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 More swiftly than they visit the great sun. It can be also that two streams of air Alternately at fixed periods Blow out from transverse regions of the world, Of which the one may thrust the sun away From summer-signs to mid-most winter goals And rigors of the cold, and the other then May cast him back from icy shades of chill Even to the heat-fraught regions and the signs That blaze along the Zodiac. So, too, We must suppose the moon and all the stars, Which through the mighty and sidereal years Roll round in mighty orbits, may be sped By streams of air from regions alternate. Seest thou not also how the clouds be sped By contrary winds to regions contrary, The lower clouds diversely from the upper? Then, why may yonder stars in ether there Along their mighty orbits not be borne By currents opposite the one to other?
