Captain Adam Seaborn

Published as Captain Adam Seaborn, the author of Symzonia: A Voyage of Discovery remains uncertain today. Reliable reference sources describe Seaborn as a pseudonym, and the real writer has not been identified with confidence.

Symzonia, printed in 1820, is now remembered as an early work of speculative fiction and subterranean or hollow-earth literature. The story follows a voyage toward the South Pole and imagines a hidden inner world, giving the book a lasting place in the history of fantastical adventure writing.

Some scholars have linked the pseudonym to John Cleves Symmes Jr., the American advocate of hollow-earth theory, while others have argued for different authors, including Nathaniel Ames. Because that authorship is still disputed, the most accurate way to present Captain Adam Seaborn is as the intriguing pen name behind one unusual and influential early American fantasy.
