And so in first place, then
With thunder are shaken the blue deeps of heaven,
Because the ethereal clouds, scudding aloft,
Together clash, what time 'gainst one another
The winds are battling. For never a sound there come
From out the serene regions of the sky;
But wheresoever in a host more dense
The clouds foregather, thence more often comes
A crash with mighty rumbling. And, again,
Clouds cannot be of so condensed a frame
As stones and timbers, nor again so fine
As mists and flying smoke; for then perforce
They'd either fall, borne down by their brute weight,
Like stones, or, like the smoke, they'd powerless be
To keep their mass, or to retain within
Frore snows and storms of hail. And they give forth
O'er skiey levels of the spreading world
A sound on high, as linen-awning, stretched
O'er mighty theatres, gives forth at times
A cracking roar, when much 'tis beaten about
Betwixt the poles and cross-beams. Sometimes, too,
Asunder rent by wanton gusts, it raves
And imitates the tearing sound of sheets
Of paper- even this kind of noise thou mayst
In thunder hear- or sound as when winds whirl
With lashings and do buffet about in air
A hanging cloth and flying paper-sheets.
For sometimes, too, it chances that the clouds
Cannot together crash head-on, but rather
Move side-wise and with motions contrary
Graze each the other's body without speed,
From whence that dry sound grateth on our ears,
So long drawn-out, until the clouds have passed
From out their close positions.
And, again,
In following wise all things seem oft to quake
At shock of heavy thunder, and mightiest walls
Of the wide reaches of the upper world
There on the instant to have sprung apart,
Riven asunder, what time a gathered blast
Of the fierce hurricane hath all at once
Twisted its way into a mass of clouds,
And, there enclosed, ever more and more
Compelleth by its spinning whirl the cloud
To grow all hollow with a thickened crust
Surrounding; for thereafter, when the force
And the keen onset of the wind have weakened
That crust, lo, then the cloud, to-split in twain,
Gives forth a hideous crash with bang and boom.
No marvel this; since oft a bladder small,
Filled up with air, will, when of sudden burst,
Give forth a like large sound.
There's reason, too,
Why clouds make sounds, as through them blow the winds:
We see, borne down the sky, oft shapes of clouds
Rough-edged or branched many forky ways;
And 'tis the same, as when the sudden flaws
Of northwest wind through the dense forest blow,
Making the leaves to sough and limbs to crash.
It happens too at times that roused force
Of the fierce hurricane to-rends the cloud,
Breaking right through it by a front assault;
For what a blast of wind may do up there
Is manifest from facts when here on earth
A blast more gentle yet uptwists tall trees
And sucks them madly from their deepest roots.
Besides, among the clouds are waves, and these
Give, as they roughly break, a rumbling roar;
As when along deep streams or the great sea
Breaks the loud surf. It happens, too, whenever
Out from one cloud into another falls
The fiery energy of thunderbolt,
That straightaway the cloud, if full of wet,
Extinguishes the fire with mighty noise;
As iron, white from the hot furnaces,
Sizzles, when speedily we've plunged its glow
Down the cold water. Further, if a cloud
More dry receive the fire, 'twill suddenly
Kindle to flame and burn with monstrous sound,
As if a flame with whirl of winds should range
Along the laurel-tressed mountains far,
Upburning with its vast assault those trees;
Nor is there aught that in the crackling flame
Consumes with sound more terrible to man
Than Delphic laurel of Apollo lord.
Oft, too, the multitudinous crash of ice
And down-pour of swift hail gives forth a sound
Among the mighty clouds on high; for when
The wind hath packed them close, each mountain mass
Of rain-cloud, there congealed utterly
And mixed with hail-stones, breaks and booms…
Likewise, it lightens, when the clouds have struck,
By their collision, forth the seeds of fire:
As if a stone should smite a stone or steel,
For light then too leaps forth and fire then scatters
The shining sparks. But with our ears we get
The thunder after eyes behold the flash,
Because forever things arrive the ears
More tardily than the eyes- as thou mayst see
From this example too: when markest thou
Some man far yonder felling a great tree
With double-edged ax, it comes to pass
Thine eye beholds the swinging stroke before
The blow gives forth a sound athrough thine ears:
Thus also we behold the flashing ere
We hear the thunder, which discharged is
At same time with the fire and by same cause,
Born of the same collision.
