Early European explorers left the continent with visions of gardens in their heads: The Garden of Eden, the Garden of the Hesperides, and other mythic realms of abundance, ease, and endless repose. Those same explorers left sickness, war, and death only to find sickness, war, and death—much of it exported by themselves. The garden became de-mythologized. Natural philosophy and modern methods of agriculture brought gardens further down to earth in the cultural imagination.
