Pouring forth its seas everywhere, then, the ocean envelops the earth and fills its deeper chasms.
Nicolaus CopernicusThe massive bulk of the earth does indeed shrink to insignificance in comparison with the size of the heavens.
Nicolaus CopernicusFor it is the duty of an astronomer to compose the history of the celestial motions through careful and expert study.
Nicolaus CopernicusIn the first book I shall describe all the positions of the spheres, along with the motions which I attribute to the Earth, so that the book will contain as it were the general structure of the universe. In the remaining books I relate the motions of the remaining stars, and all the spheres, to the mobility of the Earth, so that it can be thence established how far the motions and appearances of the remaining stars and spheres can be saved, if they are referred to the motions of the Earth.
