Cligès
Cligès is a poem by the medieval French poet Chrétien de Troyes, dating from around 1176. It is the second of five Arthurian Romances; Erec and Enide, Cligès, Yvain, Lancelot and Perceval. The poem tells the story of the knight Cligès and his love for his uncle's wife, Fenice. Because of the story's de-romanticized depiction of adultery, it has been called a criticism or parody of the Tristan and Isolde romances .
