Master Giovannino of Florence and Master Marco his brother, a carpenter, received xxv ducats in part payment for the desks which are being made in the library now added by His Holiness our Master, 18 July, 1480[388].

These workmen received 100 ducats up to 7 April, 1481, but the account was not then settled. Up to this period the bookcases had cost the large sum of 580 ducats or, if the value of the ducat be taken at six shillings and sixpence, £188 10s. of our money.

The purchase of chains began in January 1476[389]. It is worth notice that so simple an article as a chain for a book could not be bought in Rome, but had to be sent for from Milan; where, by the way, the dues exacted by the government made the purchase irksome and costly. The total number of chains bought was 1728, and the total cost 102 ducats, or rather more than £33. The rings were found to be too small, and were altered in Rome. Nothing is said about the place from which the rods came (ferramenta quibus catenæ innituntur).

In 1477 (14 April) "John the chain-maker (Joannes fabricator catenarum)" supplies "48 iron rods on which the books are strung on the seats[390]" and also 48 locks, evidently connected with the same number of rods supplied before. In the same year a key-maker (magister clavium) supplies 22 locks for the seats and cupboards in the Bibliotheca secreta[391]; and in 1480, when the Bibliotheca pontficia was being fitted up, keys, locks, chains, and other ironwork were supplied by Bernardino, nephew of John of Milan[392].

For further information we must turn to the catalogues. For my present purpose the first of these[393] is that by Platina, of which I have already spoken, dated 14 September, 1481. It is a small folio volume, written on vellum, with gilt edges, and in plain binding that may be original. The first page has a lovely border of an enlaced pattern with the arms of Sixtus IV. in a circle at the bottom.

The compiler of the catalogue goes through the library case by case, noting (at least in the Latin Library) the position of the case, the subjects of the books contained in it, and their titles. This is succeeded by an enumeration of the number of volumes, so as to shew, in a couple of pages, how many the whole Library contained. MM. Müntz and Fabre print this enumeration, but, so far as I know, the catalogue itself has not as yet been printed by any one. For my present purpose I shall combine the headings of the catalogue, the subjects, and the number of the volumes, as follows:

Before proceeding farther, it should be noticed that, on a rough average, each seat in the Latin Library, left hand, contained 47 volumes, and in the same Library, right hand, 43 volumes. In the Greek Library, each seat contained 50 volumes; in the Inner Library, 31 volumes; in the Bibliotheca pontificia, 21 volumes.
