Chrétien de Troyes was a 12th-century French poet known for his contributions to the Arthurian literary tradition. He is credited with popularizing the tales of King Arthur and the Knights of the Round Table, introducing characters like Lancelot and Perceval in his works. His narratives often blend romance, adventure, and chivalric ideals. His most famous works include "Erec and Enide," "Cligès," and "Perceval, the Story of the Grail." These stories not only entertained but also explored themes of love, honor, and the quest for identity. Chrétien's influence on medieval literature is profound, shaping the genre for future writers.
