A mysterious name from early American speculative fiction, this pseudonymous author is best known for Symzonia, an 1820 voyage tale that carries readers into a hollow-earth utopia. The identity behind the name has never been settled, which only adds to the book’s strange charm.

by Captain Adam Seaborn
Published under the name Captain Adam Seaborn, Symzonia: A Voyage of Discovery appeared in 1820 and is widely noted as an early work of American speculative fiction. The novel mixes sea adventure, satire, and hollow-earth fantasy, following an expedition toward the South Pole and into an imagined inner world.
The name Captain Adam Seaborn was a pseudonym, and the real author remains uncertain. Reference sources describe the authorship as unidentified, while some scholars have connected the book to John Cleves Symmes Jr., and others have suggested different figures, including Nathaniel Ames.
That uncertainty has become part of Seaborn’s lasting interest. Even without a confirmed biography, the name is tied to one of the oddest and most imaginative literary works of its era—a book that helped secure a place in the early history of science fiction and utopian adventure.
