A New Philosophy of Our Sublunar World (De Mudo Nostro Sublunari) by the late William Gilbert expresses ideas consistent with those of the late Copernicus that the Earth rotates on its axis; it states that fixed stars are at varying distances from the Earth and that a form of magnetism is what holds planets in their orbits. His brother has edited two manuscripts that were left at Gilbert's death to produce the work.
