 that when Chaucer (1343–1400) revised the love poem "Il Filostrato" by Giovanni Boccaccio (1313–1375) in his "Troilus and Criseyde" he medievalized it, using a medieval rhetoric and didactic style.For example, Chaucer made Troilus less of a “lady-killer,” to use Lewis’ phrase.That shows up both in Chaucer's writing of the story and in his telling of the erotic nature of the story.
