Eureka

Eureka (1848) is a lengthy non-fiction work by American author Edgar Allan Poe (1809-1849) which he subtitled "A Prose Poem," though it has also been subtitled as "An Essay on the Material and Spiritual Universe." Adapted from a lecture he had presented, Eureka describes Poe's intuitive conception of the nature of the universe with no antecedent scientific work done to reach his conclusions.