In following wise
The clouds suffuse with leaping light the lands,
And the storm flashes with tremulous elan:
When the wind hath invaded a cloud, and, whirling there,
Hath wrought (as I have shown above) the cloud
Into a hollow with a thickened crust,
It becomes hot of own velocity:
Just as thou seest how motion will o'erheat
And set ablaze all objects- verily
A leaden ball, hurtling through length of space,
Even melts. Therefore, when this same wind a-fire
Hath split black cloud, it scatters the fire-seeds,
Which, so to say, have been pressed out by force
Of sudden from the cloud- and these do make
The pulsing flashes of flame; thence followeth
The detonation which attacks our ears
More tardily than aught which comes along
Unto the sight of eyeballs. This takes place-
As know thou mayst- at times when clouds are dense
And one upon the other piled aloft
With wonderful upheavings- nor be thou
Deceived because we see how broad their base
From underneath, and not how high they tower.
For make thine observations at a time
When winds shall bear athwart the horizon's blue
Clouds like to mountain-ranges moving on,
Or when about the sides of mighty peaks
Thou seest them one upon the other massed
And burdening downward, anchored in high repose,
With the winds sepulchred on all sides round:
Then canst thou know their mighty masses, then
Canst view their caverns, as if builded there
Of beetling crags; which, when the hurricanes
In gathered storm have filled utterly,
Then, prisoned in clouds, they rave around
With mighty roarings, and within those dens
Bluster like savage beasts, and now from here,
And now from there, send growlings through the clouds,
And seeking an outlet, whirl themselves about,
And roll from 'mid the clouds the seeds of fire,
And heap them multitudinously there,
And in the hollow furnaces within
Wheel flame around, until from bursted cloud
In forky flashes they have gleamed forth.
Again, from following cause it comes to pass
That yon swift golden hue of liquid fire
Darts downward to the earth: because the clouds
Themselves must hold abundant seeds of fire;
For, when they be without all moisture, then
They be for most part of a flamy hue
And a resplendent. And, indeed, they must
Even from the light of sun unto themselves
Take multitudinous seeds, and so perforce
Redden and pour their bright fires all abroad.
And therefore, when the wind hath driven and thrust,
Hath forced and squeezed into one spot these clouds,
They pour abroad the seeds of fire pressed out,
Which make to flash these colours of the flame.
Likewise, it lightens also when the clouds
Grow rare and thin along the sky; for, when
The wind with gentle touch unravels them
And breaketh asunder as they move, those seeds
Which make the lightnings must by nature fall;
At such an hour the horizon lightens round
Without the hideous terror of dread noise
And skiey uproar.
To proceed apace,
What sort of nature thunderbolts posses
Is by their strokes made manifest and by
The brand-marks of their searing heat on things,
And by the scorched scars exhaling round
The heavy fumes of sulphur. For all these
Are marks, O not of wind or rain, but fire.
Again, they often enkindle even the roofs
Of houses and inside the very rooms
With swift flame hold a fierce dominion.
Know thou that Nature fashioned this fire
Subtler than fires all other, with minute
And dartling bodies- a fire 'gainst which there's naught
Can in the least hold out: the thunderbolt,
The mighty, passes through the hedging walls
Of houses, like to voices or a shout-
Through stones, through bronze it passes, and it melts
Upon the instant bronze and gold; and makes,
Likewise, the wines sudden to vanish forth,
The wine-jars intact- because, ye see,
Its heat arriving renders loose and porous
Readily all the wine- jar's earthen sides,
And winding its way within, it scattereth
The elements primordial of the wine
With speedy dissolution- process which
Even in an age the fiery steam of sun
Could not accomplish, however puissant he
With his hot coruscations: so much more
Agile and overpowering is this force.
Now in what manner engendered are these things,
How fashioned of such impetuous strength
As to cleave towers asunder, and houses all
To overtopple, and to wrench apart
Timbers and beams, and heroes' monuments
To pile in ruins and upheave amain,
And to take breath forever out of men,
And to o'erthrow the cattle everywhere,-
Yes, by what force the lightnings do all this,
All this and more, I will unfold to thee,
Nor longer keep thee in mere promises.
