Famous quotes containing the word arcadia:
“To value the tradition of, and the discipline required for, the craft of fiction seems today pointless. The real Arcadia is a lonely, mountainous plateau, overbouldered and strewn with the skulls of sheep slain for vellum and old bitten pinions that tried to be quills. It’s forty rough miles by mule from Athens, a city where there’s a fair, a movie house, cotton candy.”
—Alexander Theroux (b. 1940)
