O is for "The Devil's Dictionary" (No. 186 in a series)

The Devil's Dictionary is a satirical dictionary written by Ambrose Bierce (1842-c.1914, caricatured above by David Levine). Bierce was an American author who began the book as a newspaper serial. First published in 1906 as The Cynic's Word Book, it was retitled in 1911, using the name we know it by today, which is the title that Bierce preferred. Some of the definitions have not aged all that well, but many have.

OPERA, n. A play representing life in another world, whose inhabitants have no speech but song, no motions but gestures and no postures but attitudes. All acting is simulation, and the word simulation is from simia, an ape; but in opera the actor takes for his model Simia audibilis (or Pithecanthropos stentor)—the ape that howls.
