Final answer:
Sir William from 'A Knight's Tale' compares to The Knight from Chaucer's 'The Canterbury Tales' due to their honor and commitment to chivalry, despite Sir William's peasant background and the modern tones in the movie.
Step-by-step explanation:
The movie A Knight's Tale features Sir William, who can be compared to the knights found in Geoffrey Chaucer's The Canterbury Tales. The Knight from Chaucer's stories is the most likely comparison. Both characters exhibit honor, a commitment to chivalry, and prowess in tournaments, reflective of the chivalric code. However, Sir William's background as a peasant who pretends to be a noble to compete in tournaments is a significant departure from the Knight's noble lineage. Furthermore, A Knight's Tale incorporates modern attitudes and rock music, differing from the more serious tone of the medieval tales in The Canterbury Tales.
