According to the Prologue, one knows a play is good if it seems new or fresh despite being performed or seen many times. A good play doesn’t seem stale or monotonous just because one has seen it before: the Prologue’s implication is that such a play is like a new bride who still appears fresh, youthful, and enticing, despite no longer being a virgin. The Prologue's comparison is sexist and insinuates that women are less appealing and valuable once they lose their "honor" or virginity. However, Shakespeare and Fletcher's contemporary audience wouldn't have taken issue with this, even if it's somewhat troubling to a contemporary audience. This passage is also important because it explains that the play is based on a work by Chaucer ("The Knight's Tale" from
The Canterbury Tales). That the playwrights turned to Chaucer for inspiration implicitly emphasizes the theme of honor: the play is the playwrights' way of honoring the great Chaucer, whom they regard as one of the most "learned" and "famous" poets of all time.
