"Copernicus, who rightly did condemn This oldest system, form'd a wiser scheme; In which he leaves the Sun at Rest, and rolls The orb terrestrial on its proper poles; Which makes the night and day by this career, And by its slow and crooked course the year. The famous Dane, who oft the modern guides, To earth and sun their Provinces divides: The earth's rotation makes the night and day, The sun revolving through th'eccliptic way Effects the various seasons of the year, Which in their turn for happy ends appear. This scheme or that, which pleases best, embrace, Still we the fountain of their motion trace. Kepler asserts these wonders may be done By the magnetic vertue of the sun, Which he, to gain his end, thinks fit to place Full in the center of that mighty space, Which does the spheres, where planets roll, include, And leaves him with attractive force endu'd. The sun, thus seated, by mechanic laws, The earth, and every distant planet draws; By which attraction all the planets found Within his reach, are turn'd in ether round."
