John Barth, Chimera (1972)
This book is actually three
novellas--or if we want to be a bit finer with out classifications, a
long short story, a novella, and a short novel, all on mythological
themes. Only the final story, "Bellerephoniad," is
published here for the first time; "Dunyazadiad" and
"Perseid" had previously appeared in Esquire and Harper's
respectively. They're sufficiently thematically unified that
gathering them all together makes sense, however.
