The essay focuses on Gaspare Ambrogio’s first canzoniere, called Rithimi (1493), and analyses its textual history, its macrotextual structure and its relationship with other models. If Petrarch remains a beloved starting point, Visconti’s writings show contacts with many other authors, both ancient and modern, both Latin and vulgar, both on the microtextual and macrotextual level. A final comparison with the second canzoniere dedicated to Beatrice d’Este (ca. 1495-1496) allows to mark the difference between the two works of the author and specify the general characteristics of his lyrical production.
