At the Earth's Core

At the Earth's Core by Edgar Rice Burroughs (1914)

David Innes and inventor Abner Perry drill through the Earth's crust in a mechanical "iron mole" and discover Pellucidar — a savage prehistoric world inside the hollow Earth, lit by a central sun, where humans are enslaved by telepathic reptiles.

Historical Significance:
Published in 1914, At the Earth's Core launched Burroughs' Pellucidar series — seven novels set inside a hollow Earth populated by dinosaurs, cavemen, and bizarre creatures. The hollow Earth theory was still taken semi-seriously in the early 20th century, and Burroughs exploited it brilliantly. The novel's influence extends to every "lost world" and "journey to the center of the earth" story that followed. The 1976 film starred Peter Cushing and Doug McClure.
