Metafictional

Metafiction is a narrative technique or genre of fiction characterized by a fictional work (a novel, film, play, etc.) that self-consciously draws attention to its own status as a work of imagination, rather than reality. Metafiction poses questions about the relationship between fiction and reality, usually using irony and self-reflection. It can be compared to presentational theatre, which does not let the audience forget it is viewing a play; metafiction forces readers to be aware that they are reading a fictional work.

Metafiction is primarily associated with late modernist and postmodernist literature, but is found at least as early as Homer's Odyssey, Chaucer's 14th century Canterbury Tales, and Laurence Sterne's Tristram Shandy (1756). Cervantes' Don Quixote, published in the 17th century, is a metafictional novel and so is James Hogg's The Private Memoirs and Confessions of a Justified Sinner published in 1824. Russian author Nikolai Gogol implements a limited, self-referencing narrator in his novel, Dead Souls published in 1842. The novels of Brian O'Nolan, written under the nom de plume Flann O'Brien, are considered to be examples of metafiction. In the 1950s several French novelists published works whose styles were collectively dubbed "nouveau roman". These "new novels" were characterized by the bending of genre and style and often included elements of metafiction. It became prominent in the 1960s, with authors and works such as John Barth's Lost in the Funhouse, Robert Coover's "The Babysitter" and "The Magic Poker", Kurt Vonnegut's Slaughterhouse-Five,John Fowles' The French Lieutenant's Woman, Thomas Pynchon's The Crying of Lot 49 and William H. Gass's Willie Master's Lonesome Wife. William H. Gass coined the term "metafiction" in a 1970 essay entitled "Philosophy and the Form of Fiction". Unlike the antinovel, or anti-fiction, metafiction is specifically fiction about fiction, i.e. fiction which deliberately reflects upon itself.
