   • 1916, William Ellery Leonard, transl., On the Nature of Things, New York: E. P. Dutton, translation of De rerum natura by Lucretius, →OCLC, Book 2, lines 218–227:

     The atoms, as their own weight bears them down / Plumb through the void, at scarce determined times, / In scarce determined places, from their course / Decline a little – call it, so to speak, / Mere changed trend. For were it not their wont / Thuswise to swerve, down would they fall, each one, / Like drops of rain, through the unbottomed void; / And then collisions ne'er could be nor blows / Among the primal elements; and thus / Nature would never have created aught.
