Zetetic Astronomy: Earth Not a Globe!an Experimental Inquiry into the True Figure of the Earth Etc.

In 1865, a writer using the pseudonym Parallax embarked on an ambitious project: to dismantle the prevailing scientific consensus that the Earth is a globe through a series of personal experiments and observations. The result is Zetetic Astronomy, a sprawling work that argues, through canal water levels, horizon visibility, and the behavior of light, that humanity has been deceived about the planet's true shape. The term 'zetetic' derives from the Greek for 'seeker,' and Parallax positions himself as an empiricist who trusts only what his own eyes can confirm, dismissing centuries of astronomical development as theoretical speculation unsupported by direct observation. What emerges is not merely a scientific treatise but a window into the Victorian era's rich tradition of heterodox thinking, when industrialization and rapid scientific change spawned countless alternative cosmologies. The book laid groundwork for the modern flat Earth movement, yet it functions equally well as a period curiosity, revealing how 19th-century thinkers grappled with questions of proof, authority, and the limits of human perception. Reading it today offers equal parts historical fascination and methodological caution: a reminder that confident observation alone, without theoretical framework, can lead even intelligent minds to startling conclusions.