The bolts of thunder, then, must be conceived
As all begotten in those crasser clouds
Up-piled aloft; for, from the sky serene
And from the clouds of lighter density,
None are sent forth forever. That 'tis so
Beyond a doubt, fact plain to sense declares:
To wit, at such a time the densed clouds
So mass themselves through all the upper air
That we might think that round about all murk
Had parted forth from Acheron and filled
The mighty vaults of sky- so grievously,
As gathers thus the storm-clouds' gruesome might,
Do faces of black horror hang on high-
When tempest begins its thunderbolts to forge.
Besides, full often also out at sea
A blackest thunderhead, like cataract
Of pitch hurled down from heaven, and far away
Bulging with murkiness, down on the waves
Falls with vast uproar, and draws on amain
The darkling tempests big with thunderbolts
And hurricanes, itself the while so crammed
Tremendously with fires and winds, that even
Back on the lands the people shudder round
And seek for cover. Therefore, as I said,
The storm must be conceived as o'er our head
Towering most high; for never would the clouds
O'erwhelm the lands with such a massy dark,
Unless up-builded heap on lofty heap,
To shut the round sun off. Nor could the clouds,
As on they come, engulf with rain so vast
As thus to make the rivers overflow
And fields to float, if ether were not thus
Furnished with lofty-piled clouds. Lo, then,
Here be all things fulfilled with winds and fires-
Hence the long lightnings and the thunders loud.
For, verily, I've taught thee even now
How cavernous clouds hold seeds innumerable
Of fiery exhalations, and they must
From off the sunbeams and the heat of these
Take many still. And so, when that same wind
(Which, haply, into one region of the sky
Collects those clouds) hath pressed from out the same
The many fiery seeds, and with that fire
Hath at the same time intermixed itself,
O then and there that wind, a whirlwind now,
Deep in the belly of the cloud spins round
In narrow confines, and sharpens there inside
In glowing furnaces the thunderbolt.
For in a two-fold manner is that wind
Enkindled all: it trembles into heat
Both by its own velocity and by
Repeated touch of fire. Thereafter, when
The energy of wind is heated through
And the fierce impulse of the fire hath sped
Deeply within, O then the thunderbolt,
Now ripened, so to say, doth suddenly
Splinter the cloud, and the aroused flash
Leaps onward, lumining with forky light
All places round. And followeth anon
A clap so heavy that the skiey vaults,
As if asunder burst, seem from on high
To engulf the earth. Then fearfully a quake
Pervades the lands, and 'long the lofty skies
Run the far rumblings. For at such a time
Nigh the whole tempest quakes, shook through and through,
And roused are the roarings- from which shock
Comes such resounding and abounding rain,
That all the murky ether seems to turn
Now into rain, and, as it tumbles down,
To summon the fields back to primeval floods:
So big the rains that be sent down on men
By burst of cloud and by the hurricane,
What time the thunder-clap, from burning bolt
That cracks the cloud, flies forth along. At times
The force of wind, excited from without,
Smiteth into a cloud already hot
With a ripe thunderbolt. And when that wind
Hath splintered that cloud, then down there cleaves forthwith
Yon fiery coil of flame which still we call,
Even with our fathers' word, a thunderbolt.
The same thing haps toward every other side
Whither that force hath swept. It happens, too,
That sometimes force of wind, though hurtled forth
Without all fire, yet in its voyage through space
Igniteth, whilst it comes along, along-
Losing some larger bodies which cannot
Pass, like the others, through the bulks of air-
And, scraping together out of air itself
Some smaller bodies, carries them along,
And these, commingling, by their flight make fire:
Much in the manner as oft a leaden ball
Grows hot upon its aery course, the while
It loseth many bodies of stark cold
And taketh into itself along the air
New particles of fire. It happens, too,
That force of blow itself arouses fire,
When force of wind, a-cold and hurtled forth
Without all fire, hath strook somewhere amain-
No marvel, because, when with terrific stroke
'Thas smitten, the elements of fiery-stuff
Can stream together from out the very wind
And, simultaneously, from out that thing
Which then and there receives the stroke: as flies
The fire when with the steel we hack the stone;
Nor yet, because the force of steel's a-cold,
Rush the less speedily together there
Under the stroke its seeds of radiance hot.
And therefore, thuswise must an object too
Be kindled by a thunderbolt, if haply
'Thas been adapt and suited to the flames.
Yet force of wind must not be rashly deemed
As altogether and entirely cold-
That force which is discharged from on high
With such stupendous power; but if 'tis not
Upon its course already kindled with fire,
It yet arriveth warmed and mixed with heat.
