De revolutionibus orbium coelestium

1543

De revolutionibus orbium coelestium, meaning On the Revolutions of the Heavenly Spheres, is the book in which Nicolaus Copernicus set out a model of the universe with the Sun at the centre and the Earth and other planets orbiting it. Copernicus had developed his ideas over several decades and was persuaded by the mathematician Georg Joachim Rheticus to publish. The work was printed in Nuremberg, and tradition holds that Copernicus received a copy just before his death. A preface added by the theologian Andreas Osiander presented the theory as a mathematical device rather than a true description. The book started what is now called the Copernican revolution, and influenced Galileo and Kepler. The Catholic Church placed it on its Index of prohibited books in 1616.
