"I took vigorous exercise. I breathed the free air of Heaven. I thought upon other subjects than Death. I discarded my medical books. "Buchan" I burned.

- Edgar Allen Poe, The Premature Burial 1850
origin: (1300's) Middle English cokaygne, from Middle French cocaigne= land of plenty

- Edgar Allen Poe, The Angel of the Odd (1844)
