Per la biblioteca di Franchino Gaffurio: i manoscritti Laudensi

This article, within a study concerning the library of the theoretician and composer Franchino Gaffurio (1451-1522, Choirmaster of the Cathedral of Milan from 1484), presents two manuscripts preserved in the Biblioteca Comunale Laudense of Lodi: xxviii. A. 8 and xxviii. A. 9. The first one contains Bryennius, De harmonia, a translation commissioned by Franchino Gaffurio to Giovanni Francesco Burana: it’s an autograph manuscript of 1497. The second one contains Gaffurio’s De harmonia; it’s not an autograph, but it has been subjected to considerable revision by the author, who has intervened heavily in the text until 1514. The two manuscripts have been studied in relation to other Gaffurio’s manuscripts (some autographs), as witnesses of the various stages of the formation of theoretical thought of Gaffurio while he was in Milan, especially because at the same time Leonardo da Vinci, Luca Pacioli and Cesare Cesariano worked there.
