The full name of this carpenter is known, from his receipts, to have been Francesco de Gyovane di Boxi da Milano. He received in all 300 ducats instead of the 130 mentioned in the first agreement, and when the last payment was made to him, 7 June, 1476, the following explanatory note is given: Moreover I have paid to the same [Francis the carpenter] 30 ducats for what remains due on 25 desks for the Library: for the longer ones, which are 10 in number, there were paid, as entered above, 130 ducats; for the rest there were paid 170 ducats, making a total of 300 ducats, and so he has been paid in full for all the desks, this 7th day of June, 1476[383]. In 1477 the furniture for the next room, the _Bibliotheca secreta_ or Inner Library, was begun. The work was entrusted to a Florentine, called in the Accounts merely _Magister Joanninus faber lignarius de Florentia_, but identified by M. Fabre with Giovannino dei Dolci, one of the builders of the Sistine chapel. The most important entry referring to him is the following: Master Giovannino, carpenter of Florence, had from me Platyna, librarian of His Holiness our Master, for making the desks in the inner library, for the great press, and the settle, in the said room--all of which were estimated by Master Francis of Milan at one hundred and eighty ducats--he had, as aforesaid, sixty-five ducats and sixty groats on the 7th May, 1477[384]. The last payment on this account was made 18 March, 1478, on which day he also received eight ducats for three frames "to contain the names of the books," and for some repairs to old desks[385]. These frames were painted by one of Melozzo da Forli's workmen[386]. In February, 1481, 12 book-chests were supplied[387]. The desks for the fourth room or _Bibliotheca pontificia_ were ordered in 1480-81. The workmen employed were Giovannino and his brother Marco. 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, L188 10_s._ 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 L33. 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 catenae innituntur_).
