Experimental literature is a genre of literature that is generally "difficult to define with any sort of precision." It experiments with the conventions of literature, including boundaries of genres and styles; for example, it can be written in the form of prose narratives or poetry, but the text may be set on the page in differing configurations than that of normal prose paragraphs or in the classical stanza form of verse. It may also incorporate art or photography. Furthermore, while experimental literature was traditionally handwritten, the digital age has seen an exponential use of writing experimental works with word processors.
Early history
The first text generally cited in this category is Laurence Sterne's The Life and Opinions of Tristram Shandy, Gentleman (1759). This text occurs so early in the standard history of the novel that one can't refer to its "breaking" conventions that had yet to solidify. But in its mockery of narrative, and its willingness to use such graphic elements as an all-black page to mourn the death of a character, Sterne's novel is considered a fundamental text for many post-World War II authors. However, Sterne's work was not without detractors even in its time; for instance, Samuel Johnson is quoted in Boswell as saying "The merely odd does not last. Tristram Shandy did not last." Denis Diderot's Jacques the Fatalist and His Master, drew many elements from Tristam Shandy, a fact not concealed in the text, making it an early example of metafiction.
20th-century history
In the 1910s, artistic experimentation became a prominent force, and various European and American writers began experimenting with the given forms. Tendencies that formed during this period later became parts of the modernist movement. The Cantos of Ezra Pound, the post-World War I work of T. S. Eliot, prose and plays by Gertrude Stein, were some of the most influential works of the time, though James Joyce's Ulysses is generally considered the most essential work of the period. The novel not only influenced more experimental writers, such as Virginia Woolf, but also less experimental writers, such as Ernest Hemingway.
The historical avant-garde movements also contributed to the development of experimental literature in the early and middle 20th century. In the Dadaist movement, poet Tristan Tzara employed newspaper clippings and experimental typography in his manifestoes. The futurist author F.T. Marinetti espoused a theory of "words in freedom" across the page, exploding the boundaries of both conventional narrative and the layout of the book itself as shown in his sound poem "novel" Zang Tumb Tumb. The writers, poets, and artists associated with the surrealist movement employed a range of unusual techniques to evoke mystical and dream-like states in their poems, novels, and prose works. Examples include the collaboratively written texts Les Champs Magnétiques (by André Breton and Philippe Soupault) and Sorrow for Sorrow, a "dream novel" produced under hypnosis by Robert Desnos.
By the end of the 1930s, the political situation in Europe had made Modernism appear to be an inadequate, aestheticized, even irresponsible response to the danger of worldwide fascism, and literary experimentalism faded from public view, kept alive through the 1940s only by isolated visionaries like Kenneth Patchen. In the 1950s, the Beat writers can be seen as a reaction against the hidebound quality of both the poetry and prose of its time, and such hovering, near-mystical works as Jack Kerouac's novel Visions of Gerard represented a new formal approach to the standard narrative of that era. American novelists such as John Hawkes started publishing novels in the late 1940s that played with the conventions of narrative.
The spirit of the European avant-gardes would be carried through the post-war generation as well. The poet Isidore Isou formed the Lettrist group, and produced manifestoes, poems, and films that explored the boundaries of the written and spoken word. The OULIPO (in French, Ouvroir de littérature potentielle, or "Workshop of Potential Literature") brought together writers, artists, and mathematicians to explore innovative, combinatoric means of producing texts. Founded by the author Raymond Queneau and mathematician François Le Lionnais, the group included Italo Calvino and Georges Perec. Queneau's Cent Mille Millards de Poèmes uses the physical book itself to proliferate different sonnet combinations, while Perec's novel Life: A User's Manual is based on the Knight's Tour on a chessboard.
