Symzonia - A Voyage of Discovery (Paperback)

First published in 1820, Symzonia is the first fictional work to explore the hollow earth theory. The tale tells of Captain Seaborn's expedition to the North Pole to discover the entrance to the hollow earth. A classic early work of utopian fiction (perhaps the first American example), Symzonia is also a great seafaring tale complete with a mutinous crew member. Seaborn discovers the entrance to the Earth and finds inside our planet a technologically advanced civilization. He names the society Symzonia and promptly claims them in the name of the United States.
