According to Wikipedia: "Chrétien de Troyes (Old French Christian) was a French poet and trouvère who flourished in the late 12th century. Perhaps he named himself Christian of Troyes in contrast to the illustrious Rashi, also of Troyes. Little is known of his life, but he seems to have been from Troyes, or at least intimately connected with it, and between 1160 and 1172 he served at the court of his patroness Marie of France, Countess of Champagne, daughter of Eleanor of Aquitaine, perhaps as herald-at-arms (as Gaston Paris speculated). His work on Arthurian subjects represents some of the best regarded of medieval literature. His use of structure, particular in Yvain, the Knight of the Lion, has been seen as a step towards the modern novel."
