Philosophiæ Naturalis Principia Mathematica

Newton's Mathematical Principles of Natural Philosophy, in which he states the three laws of motion and the law of universal gravitation and derives from them the motions of the planets, the comets, the Moon and the tides. Three books: the motion of bodies, the motion of bodies in resisting media, and the system of the world. This is the first edition (London, 1687), printed by Joseph Streater for the Royal Society with Edmond Halley seeing it through the press, here as a scan of the Boston Public Library copy.
