In British Sources of the Abduction and Grail Romances, Flint Johnson sets out to explore the possibility that familiar Arthurian stories, which have come down to us through Medieval romance, may contain relics of lost Welsh literary sources from the fifth or sixth century. Johnson bases his analysis on the most popular and influential works by the French author, Chr tien de Troyes, the tale of the abduction of Guenevere, (Le Chevalier de la Charrette) and the early Grail romance (Le Conte du Graal).
