modern Italian spalliera, French epaulière, is common in large houses at the present day. It usually stands in an ante-room or on a landing of one of the long staircases. A portion at least of the spalliere used in this Library are still in existence. They stood in the vestibule of the present Vatican Library until a short time ago, when the present Pope had them removed to the Appartamento Borgia, where they stand against the wall round one of the rooms. There are two distinct designs of different heights and ornamentation. The photograph here reproduced ([fig. 100]) was taken specially for my use. The spalliere have evidently been a good deal altered in the process of fitting up, and moreover, as it is impossible to discover whether we have the whole or only a part of what once existed, it is useless to make any suggestion, from the length of the portions that remain, as to which room they may once have fitted. They are excellent specimens of inlaid work. That on the right, with the row of crosses along the cornice, is 6 ft. 2 in. high, and 66 ft. long. That on the left is 5 ft. 10 in. high, and 24 ft. 7 in. long. The capsæ project from the wall 1 ft. 4 in., and are 2 ft. high. Their lids vary a little in length, from 3 ft. 11 in. to 4 ft. 10 in.
