"Chaitivel", also known as "Les Quatre Deuils" or "Le Malheureux" in modern French or "The Four Sorrows" in English, is a Breton lai by the medieval poet Marie de France. Chaitivel is the tenth poem in the collection known as the Lais of Marie de France and is one of very few lais to contain alternate titles. Like the other poems in this collection, Chaitivel is written in the Anglo-Norman dialect of Old French, in couplets of eight syllables in length.
