 In the fields to the south and east of Carhaise, Arthur defends Leodegrance by defeating King Rience, which leads to his meeting and marriage with Guinevere.This version of the legend has Guinevere betrothed to Arthur early in his career, while he was garnering support.The following narrative is largely based on the Lancelot-Grail (Vulgate) prose cycle, telling the story of Lancelot and Guinevere in accordance to the courtly love conventions still popular in the early 13th-century France but soon afterwards directly condemned in the Post-Vulgate Cycle retelling that was a main source for Malory.
