Zetetic Astronomy: Earth Not a Globe by Samuel Rowbotham is a 19th-century work that challenges the widely accepted notion of a spherical Earth, advocating instead for a flat Earth model. Based on Rowbotham's "Zetetic" method-a form of inquiry emphasizing observation and experience over theoretical science-the book presents arguments and experiments that Rowbotham claimed supported his flat Earth hypothesis. It discusses topics like the horizon's appearance, the behavior of water, and celestial phenomena, aiming to refute conventional astronomical science. While widely discredited by modern science, the book remains a historical curiosity, reflecting the period's scientific debates and the enduring appeal of alternative perspectives.