And, now, the speed and stroke of thunderbolt
Is so tremendous, and with glide so swift
Those thunderbolts rush on and down, because
Their roused force itself collects itself
First always in the clouds, and then prepares
For the huge effort of their going-forth;
Next, when the cloud no longer can retain
The increment of their fierce impetus,
Their force is pressed out, and therefore flies
With impetus so wondrous, like to shots
Hurled from the powerful Roman catapults.
Note, too, this force consists of elements
Both small and smooth, nor is there aught that can
With ease resist such nature. For it darts
Between and enters through the pores of things;
And so it never falters in delay
Despite innumerable collisions, but
Flies shooting onward with a swift elan.
Next, since by nature always every weight
Bears downward, doubled is the swiftness then
And that elan is still more wild and dread,
When, verily, to weight are added blows,
So that more madly and more fiercely then
The thunderbolt shakes into shivers all
That blocks its path, following on its way.
Then, too, because it comes along, along
With one continuing elan, it must
Take on velocity anew, anew,
Which still increases as it goes, and ever
Augments the bolt's vast powers and to the blow
Gives larger vigour; for it forces all,
All of the thunder's seeds of fire, to sweep
In a straight line unto one place, as 'twere,-
Casting them one by other, as they roll,
Into that onward course. Again, perchance,
In coming along, it pulls from out the air
Some certain bodies, which by their own blows
Enkindle its velocity. And, lo,
It comes through objects leaving them unharmed,
It goes through many things and leaves them whole,
Because the liquid fire flieth along
Athrough their pores. And much it does transfix,
When these primordial atoms of the bolt
Have fallen upon the atoms of these things
Precisely where the intertwined atoms
Are held together. And, further, easily
Brass it unbinds and quickly fuseth gold,
Because its force is so minutely made
Of tiny parts and elements so smooth
That easily they wind their way within,
And, when once in, quickly unbind all knots
And loosen all the bonds of union there.
And most in autumn is shaken the house of heaven,
The house so studded with the glittering stars,
And the whole earth around- most too in spring
When flowery times unfold themselves: for, lo,
In the cold season is there lack of fire,
And winds are scanty in the hot, and clouds
Have not so dense a bulk. But when, indeed,
The seasons of heaven are betwixt these twain,
The divers causes of the thunderbolt
Then all concur; for then both cold and heat
Are mixed in the cross-seas of the year,
So that a discord rises among things
And air in vast tumultuosity
Billows, infuriate with the fires and winds-
Of which the both are needed by the cloud
For fabrication of the thunderbolt.
For the first part of heat and last of cold
Is the time of spring; wherefore must things unlike
Do battle one with other, and, when mixed,
Tumultuously rage. And when rolls round
The latest heat mixed with the earliest chill-
The time which bears the name of autumn- then
Likewise fierce cold-spells wrestle with fierce heats.
On this account these seasons of the year
Are nominated "cross-seas."- And no marvel
If in those times the thunderbolts prevail
And storms are roused turbulent in heaven,
Since then both sides in dubious warfare rage
Tumultuously, the one with flames, the other
With winds and with waters mixed with winds.
This, this it is, O Memmius, to see through
The very nature of fire-fraught thunderbolt;
O this it is to mark by what blind force
It maketh each effect, and not, O not
To unwind Etrurian scrolls oracular,
Inquiring tokens of occult will of gods,
Even as to whence the flying flame hath come,
Or to which half of heaven it turns, or how
Through walled places it hath wound its way,
Or, after proving its dominion there,
How it hath speeded forth from thence amain,
Or what the thunderstroke portends of ill
From out high heaven. But if Jupiter
And other gods shake those refulgent vaults
With dread reverberations and hurl fire
Whither it pleases each, why smite they not
Mortals of reckless and revolting crimes,
That such may pant from a transpierced breast
Forth flames of the red levin- unto men
A drastic lesson?- why is rather he-
O he self-conscious of no foul offence-
Involved in flames, though innocent, and clasped
Up-caught in skiey whirlwind and in fire?
Nay, why, then, aim they at eternal wastes,
And spend themselves in vain?- perchance, even so
To exercise their arms and strengthen shoulders?
Why suffer they the Father's javelin
To be so blunted on the earth? And why
Doth he himself allow it, nor spare the same
Even for his enemies? O why most oft
Aims he at lofty places? Why behold we
Marks of his lightnings most on mountain tops?
