Peter Kolosimo’s Il pianeta sconosciuto (1969) is a landmark in the field of pseudoarchaeology and speculative non-fiction. Blending elements of science, myth, and science fiction, Kolosimo explores the idea of lost civilizations, extraterrestrial visitors, and unexplained artifacts. His narrative moves between archaeological enigmas, legends, and alternative cosmologies, questioning orthodox history and suggesting the presence of a hidden past that connects humanity with the cosmos. Though often criticized by academics, the book remains influential as part of the 20th-century current of ancient astronaut theories and alternative historiography, reflecting both the cultural fascination with space and the era’s spirit of speculative exploration.
