Chrétien de Troyes was a 12th-century French poet and writer, known for his contributions to the Arthurian legend. He is often credited with popularizing the tales of King Arthur and the Knights of the Round Table, introducing key characters like Lancelot and Graal. His works, including "Erec and Enide," "Cligès," and "Perceval," blend romance, adventure, and chivalric ideals. Chrétien's storytelling style and themes of love and honor significantly influenced later medieval literature and established the foundation for future Arthurian narratives.
