The wealthy scholars and merchant princes of Florence, whose collections of manuscripts were given to the city during their lifetime, or who left such collections after their death to the Florentine libraries, made it, as a rule, a condition of such gifts and such bequests that the books should be placed freely at the disposal of visitors desiring to make transcripts of the same. Such a condition appears in the will of Bonaccorsi,[334] while a similar condition was quoted by Poggio[335] in his funeral oration upon Niccolo d’ Niccoli, as having been the intention of Niccolo for the books bequeathed by him to his Florentine fellow-citizens. Foreign collectors who did not find it convenient themselves to visit Florence, such as the Duke of Burgundy, and Matthias Corvinus of Hungary, kept employed in the city for a number of years scribes engaged in the work of preparing copies of these Florentine literary treasures for the libraries of Nancy and of Buda-Pesth. Matthias was, it seems, not content with ordering the transcripts of the works desired by him, but employed a scholarly editor, resident in Florence, to supervise the work and to collate the transcripts with the originals, and who certified to the correctness of the copies forwarded to Buda.[336] At the death of Matthias, there appear to have been left in Florence a number of codices ordered by him which had not yet been paid for, and these were taken over by the Medici.[337] In a parchment manuscript of the Philippian orations is inscribed a note by a previous owner, a certain Dominicus Venetus, to the effect that he had bought the same in Rome from a Florentine bookseller for five ducats in gold in 1460.[338] Dominicus goes on to say that he had used this manuscript in connection with the lectures of the learned Brother Patrus Thomasius. During the thirteenth century, there was a considerable development in the art of preparing and of illuminating and illustrating manuscripts. One author is quoted by Tiraboschi as saying that the work on a manuscript now required the services not of a scribe, but of an artist. For the transcribing of a missal and illuminating the same with original designs, a monk in Bologna is quoted as having received in 1260 two hundred florins gold, the equivalent of about one hundred dollars. For copying the text of the Bible, without designs, another scribe received in the same year eighty lire, about sixteen dollars.[339]
