What is the historical importance of Chrétien de Troyes' work Yvain, the Knight of the Lion?
Explanation
Chrétien de Troyes' Yvain is notable because it reshaped the story of King Arthur into the romance genre, blending chivalric adventure with romantic themes. While other elements like the Knights of the Round Table and courtly love appear in Arthurian literature, Chrétien's key contribution was this narrative transformation.
