Samuel Birley Rowbotham, under the pseudonym 'Parallax', lectured for two decades up and down Britain promoting his unique flat earth theory. In this book he lays out his world system.
- Rowbotham believed that the earth is flat; that the continents float on an ocean which has a layer of fire under it; that the lands we know are surrounded by an infinite wilderness of ice and snow, beyond the Antarctic ocean, bordered by an immense circular ice-cliff.
- The Zetetic Sun, moon, planets and stars are all only a few hundred miles above the surface of the earth. Needless to say, to make his system work, the author had to throw out a great deal of science.
