ELYSIUMn. [1.] An imaginary delightful country which the ancients foolishly believed to be inhabited by the spirits of the good. This ridiculous and mischievous fable was swept off the face of the earth by the early Christians — may their souls be happy in Heaven! [2.] The Heaven of the ancients.Nothing could be more ludicrous than this crude conception; instead of golden clouds, harps, crowns and a great white throne, there were fields, groves, streams, flowers and temples. In the ancient Elysium we have a signal example of the inferiority of pagan imagination to Christian knowledge.
