Scholars agree that Chaucer's Troilus and Criseyde, a reworking of Boccaccio's Il Filostrato. has greater emotive force than its source. Chaucer's character portrayals underscore and enrich the Oedipal fantasy; thus an ordinary tale of a woman's infidelity has been transformed into a work that evokes the nuclear experience of betrayal by the Oedipal mother.
