Joseph
H. Cater, in his book The Ultimate Reality, has the following comments to make
regarding the book Etidorhpa:
“ It is important at this stage to mention a book concerning the hollow Earth,
the finest that has yet been written. It not only contains more important
factual information than any other book, but also goes far beyond them in other
respects. This great book probably contains more profound metaphysical and
scientific truths than any other book written up to the present. The book is
entitled Etidorhpa and was first published in 1895. Some books are written in
the form of a novel in order to present certain ideas or truths without inviting
undue -attack from various quarters. Etidorhpa is considered by most to be a
science fiction book. Any intelligent and discerning reader realizes that it
isn't.
The book concerns a story within a story. In Cincinnati, Ohio, during the
1860's, a young student of science had an unusual visitation from a mysterious
stranger of striking appearance. This strange man, whose name was never
revealed, extracted a promise from this student to publish a manuscript which
the stranger was to read to him. The time of the publication was to be 30 years
later. The manuscript was then read aloud over a period of time requiring many
sessions. After the last reading the manuscript was presented to him along with
sealed instructions to be opened at the prescribed time.
According to the subject matter of the manuscript, the stranger was taken into
the hollow of the earth through a cave in Kentucky during the early part of the
nineteenth century. His guide was a cavern dweller who was a member of a secret
organization whose objective was the preservation of vital knowledge for the
future enlightenment of mankind. The objective of this trip was the inner shell
of the earth, where the nameless one was to receive advanced schooling in the
mysteries of the universe.
The book Etidorhpa described this amazing trip through the caverns of the inner
earth in detail. It also presented some of the philosophy and scientific truths
the guide imparted to this man."
