Journey to the Underground World

Journey to the Underground World is a science fiction adventure novel that launches Lin Carter's Zanthodon series. A professor and an adventurer discover an entrance to a vast underground realm beneath the Sahara Desert, where prehistoric creatures and ancient human civilizations have survived. The story takes place in Zanthodon, a massive subterranean cavern 100 miles below the Earth's surface. This hidden world spans 500 miles and serves as a sanctuary for prehistoric life forms and human societies from different historical periods. The narrative follows Professor Potter and Eric Carstairs as they venture into this primitive realm by helicopter through a volcanic shaft. After becoming stranded, they encounter dinosaurs, mammoths, Neanderthals, and various human tribes who inhabit this lost world. The book explores themes of survival, adaptation, and the coexistence of different species and civilizations isolated from the modern world. Carter's work fits into the tradition of "hollow earth" science fiction while adding his own perspective on human nature and prehistoric life.

🦕 Carter wrote this book as an homage to Edgar Rice Burroughs' Pellucidar series, which also featured a prehistoric world inside the Earth 🌋 The concept of a hollow Earth was actually considered scientifically plausible in the 18th and early 19th centuries, with some expeditions even planned to find polar entrances 📚 Lin Carter was not only an author but also edited the influential Ballantine Adult Fantasy series, which helped revive interest in classic fantasy literature 🦖 The book's "Stone Age Glossary" includes real prehistoric creatures that existed during different time periods, though they wouldn't have actually coexisted as depicted in the story 🗺️ Zanthodon is the first book in a five-volume series, though Carter originally planned for the series to be much longer before his death in 1988
