How is it possible, after four centuries, that a major episode in Rabelais's novels remains systematically misread? The episode, which playfully and grotesquely treats the relation of Carnival to Lent, occurs in Rabelais's Fourth Book, his last and most artfully crafted novel. Samuel Kinser argues that the text has been distorted because critics have not attended to the episode's performative as well as literary contexts, overlooking the innovative use Rabelais made in his work of his immediate world. In this original interpretation of the Fourth Book, Kinser evokes the gestures, games, and visual, oral, bodily semantics of Carnival and Lent as they were performed in Rabelais's day. He also underscores the importance to Rabelais of the invention of printing, an innovation which revolutionized the relationships of author and reader. Understanding this and fearing it, Rabelais adopted an extraordinary set of disguises as an author, disguises which in their bewildering interplay constitute the truest sense of his carnival.
