Four Arthurian Romances: "Erec et Enide", "Cliges", "Yvain", and "Lancelot" by Chretien DeTroyes (Fl. 12th Century A.D.). Originally written in Old French, sometime in the second half of the 12th Century A.D., by the court poet Chretien DeTroyes.
Chrétien de Troyes' Four Arthurian Romances continued and expanded on existing Arthurian legends, but began the Arthurian Romance genre, so popular in Medieval literature. His tales often diverge from Arthur himself, focussing instead on the characters of his court. Chretien introduced Sir Lancelot and also the Holy Grail to the Arthurian legends. He is considered the first major French novelist.
Chrétien de Troyes (1135?–1185?, fl. c. 1160–1191) was a French poet and trouvère known for his writing on Arthurian subjects, and for first writing of Lancelot, Percival and the Holy Grail. Chrétien's works, including Erec and Enide, Lancelot, Perceval and Yvain, represent some of the best-regarded of medieval literature. His use of structure, particularly in Yvain, has been seen as a step towards the modern novel.
