De ontdekkers ...
"In medieval times there was a return to the concept of a flat Earth and a dogmatism about the crystalline celestial spheres, here epitomized in a woodcut showing the machinery responsible for their motion discovered by an inquirer who has broken through the outer sphere of fixed stars. Sixteenth century." J.D. Bernal, Science in History, vol. 1 of The Emergence of Science (4 vols)
