[Public Domain Review] Stories of a Hollow Earth

[Public Domain Review]

In 1741 the Norwegian-Danish author Ludvig Holberg published Klimii
Iter Subterraneum, a satirical science-fiction/fantasy novel detailing
the adventures of its hero Niels Klim in a utopian society existing
beneath the surface of the earth. Peter Fitting, author of
Subterranean Worlds: A Critical Anthology, explores Holberg’s book in
the wider context of the hollow earth theory.
