Answer the following question: Read the following paragraph and extract the answer for the question: What are the two names for the Middle French prose work that made up half of the entire Lancelot-Grail Cycle?  Up to c. 1210, continental Arthurian romance was expressed primarily through poetry; after this date the tales began to be told in prose. The most significant of these 13th-century prose romances was the Vulgate Cycle (also known as the Lancelot-Grail Cycle), a series of five Middle French prose works written in the first half of that century. These works were the Estoire del Saint Grail, the Estoire de Merlin, the Lancelot propre (or Prose Lancelot, which made up half the entire Vulgate Cycle on its own), the Queste del Saint Graal and the Mort Artu, which combine to form the first coherent version of the entire Arthurian legend. The cycle continued the trend towards reducing the role played by Arthur in his own legend, partly through the introduction of the character of Galahad and an expansion of the role of Merlin. It also made Mordred the result of an incestuous relationship between Arthur and his sister Morgause and established the role of Camelot, first mentioned in passing in Chrétien's Lancelot, as Arthur's primary court. This series of texts was quickly followed by the Post-Vulgate Cycle (c. 1230–40), of which the Suite du Merlin is a part, which greatly reduced the importance of Lancelot's affair with Guinevere but continued to sideline Arthur, and to focus more on the Grail quest. As such, Arthur became even more of a relatively minor character in these French prose romances; in the Vulgate itself he only figures significantly in the Estoire de Merlin and the Mort Artu. During this period, Arthur was made one of the Nine Worthies, a group of three pagan, three Jewish and three Christian exemplars of chivalry. The Worthies were first listed in Jacques de Longuyon's Voeux du Paon in 1312, and subsequently became a common subject in literature and art.
