Non-fiction, this volume—Il Quattrocento e l’Ariosto—is the third entry in a broader series on the History of Italian Literature. It examines the literary evolution from the 15th century to the early 16th century, focusing on humanism, courtly culture, and the emergence of the Renaissance epic. Central attention is given to Ludovico Ariosto, contextualizing Orlando Furioso within classical revival and vernacular experimentation. The 1966 first edition provides a scholarly yet accessible synthesis, aimed at students and readers interested in Italian Renaissance literature and its canonical authors.
