Answer:
The monk was sent by Count de Guiche to deliver a letter to Roxane telling her about his decision to stay back from the deployment for her sake.
Roxane tricked the monk into believing that she had been ordered by the Count to get married to Christian that instant and thus, led him into the house to officiate the marriage.
Explanation:
<em>Cyrano de Bergerac</em> is a play by Edmond Rostand that revolves around the love complications of Roxane with three different guys. One is her own cousin Cyrano, the second is the handsome nobleman Christian and the last being Count de Guiche. Roxane (Magdalene Robin), the women they are all wooing, loves Christian because of the letters she received from him, though in truth, it was written by her cousin Cyrano.
In scene 3 act X, the Capuchin monk had come to Roxane's home to deliver a letter from the Count to tell her about his stay behind even though his troops had gone for the war (which is not true).
The monk did not know the contents of the letter so Roxane pretended to read aloud the letter and told him that he had been sent to her place to officiate the marriage between Roxane and Christian, the man she loved deeply. The monk ended up marrying the two lovers which was never the motive of the letter.
