The idea that the Earth is hollow has inspired both the world of science and the world of fiction. As a scientific concept, this notion has informed the works of Edmond Halley and Leonhard Euler. As a literary conceit, it can be found in the works of Dante and E.A. Poe; in novels by Jules Verne, Arno Schmidt, Thomas Pynchon, and Mark Z. Danielewski; and in comics, films, and computer games. This collection addresses both the scientific and the aesthetic aspects of the "Hollow Earth," with essays that range from medieval literature to afrofuturism.
