This book is about legends of the Hollow Earth and other underground cities and civilizations. The concept of there being a hollow Earth or inner area of the Earth where people have lived and do now has been around for hundreds of years. Other stories and legends of underground cities are also discussed to show that there are many stories of people and other beings living underground in our past and maybe up until the present era. Usually there is some fact as the basis for legends so all these stories make we wonder if there is some reality about civilizations existing underground on this Earth. These legends are geographically diverse and from different cultures so maybe there is something to them. Near the end of the book I include some incredible science data about life actually existing miles under our Earth and an example of a real underground city we know about and have visited.

1983 Highly illustrated. Gives much valuable information on the hollow earth, hollow earth societies, early hollow earth pioneers or "In-Earthologists".

1964 Dr. Bernard says this is the true home of the flying saucers. the epoch-making significance of Adm. Byrd's flight for 1,700 miles into the North Polar opening leading to the hollow interior of the earth, the home of a Super Race who are the Creators.

Beliefs in mysterious underworlds are as old as humanity. But the idea that the earth has a hollow interior was first proposed as a scientific theory in 1691 by Sir Edmond Halley (of comet fame), who suggested that there might be life down there as well. Hollow Earth traces the surprising, marvelous, and just plain weird permutations his ideas have taken over the centuries. From science fiction to utopian societies and even religions, Hollow Earth travels through centuries and cultures, exploring how each era's relationship to the idea of a hollow earth mirrored its hopes, fears, and values. Illustrated with everything from seventeenth-century maps to 1950s pulp art to movie posters and more, Hollow Earth is for anyone interested in the history of strange ideas that just won't go away.

Possessing extraordinary powers, including the ability to bring artwork to life, twelve-year-old twins Matt and Emily are sought by villains trying to access the terrors of Hollow Earth, a place where demons and mythological beasts lie trapped for eternity.
