The burly winds (that over-sweep amain)
And skiey sun (that with his rays dissolves)
Do minish the level seas; in part because
The water is diffused underground
Through all the lands. The brine is filtered off,
And then the liquid stuff seeps back again
And all regathers at the river-heads,
Whence in fresh-water currents on it flows
Over the lands, adown the channels which
Were cleft erstwhile and erstwhile bore along
The liquid-footed floods.
Now, then, of air
I'll speak, which hour by hour in all its body
Is changed innumerably. For whatso'er
Streams up in dust or vapour off of things,
The same is all and always borne along
Into the mighty ocean of the air;
And did not air in turn restore to things
Bodies, and thus recruit them as they stream,
All things by this time had resolved been
And changed into air. Therefore it never
Ceases to be engendered off of things
And to return to things, since verily
In constant flux do all things stream.
Likewise,
