Nor need there be for men Astonishment that yonder sun so small Can yet send forth so great a light as fills Oceans and all the lands and sky aflood, And with its fiery exhalations steeps The world at large. For it may be, indeed, That one vast-flowing well-spring of the whole Wide world from here hath opened and out-gushed, And shot its light abroad; because thuswise The elements of fiery exhalations From all the world around together come, And thuswise flow into a bulk so big 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. And possibly the sun, Agleam on high with rosy lampion, Possesses about him with invisible heats A plenteous fire, by no effulgence marked, So that he maketh, he, the Fraught-with-fire, Increase to such degree the force of rays. Nor is there one sure cause revealed to men How the sun journeys from his summer haunts On to the mid-most winter turning-points In Capricorn, the thence reverting veers Back to solstitial goals of Cancer; nor How 'tis the moon is seen each month to cross That very distance which in traversing The sun consumes the measure of a year. I say, no one clear reason hath been given For these affairs. Yet chief in likelihood Seemeth the doctrine which the holy thought Of great Democritus lays down: that ever The nearer the constellations be to earth The less can they by whirling of the sky Be borne along, because those skiey powers Of speed aloft do vanish and decrease In under-regions, and the sun is thus Left by degrees behind amongst those signs That follow after, since the sun he lies Far down below the starry signs that blaze; And the moon lags even tardier than the sun: In just so far as is her course removed From upper heaven and nigh unto the lands, In just so far she fails to keep the pace With starry signs above; for just so far As feebler is the whirl that bears her on, (Being, indeed, still lower than the sun), In just so far do all the starry signs, Circling around, o'ertake her and o'erpass. Therefore it happens that the moon appears More swiftly to return to any sign Along the Zodiac, than doth the sun, Because those signs do visit her again