Then for what reason shoots he at the sea?-
What sacrilege have waves and bulk of brine
And floating fields of foam been guilty of?
Besides, if 'tis his will that we beware
Against the lightning-stroke, why feareth he
To grant us power for to behold the shot?
And, contrariwise, if wills he to o'erwhelm us,
Quite off our guard, with fire, why thunders he
Off in yon quarter, so that we may shun?
Why rouseth he beforehand darkling air
And the far din and rumblings? And O how
Canst thou believe he shoots at one same time
Into diverse directions? Or darest thou
Contend that never hath it come to pass
That divers strokes have happened at one time?
But oft and often hath it come to pass,
And often still it must, that, even as showers
And rains o'er many regions fall, so too
Dart many thunderbolts at one same time.
Again, why never hurtles Jupiter
A bolt upon the lands nor pours abroad
Clap upon clap, when skies are cloudless all?
Or, say, doth he, so soon as ever the clouds
Have come thereunder, then into the same
Descend in person, and that from thence he may
Near-by decide upon the stroke of shaft?
And, lastly, why, with devastating bolt
Shakes he asunder holy shrines of gods
And his own thrones of splendour, and to-breaks
The well-wrought idols of divinities,
And robs of glory his own images
By wound of violence?
But to return apace,
Easy it is from these same facts to know
In just what wise those things (which from their sort
The Greeks have named "bellows") do come down,
Discharged from on high, upon the seas.
For it haps that sometimes from the sky descends
Upon the seas a column, as if pushed,
Round which the surges seethe, tremendously
Aroused by puffing gusts; and whatso'er
Of ships are caught within that tumult then
Come into extreme peril, dashed along.
This haps when sometimes wind's aroused force
Can't burst the cloud it tries to, but down-weighs
That cloud, until 'tis like a column from sky
Upon the seas pushed downward- gradually,
As if a Somewhat from on high were shoved
By fist and nether thrust of arm, and lengthened
Far to the waves. And when the force of wind
Hath rived this cloud, from out the cloud it rushes
Down on the seas, and starts among the waves
A wondrous seething, for the eddying whirl
Descends and downward draws along with it
That cloud of ductile body. And soon as ever
'Thas shoved unto the levels of the main
That laden cloud, the whirl suddenly then
Plunges its whole self into the waters there
And rouses all the sea with monstrous roar,
Constraining it to seethe. It happens too
That very vortex of the wind involves
Itself in clouds, scraping from out the air
The seeds of cloud, and counterfeits, as 'twere,
The "bellows" pushed from heaven. And when this shape
Hath dropped upon the lands and burst apart,
It belches forth immeasurable might
Of whirlwind and of blast. Yet since 'tis formed
At most but rarely, and on land the hills
Must block its way, 'tis seen more oft out there
On the broad prospect of the level main
Along the free horizons.
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.
Now come, and what the law of earthquakes is
Hearken, and first of all take care to know
That the under-earth, like to the earth around us,
Is full of windy caverns all about;
And many a pool and many a grim abyss
She bears within her bosom, ay, and cliffs
And jagged scarps; and many a river, hid
Beneath her chine, rolls rapidly along
Its billows and plunging boulders. For clear fact
Requires that earth must be in every part
Alike in constitution. Therefore, earth,
With these things underneath affixed and set,
Trembleth above, jarred by big down-tumblings,
When time hath undermined the huge caves,
The subterranean. Yea, whole mountains fall,
And instantly from spot of that big jar
There quiver the tremors far and wide abroad.
And with good reason: since houses on the street
Begin to quake throughout, when jarred by a cart
Of no large weight; and, too, the furniture
Within the house up-bounds, when a paving-block
Gives either iron rim of the wheels a jolt.
It happens, too, when some prodigious bulk
Of age-worn soil is rolled from mountain slopes
Into tremendous pools of water dark,
That the reeling land itself is rocked about
By the water's undulations; as a basin
Sometimes won't come to rest until the fluid
Within it ceases to be rocked about
In random undulations.
And besides,
When subterranean winds, up-gathered there
In the hollow deeps, bulk forward from one spot,
And press with the big urge of mighty powers
Against the lofty grottos, then the earth
Bulks to that quarter whither push amain
The headlong winds. Then all the builded houses
Above ground- and the more, the higher up-reared
Unto the sky- lean ominously, careening
Into the same direction; and the beams,
Wrenched forward, over-hang, ready to go.
