Niels Klim's Underground Travels, originally published in Latin as "Nicolai Klimii Iter Subterraneum" (1741) is a satirical science-fiction/fantasy novel written by Ludvig Holberg, a Norwegian-Danish dramatist, historian, and essayist, born in Bergen, Norway. It was his first and only novel. It describes a utopian society from an outsider's point of view, and often pokes fun at diverse cultural and social topics such as moral, science, sexual equality, religion, governments, and philosophy.
