Could not subside, nor all the parts of ground Settle alike to one same level there. Thus, then, the massy weight of earth stood firm With now concreted body, when (as 'twere) All of the slime of the world, heavy and gross, Had run together and settled at the bottom, Like lees or bilge. Then ocean, then the air, Then ether herself, the fraught-with-fire, were all Left with their liquid bodies pure and free, And each more lighter than the next below; And ether, most light and liquid of the three, Floats on above the long aerial winds, Nor with the brawling of the winds of air Mingles its liquid body. It doth leave All there--those under-realms below her heights-- There to be overset in whirlwinds wild,-- Doth leave all there to brawl in wayward gusts, Whilst, gliding with a fixed impulse still, Itself it bears its fires along. For, lo, That ether can flow thus steadily on, on, With one unaltered urge, the Pontus proves-- That sea which floweth forth with fixed tides, Keeping one onward tenor as it glides. And that the earth may there abide at rest In the mid-region of the world, it needs Must vanish bit by bit in weight and lessen, And have another substance underneath, Conjoined to it from its earliest age In linked unison with the vasty world's Realms of the air in which it roots and lives. On this account, the earth is not a load, Nor presses down on winds of air beneath; Even as unto a man his members be Without all weight--the head is not a load Unto the neck; nor do we feel the whole Weight of the body to centre in the feet. But whatso weights come on us from without, Weights laid upon us, these harass and chafe, Though often far lighter. For to such degree It matters always what the innate powers Of any given thing may be. The earth Was, then, no alien substance fetched amain, And from no alien firmament cast down On alien air; but was conceived, like air, In the first origin of this the world, As a fixed portion of the same, as now Our members are seen to be a part of us.
