Zetetic Astronomy: The Earth not a Globe is a book published by Samuel Rowbotham in 1865. It is considered one of the foundational works of the modern-day flat Earth movement, containing the sum of Rowbotham's ideas on the subject.
Content
In his book, Rowbotham expanded his ideas from his 1849 pamphlet Zetetic Astronomy and proposed that Earth is a flat disc centred at the North Pole and bounded along its southern edge by a wall of ice, Antarctica. Rowbotham further held that the Sun and Moon were 3,000 miles (4,800 km) above Earth and that the "cosmos" was 3,100 miles (5,000 km) above Earth.