Yet dread men to believe that there awaits
The nature of the mighty world a time
Of doom and cataclysm, albeit they see
So great a bulk of lands to bulge and break!
And lest the winds blew back again, no force
Could rein things in nor hold from sure career
On to disaster. But now because those winds
Blow back and forth in alternation strong,
And, so to say, rallying charge again,
And then repulsed retreat, on this account
Earth oftener threatens than she brings to pass
Collapses dire. For to one side she leans,
Then back she sways; and after tottering
Forward, recovers then her seats of poise.
Thus, this is why whole houses rock, the roofs
More than the middle stories, middle more
Than lowest, and the lowest least of all.
Arises, too, this same great earth-quaking,
When wind and some prodigious force of air,
Collected from without or down within
The old telluric deeps, have hurled themselves
Amain into those caverns sub-terrene,
And there at first tumultuously chafe
Among the vasty grottos, borne about
In mad rotations, till their lashed force
Aroused out-bursts abroad, and then and there,
Riving the deep earth, makes a mighty chasm-
What once in Syrian Sidon did befall,
And once in Peloponnesian Aegium,
Twain cities which such out-break of wild air
And earth's convulsion, following hard upon,
O'erthrew of old. And many a walled town,
Besides, hath fall'n by such omnipotent
Convulsions on the land, and in the sea
Engulfed hath sunken many a city down
With all its populace. But if, indeed,
They burst not forth, yet is the very rush
Of the wild air and fury-force of wind
Then dissipated, like an ague-fit,
Through the innumerable pores of earth,
To set her all a-shake- even as a chill,
When it hath gone into our marrow-bones,
Sets us convulsively, despite ourselves,
A-shivering and a-shaking. Therefore, men
With two-fold terror bustle in alarm
Through cities to and fro: they fear the roofs
Above the head; and underfoot they dread
The caverns, lest the nature of the earth
Suddenly rend them open, and she gape,
Herself asunder, with tremendous maw,
And, all confounded, seek to chock it full
With her own ruins. Let men, then, go on
Feigning at will that heaven and earth shall be
Inviolable, entrusted evermore
To an eternal weal: and yet at times
The very force of danger here at hand
Prods them on some side with this goad of fear-
This among others- that the earth, withdrawn
Abruptly from under their feet, be hurried down,
Down into the abyss, and the Sum-of-Things
Be following after, utterly fordone,
Till be but wrack and wreckage of a world.
With thunder are shaken the blue deeps of heaven,
Because the ethereal clouds, scudding aloft,
Together clash, what time 'gainst one another
The winds are battling. For never a sound there come
From out the serene regions of the sky;
But wheresoever in a host more dense
The clouds foregather, thence more often comes
A crash with mighty rumbling. And, again,
Clouds cannot be of so condensed a frame
As stones and timbers, nor again so fine
As mists and flying smoke; for then perforce
They'd either fall, borne down by their brute weight,
Like stones, or, like the smoke, they'd powerless be
To keep their mass, or to retain within
Frore snows and storms of hail. And they give forth
O'er skiey levels of the spreading world
A sound on high, as linen-awning, stretched
O'er mighty theatres, gives forth at times
A cracking roar, when much 'tis beaten about
Betwixt the poles and cross-beams. Sometimes, too,
Asunder rent by wanton gusts, it raves
And imitates the tearing sound of sheets
Of paper- even this kind of noise thou mayst
In thunder hear- or sound as when winds whirl
With lashings and do buffet about in air
A hanging cloth and flying paper-sheets.
For sometimes, too, it chances that the clouds
Cannot together crash head-on, but rather
Move side-wise and with motions contrary
Graze each the other's body without speed,
From whence that dry sound grateth on our ears,
So long drawn-out, until the clouds have passed
From out their close positions.
And, again,
In following wise all things seem oft to quake
At shock of heavy thunder, and mightiest walls
Of the wide reaches of the upper world
There on the instant to have sprung apart,
Riven asunder, what time a gathered blast
Of the fierce hurricane hath all at once
Twisted its way into a mass of clouds,
And, there enclosed, ever more and more
Compelleth by its spinning whirl the cloud
To grow all hollow with a thickened crust
Surrounding; for thereafter, when the force
And the keen onset of the wind have weakened
That crust, lo, then the cloud, to-split in twain,
Gives forth a hideous crash with bang and boom.
