Fie on a thousand pounds! This wide world...I would give it, if I were lord of it!
Dorigen promised Aurealis "in pley" that she would be his love if he could remove all the rocks from the side of the shore. Aurelius was left in sorrow, as he found the task impossible.
Aviragus is reunited with Dorigen as he had returned from abroad, and they are happy. Two years later, Aurelius was still tormented, but his brother, a clerk, suggested that he meet a student at law in New Orleans who knows how to make illusions.
Thus can a squire do a gentle deed as well as a knight...
Aurelius and his brother meet the student at law who shows him various tricks of illusion. Aurealis asks him if he can remove the rocks from the coast, which the student at law says he can do for one thousand pounds. Aurelius promised to pay later.
Aurelius comes to Dorigen to tell that he got rid of the rocks, much to her horror, as now she must either give herself up to Aurelius to fulfill her promise, or ruin her reputation. Dorigen contemplated suicide, but when Aviragus returns home and Dorigen tells him of the whole ordeal, Aviragus decides to bear the shame and allow Dorigen to go with Aurelius.
Aurelius learned how well the knight accepted the promise of the wife, and felt that he should not break the "trouthe" of the Aviragus and Dorigen's marriage. He releases Dorigen from keeping her promise, and lets her go back to Aviragus.
Aurelius realizes that he must pay the student at law for his services, but does not have enough money. He learns from Aurelius that he had to give up his love as to honor her marriage. The student at law, seeing that everyone acted nobly, cancels the debt that Aurelius owes.
