A polemical 19th-century work that argues for the existence of an advanced prehistoric civilization in the Atlantic whose destruction by a cataclysmic flood scattered survivors who became the founders of later cultures; the author assembles comparative mythology, linguistics, archaeology, and geologic speculation to trace common symbols, flood legends, and technological parallels among Egypt, Mesopotamia, Greece, and the Americas, claiming these point to a single antediluvian source of civilization—an interpretation that popularized the Atlantis hypothesis but rests on speculative methods and conclusions widely challenged by later scholarship.
