Chimera by John Barth
Chimera is a 1972 novel in the form of three loosely connected novellas by John Barth. The novellas are Dunyazadiad, Perseid and Bellerophoniad, the eponyms of which are Dunyazad, Perseus and Bellerophon, the last of whom slew the Chimera. This work exemplifies postmodernism, with several Q&A sessions and three diagrams (all in Bellerophoniad). Chimera won the National Book Award for Fiction in 1973.
