is known as the Livre d'Artus (Book of Arthur). Prose Lancelot The Lancelot en prose, also known the Estoire de Lancelot (Story of Lancelot), follows the adventures of the eponymous hero Lancelot as well as many other Knights of the Round Table during the later years of King Arthur's reign until its end following the Grail Quest. The Lancelot–Queste–Mort Artu trilogy is made of three main sections, of which tone the first (composed c. 1215–1220) can be characterized as colorful, the second (c. 1220–1225) as pious, and the third (c. 1225–1230) as sober: The Vulgate Lancelot propre (Lancelot Proper), also known as the Roman de Lancelot (Novel of Lancelot) or just Lancelot du Lac, is the longest part, making up fully half of the entire cycle. It is inspired by and in part based on Chrétien's poem Lancelot, le Chevalier de la Charrette (Lancelot, or the Knight of the Cart). It primarily deals with a series of episodes of the early life of Lancelot and the courtly love between him and Queen Guinevere, as well as his deep friendship with Galehaut, interlaced with the adventures of Gawain and other knights such as Yvain, Hector, Lionel, and Bors. The actual [Conte de la] Charrette ("[Tale of the] Cart"), an incorporation of a prose version of Chrétien's poem, spans only a small part of the Vulgate Lancelot. Due to its length, modern scholars often divide the Lancelot into various sub-sections, including the Galehaut, further split between the Charrette and its follow-up the Suite de la Charette (Continuation of the Charrette); the Agravain (named after Gawain's brother Agravain); and the Preparation for the Quest linking the previous ones. The Vulgate Queste del Saint Graal (Quest for the Holy Grail), or just the Vulgate Queste, is another highly religious part of the cycle. It relates how the Grail Quest is undertaken by various knights including Perceval and Bors, and achieved by Lancelot's son Galahad, who here replaces both Lancelot and Perceval as the chosen hero. It is purported to be narrated by Bors, the witness of these events after the deaths of Galahad and Perceval. The Vulgate Mort le roi Artu (Death of King Arthur), or just the Vulgate Mort Artu / La Mort Artu, a tragic account of further wars culminating in the king and his illegitimate son Mordred killing each other. The ruin of Arthur's kingdom is here presented as the disastrous
