Etidorhpa; or, The End of Earth.
 The Strange History of a Mysterious Being and the Account of a Remarkable Journey

"Etidorhpa; or, The End of Earth." by John Uri Lloyd is a scientific allegory published in 1895. A mysterious being called I-Am-The-Man dictates his remarkable journey to a man named Llewyllyn Drury. After being kidnapped by a secret society, the narrator is taken into a Kentucky cave and guided deep into the earth's core. The story blends adventure with speculative ideas about alchemy, Masonic orders, and transcending physical reality in this hollow earth tale.
