T. Lucretius Carus, Of The Nature of Things — Book V (1916)
“ That from one single fountain-head may stream This heat and light. And seest thou not, indeed, How widely one small water-spring may wet The meadow-lands at times and flood the fields? 'Tis even possible, besides, that heat From forth the sun's own fire, albeit that fire Be not a great, may permeate the air With the fierce hot--if but, perchance, the air Be of condition and so tempered then As to be kindled, even when beat upon Only by little particles of heat-- Just as we sometimes see the standing grain Or stubble straw in conflagration all From one lone spark. ”
