have been much higher than this, I will quote the following curious rule, copied, as it would appear, in the Library itself, by Claude Bellièvre of Lyons, who visited Rome about 1513:
Nonnulla quæ collegi in bibliotheca Vaticani. Edictum S. D. N. Ne quis in bibliotheca cum altero contentiose loquatur et obstrepat, neve de loco ad locum iturus scamna transcendat et pedibus conterat, atque libros claudat et in locum percommode reponat. Ubique volet perlegerit. Secus qui faxit foras cum ignominia mittetur atque hujusce loci aditu deinceps arcebitur[1].
Another point is worth notice as bearing on the question of the style of desk used. At Cesena and at Florence the bar of iron along which the rings of the chains play, is under the edge of the desk; and the opposite end of the chain is fastened to the middle of the lower edge of the right hand board. I have examined a good many manuscripts now in the Vatican Library which formed part of the older collection; and wherever the mark of the chain has not been obliterated by rebinding, it is in the precise position required for the above system.
The arrangement of each room is not quite so simple as it 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. 2). On this plan the cases are coloured gray, the reader's 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[2].
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,
