"Doon" is an anonymous Breton lai that tells the story of a knight, Doon, who must pass certain tests to win the hand of a maiden. They marry; but he returns to France alone. He is later reunited with the lady thanks to their grown son, whom he recognizes after dueling him at a tournament. This lai is very similar to "Milun" by Marie de France. Composition and manuscripts "Doon"'s date of composition is estimated around the beginning of the 13th century. The lai is contained one existing manuscript: Paris, Bibliothèque Nationale de France, nouv. acq. fr. 1104, f. 15v, col. 1.

After only four days of marriage, however, Doon leaves his wife behind to return to France. He reveals to her that she is already pregnant and gives her a ring for her to give to the child.
