This chapter discusses ways in which the Arthurian legend was transformed between the twelfth and fifteenth centuries by French and English romance writers, focusing on the introduction of new characters, changes to the roles of traditionally central characters, and conflicting loyalties and values. Arthur is often displaced from the central role in the plot and can seem passive and ineffective. Gawain is the Top Knight in the English tradition, but Lancelot (a French addition) becomes increasingly important, not least because of his long affair with the queen, which is a contributing factor to the final collapse of Camelot. Family matters increasingly lead to conflicts of loyalties: Morgan le Fay is hostile to her brother, Arthur, and his Orkney nephews grow in number, some loyal but some treacherous. Mordred is not only Arthur’s nephew but sometimes also his son by incest, destined to kill his father. The Grail quest features first Perceval and then Galahad (Lancelot’s illegitimate son); its spiritual values challenge the ethos of secular chivalry and ennobling love. Does this quest bring glory to Arthur’s Round Table, or is it a critique of a fatally flawed society? Important variations in medieval approaches to the legend appear through this period.

Focusing on the so-called “romances of adventure” (romans d’aventure) which made up the largest and most popular category of romances, this chapter provides representative glimpses of how complicated, and fluid, the presentation of gender is in romance. It primarily examines romances written in French because they were the earliest to be written and served as the model for most of those we find in other western European languages, as it explores how binaries such as passive/active and male/female were complicated by deliberate strategies on the part of authors (and patrons).
