Following Rowbotham's death in 1884, his friend Lady Elizabeth Blount founded the Universal Zetetic Society, which was comprised of people committed to the belief that the Earth is flat. Today, Zetetic Astronomy both as a book and a movement lives on. A Universal Zetetic Society was created to spread the word of Samuel Rowbotham and eventually became the Flat Earth Society in 1956.

Aware of these indignant sensitivities, Rowbotham was vociferous in disputing the prevailing order. Zetetic Astronomy was founded by Samuel Rowbotham and the Zetetic approach began to gain traction by his followers after his death in 1884.

He details his experiential process within 314 pages. One success of his public challenges was that it exposed many in the scientific community to be angry and poor at coping with a man with a well-argued and contrary hypothesis. Zetetic Astrology written by Samuel Birley Rowbotham (AKA Parallax), who in life was an English inventor, writer, philosopher, and mathematician, is a scientific inquiry into the true nature of the earth and by extension the universe. Zetetic Astronomy is a key work of flat-earth thought, just as Donnellys Atlantis, the Antediluvian World is still considered required reading on the subject. Samuel Rowbotham was fiercely in favor of his theory, and asked many leading astronomers and scientists of his day to disprove it. Zetetic Astronomy, Earth Is Not a Globe An Experimental Inquiry into the True Figure of the Earth: Proving It a Plane, Without Axial or Orbital Motion. Various chapters concern such topics as motion of the heavenly bodies, sunrises, sunsets, the tidal movements, and the actual distances of the Sun and Moon from the Earth. Most of these are framed with illustrations and diagrams, that the reader better understand Rowbotham's explanations. Upon the pages are many experiments and demonstrations, all of which are conducted in support of the Earth being flat, with the astronomical bodies situated above, rather than all around it. Keen to let the hypothesis stand on its own merits, this book was first published under the pseudonym of 'Parallax'. Eventually, in 1881, the author greatly expanded and published this book, in part to meet demands of public and scientific scrutiny. Rowbotham was already a known inventor and author at the time, over time the theories of Zetetic Astronomy - in which the Earth is portrayed as flat - became popular. This book originally began as a short pamphlet in the 1840s, explaining the basics of the theory with a few sketches alongside. It was based in a 16-page pamphlet written by him in 1849, and was an expansion for it. This premium edition contains all of Rowbotham's original graphs, charts and drawings. Zetetic Astronomy: The Earth Not a Globe or simply Earth Not a Globe is a 430-page book written in 1881 by Samuel Rowbotham, under the pseudonym Parallax. The foundations or premises are always unproved no proof is ever attempted the necessity for it is denied it is considered sufficient that the assumptions shall seem to explain the phenomena selected.Samuel Birley Rowbotham advances the Flat Earth theory, which holds that Earth is not in fact an oblate spheroid planet, but an enclosed plane above which the astronomical bodies are situated. None can doubt that by making special experiments and collecting manifest and undeniable facts, arranging them in logical order, and observing what is naturally and fairly deducible, the result will be far more consistent and satisfactory than by framing a theory or system and assuming the existence of causes for which there is no direct evidence, and which can only be admitted 'for the sake of argument'.The Newtonian and all other 'systems of nature' are little better than the 'hypothesis of the terrestrial motion' of Copernicus. His arguments continue to captivate, persuade, and entertain up to the present day.ДЄs Rowbotham puts it, 'The term zetetic is derived from the Greek verb zeteo which means to search or examine - to proceed only by inquiry. Drawing from a wide variety of contemporary sources, Christian scripture, and his own investigative and experimental skills, Rowbotham advocated tirelessly for his thesis that the true shape of the Earth was a plane, refuting all suggestions of rotundity. Zetetic Astronomy is the magnum opus of Samuel Rowbotham (1816-1884), a self-taught polymath, debater, faith healer, and early advocate of Utopian socialism.
