De Rerum Natura

Lucretius. De Rerum Natura. William Ellery Leonard. E. P. Dutton. 1916.

Into being
The clouds condense, when in this upper space
Of the high heaven have gathered suddenly,
As round they flew, unnumbered particles-
World's rougher ones, which can, though interlinked
With scanty couplings, yet be fastened firm,
The one on other caught. These particles
First cause small clouds to form; and, thereupon,
These catch the one on other and swarm in a flock
And grow by their conjoining, and by winds
Are borne along, along, until collects
The tempest fury. Happens, too, the nearer
The mountain summits neighbour to the sky,
The more unceasingly their far crags smoke
With the thick darkness of swart cloud, because
When first the mists do form, ere ever the eyes
Can there behold them (tenuous as they be),
The carrier-winds will drive them up and on
Unto the topmost summits of the mountain;
And then at last it happens, when they be
In vaster throng upgathered, that they can
By this very condensation lie revealed,
And that at same time they are seen to surge
From very vertex of the mountain up
Into far ether. For very fact and feeling,
As we up-climb high mountains, proveth clear
That windy are those upward regions free.

Besides, the clothes hung-out along the shore,
When in they take the clinging moisture, prove
That nature lifts from over all the sea
Unnumbered particles. Whereby the more
'Tis manifest that many particles
Even from the salt upheavings of the main
Can rise together to augment the bulk
Of massed clouds. For moistures in these twain
Are near akin. Besides, from out all rivers,
As well as from the land itself, we see
Up-rising mists and steam, which like a breath
Are forced out from them and borne aloft,
To curtain heaven with their murk, and make,
By slow foregathering, the skiey clouds.
For, in addition, lo, the heat on high
Of constellated ether burdens down
Upon them, and by sort of condensation
Weaveth beneath the azure firmament
The reek of darkling cloud. It happens, too,
That hither to the skies from the Beyond
Do come those particles which make the clouds
And flying thunderheads. For I have taught
That this their number is innumerable
And infinite the sum of the Abyss,
And I have shown with what stupendous speed
Those bodies fly and how they're wont to pass
Amain through incommunicable space.
Therefore, 'tis not exceeding strange, if oft
In little time tempest and darkness cover
With bulking thunderheads hanging on high
The oceans and the lands, since everywhere
Through all the narrow tubes of yonder ether,
Yea, so to speak, through all the breathing-holes
Of the great upper-world encompassing,
There be for the primordial elements
Exits and entrances.

Now come, and how
The rainy moisture thickens into being
In the lofty clouds, and how upon the lands
'Tis then discharged in down-pour of large showers,
I will unfold. And first triumphantly
Will I persuade thee that up-rise together,
With clouds themselves, full many seeds of water
From out all things, and that they both increase-
Both clouds and water which is in the clouds-
In like proportion, as our frames increase
In like proportion with our blood, as well
As sweat or any moisture in our members.
Besides, the clouds take in from time to time
Much moisture risen from the broad marine,-
Whilst the winds bear them o'er the mighty sea,
Like hanging fleeces of white wool. Thuswise,
Even from all rivers is there lifted up
Moisture into the clouds. And when therein
The seeds of water so many in many ways
Have come together, augmented from all sides,
The close-jammed clouds then struggle to discharge
Their rain-storms for a two-fold reason: lo,
The wind's force crowds them, and the very excess
Of storm-clouds (massed in a vaster throng)
Giveth an urge and pressure from above
And makes the rains out-pour. Besides when, too,
The clouds are winnowed by the winds, or scattered
Smitten on top by heat of sun, they send
Their rainy moisture, and distil their drops,
Even as the wax, by fiery warmth on top,
Wasteth and liquefies abundantly.
But comes the violence of the bigger rains
When violently the clouds are weighted down
Both by their cumulated mass and by
The onset of the wind. And rains are wont
To endure awhile and to abide for long,
When many seeds of waters are aroused,
And clouds on clouds and racks on racks outstream
In piled layers and are borne along
From every quarter, and when all the earth
Smoking exhales her moisture. At such a time
When sun with beams amid the tempest-murk
Hath shone against the showers of black rains,
Then in the swart clouds there emerges bright
The radiance of the bow.
And as to things
Not mentioned here which of themselves do grow
Or of themselves are gendered, and all things
Which in the clouds condense to being- all,
Snow and the winds, hail and the hoar-frosts chill,
And freezing, mighty force- of lakes and pools
The mighty hardener, and mighty check
Which in the winter curbeth everywhere
The rivers as they go- 'tis easy still,
Soon to discover and with mind to see
How they all happen, whereby gendered,
When once thou well hast understood just what
Functions have been vouchsafed from of old
Unto the procreant atoms of the world.
