Parallax 
Zetetic Astronomy – Earth Not a Globe! An Experimental Inquiry into the True Figure of the Earth: Proving it a Plane, Without Axial or Orbital Motion; and the Only Material World in the Universe! 

Zetetic Astronomy is a classic 1881 volume on Flat Earth theory that gives a fascinating introduction to zetetic astronomy and the work of Samuel Birley Rowbotham.

What if the Earth isn’t a globe like we’ve been told? What if, instead, it is an enclosed plane surrounded by a wall of ice with the North Pole at its centre?

Writing under the pseudonym of Parallax, Samuel Birley Rowbotham breaks down his alternative ideas and introduces zetetic astronomy in this 1865 treatise. This classic volume is a great introduction to Flat Earth theory and is sure to initiate many interesting conversations.

Rowbotham disputes science by offering his own theories. He explores the idea that the Earth is flat and that below us is a layer of fire. The planets and stars that modern science state to be millions of kilometers and lightyears away are, according to Rowbotham, within just a few hundred miles of the Earth’s surface.

Zetetic Astronomy is a faith-based science of cosmos and provides riveting explanations for Flat Earth thought. Incorporating his strong Christian beliefs with his evidence, Rowbotham argues that Heaven and Hell are in existence above and below our planet respectively.

This high-quality volume features chapters such as:

– Introduction – Experiments proving the Earth to be a Plane


– The Earth no Axial or Orbital Motion


– The True Distance of the Sun and Stars


– The Sun moves in a Circle over the Earth, concentric with the North Pole


– Diameter of Sun’s path Constantly Changing


– Causes of Day and Night, Seasons, &c.


– Cause of ‘Sun Rise’ and ‘Sun Set’

Proudly republished by Obscure Press in this beautiful new edition, Zetetic Astronomy is a must-read for those with an interest in Flat Earth theory, and is not to be missed by vintage literature collectors.
