Francesco deli Organi (1325?-Florence, 1397)  is the famous blind  musician  who created the  sixth cadence. Best known as Francesco Landini, he is the bigger exponent of italian Ars Nova. Francesco appears lovely described by Giovanni Gherardi da Prato in the “Paradiso degli Alberti” . He is celebrated as Dante and much better than Petrarch by Jacopo da Pecora in the “Fimerodia” . His contemporary florentine historian Filippo Villani says that he received de “Corona Laurea” for poetry in Venice by Peter I of Cyprus. In the miniature of the Squarcialupi Codex, he appears laurel crowned with the lamenting Music is at the bottom of the page. The crowing event probably occurred in juin 1364, during the celebrations of victory on Candia rebels; but the great Petrarch, who was in Venice at that time, never speaks about him in his letters. This is the reason because most italian humanists usually minimize the success of the musician and ignore him in the history of italian literature. The book shows  that the famous Magister was also a poet who inspired Petrarch, and that the “Canzoniere”, describes his portrait. Anna Chiappinelli  proves that Landini was already active during the first generation of Ars Nova composers, and should have met Petrarch in the early Thirteen-Fifty. This is evident by the surprising sequential coincidences between the texts of Landini’s songs, and the various editions of the “Canzoniere” (started from 1350 up to the 1374 Vatican edition). As a consequence, the real “Laura” was a singer surnamed “Luce”, who was probably imprisoned and died in 1365. After that date, Francesco Landini came back to Florence and became a priest.
