The Hollow Earth is a concept proposing that the planet Earth is entirely hollow or contains a substantial interior space. Notably suggested by Edmond Halley in the late 17th century, the notion was disproven, first tentatively by Pierre Bouguer in 1740, then definitively by Charles Hutton in his Schiehallion experiment around 1774.
William Sydney Graham was a Scottish poet, who was often associated with Dylan Thomas and the neo-romantic group of poets. Graham's poetry was mostly overlooked in his lifetime; however, partly thanks to the support of Harold Pinter, his work was eventually acknowledged. He was represented in the second edition of the Penguin Book of Contemporary Verse and the Anthology of Twentieth-Century British and Irish Poetry.
Hugh Barnett Cave was an American writer of various genres, perhaps best remembered for his works of horror, weird menace and science fiction. Cave was one of the most prolific contributors to pulp magazines of the 1920s and '30s, selling an estimated 800 stories not only in the aforementioned genres but also in western, fantasy, adventure, crime, romance and non-fiction. He used a variety of pen names, notably Justin Case under which name he created the antihero The Eel. A war correspondent during World War II, Cave afterwards settled in Jamaica where he owned and managed a coffee plantation and continued his writing career, now specializing in novels as well as fiction and non-fiction sales to mainstream magazines.
Subterranean fiction is a subgenre of adventure fiction, science fiction, or fantasy which focuses on fictional underground settings, sometimes at the center of the Earth or otherwise deep below the surface. The genre is based on, and has in turn influenced, the Hollow Earth theory. The earliest works in the genre were Enlightenment-era philosophical or allegorical works, in which the underground setting was often largely incidental. In the late 19th century, however, more pseudoscientific or proto-science-fictional motifs gained prevalence. Common themes have included a depiction of the underground world as more primitive than the surface, either culturally, technologically or biologically, or in some combination thereof. The former cases usually see the setting used as a venue for sword-and-sorcery fiction, while the latter often features cryptids or creatures extinct on the surface, such as dinosaurs or archaic humans. A less frequent theme has the underground world much more technologically advanced than the surface one, typically either as the refugium of a lost civilization, or as a secret base for space aliens.
Édouard-Alfred Martel, the 'father of modern speleology', was a world pioneer of cave exploration, study, and documentation. Martel explored thousands of caves in his native France and many other countries, popularised the pursuit of cave exploration, introduced the concept of speleology as a distinct area of scientific study, maintained an extensive archive, and in 1895 founded Société de Spéléologie, the first organisation devoted to cave science in the world.
