The romances were a new sort of literature featuring a new sort of hero, the “knight-errant,” a warrior who roamed the world in search of, precisely, “adventure”—in the contemporary sense of the word: perilous challenges, love, treasure, and renown. Stories of knightly adventure quickly became enormously popular, Chretein was followed by innumerable imitators, and the central characters in the stories—Arthur and Guinevere, Lancelot, Gawain, Percival, and the rest—became known to everyone, as they are still.
