Chimera is a 1972 novel by the American writer John Barth, composed of three loosely connected novellas. The novellas are Dunyazadiad, Perseid and Bellerophoniad, whose titles refer eponymously to the mythical characters Dunyazad, Perseus and Bellerophon (slayer of the mythical Chimera). The book is an example of postmodernism, which can be seen in its metafictional content and its incorporation of stylistic elements that go beyond the traditional novel genre. It shared the U.S. National Book Award for Fiction with Augustus by John Edward Williams.
