Though somewhat uneven throughout, John Barth's Chimera is an enjoyable and complex read, particularly for those with an interest in Ancient Mythology and Post Modern fiction. This "novel," written sometime after Giles Goat-Boy and Lost in the Funhouse, is comprised of three very loosely connected novellas, all taking post-modern slants on classic mythological stories.
"Dunyaziad" is a brief recounting of the 1001 Arabian Nights and the plight that Princess Scheherazade and her sister faced after recounting those 1001 stories to their tyrannical husbands. Don't worry if you've never read the real 1001 Nights: Barth provides enough context that you'll quickly figure out what's going on. You'll probably want to go out and read the original tales after you're done, because he does a great job of making these tales seem mysterious and intriguing.
"Perseiad" is tale of Perseus and his mid-life crisis after slaying Medusa and separating from his wife. This is definitely the best tale of the three and is very similar to Barth's earlier tales "Menelaiad" and "Anonymiad" from Lost in the Funhouse. The digressions are minimal, the plot perfectly formed (spiralic if you will), and the sense of impotency, confusion, and frustration very tangible.
"Bellerophoniad" is a self-conscious imitation of "Persiad" and probably the most difficult story of the three. It definitely has its good parts, but some of the post-modern digressions (particularly the lengthy account of characters originally found in Giles Goat-Boy, and notes from a lecture delivered on Barth's fiction itself) can really be tedious.
Once again, don't be frightened off by the copious references to mythological characters and events, even if you aren't previously familiar with them. Barth goes out of his way to bring you up to speed, even citing a passage from Robert Graves' The Greek Myths to give you a very literal account of Bellerophon's myth. All of Barth's trademark wit and complexity are here, and there is plenty of sex, violence, and humor (sometimes all three at once) to keep you entertained. If you are a new reader to Barth, you are much better off reading The Sot-Weed Factor or Lost in the Funhouse, but to those who already consider themselves devoted fans, this is a must-read.