No marvel this; since oft a bladder small,
Filled up with air, will, when of sudden burst,
Give forth a like large sound.
There's reason, too,
Why clouds make sounds, as through them blow the winds:
We see, borne down the sky, oft shapes of clouds
Rough-edged or branched many forky ways;
And 'tis the same, as when the sudden flaws
Of northwest wind through the dense forest blow,
Making the leaves to sough and limbs to crash.
It happens too at times that roused force
Of the fierce hurricane to-rends the cloud,
Breaking right through it by a front assault;
For what a blast of wind may do up there
Is manifest from facts when here on earth
A blast more gentle yet uptwists tall trees
And sucks them madly from their deepest roots.
Besides, among the clouds are waves, and these
Give, as they roughly break, a rumbling roar;
As when along deep streams or the great sea
Breaks the loud surf. It happens, too, whenever
Out from one cloud into another falls
The fiery energy of thunderbolt,
That straightaway the cloud, if full of wet,
Extinguishes the fire with mighty noise;
As iron, white from the hot furnaces,
Sizzles, when speedily we've plunged its glow
Down the cold water. Further, if a cloud
More dry receive the fire, 'twill suddenly
Kindle to flame and burn with monstrous sound,
As if a flame with whirl of winds should range
Along the laurel-tressed mountains far,
Upburning with its vast assault those trees;
Nor is there aught that in the crackling flame
Consumes with sound more terrible to man
Than Delphic laurel of Apollo lord.
Oft, too, the multitudinous crash of ice
And down-pour of swift hail gives forth a sound
Among the mighty clouds on high; for when
The wind hath packed them close, each mountain mass
Of rain-cloud, there congealed utterly
And mixed with hail-stones, breaks and booms…
Likewise, it lightens, when the clouds have struck,
By their collision, forth the seeds of fire:
As if a stone should smite a stone or steel,
For light then too leaps forth and fire then scatters
The shining sparks. But with our ears we get
The thunder after eyes behold the flash,
Because forever things arrive the ears
More tardily than the eyes- as thou mayst see
From this example too: when markest thou
Some man far yonder felling a great tree
With double-edged ax, it comes to pass
Thine eye beholds the swinging stroke before
The blow gives forth a sound athrough thine ears:
Thus also we behold the flashing ere
We hear the thunder, which discharged is
At same time with the fire and by same cause,
Born of the same collision.
In following wise
The clouds suffuse with leaping light the lands,
And the storm flashes with tremulous elan:
When the wind hath invaded a cloud, and, whirling there,
Hath wrought (as I have shown above) the cloud
Into a hollow with a thickened crust,
It becomes hot of own velocity:
Just as thou seest how motion will o'erheat
And set ablaze all objects- verily
A leaden ball, hurtling through length of space,
Even melts. Therefore, when this same wind a-fire
Hath split black cloud, it scatters the fire-seeds,
Which, so to say, have been pressed out by force
Of sudden from the cloud- and these do make
The pulsing flashes of flame; thence followeth
The detonation which attacks our ears
More tardily than aught which comes along
Unto the sight of eyeballs. This takes place-
As know thou mayst- at times when clouds are dense
And one upon the other piled aloft
With wonderful upheavings- nor be thou
Deceived because we see how broad their base
From underneath, and not how high they tower.
For make thine observations at a time
When winds shall bear athwart the horizon's blue
Clouds like to mountain-ranges moving on,
Or when about the sides of mighty peaks
Thou seest them one upon the other massed
And burdening downward, anchored in high repose,
With the winds sepulchred on all sides round:
Then canst thou know their mighty masses, then
Canst view their caverns, as if builded there
Of beetling crags; which, when the hurricanes
In gathered storm have filled utterly,
Then, prisoned in clouds, they rave around
With mighty roarings, and within those dens
Bluster like savage beasts, and now from here,
And now from there, send growlings through the clouds,
And seeking an outlet, whirl themselves about,
And roll from 'mid the clouds the seeds of fire,
And heap them multitudinously there,
And in the hollow furnaces within
Wheel flame around, until from bursted cloud
In forky flashes they have gleamed forth.
Again, from following cause it comes to pass
That yon swift golden hue of liquid fire
Darts downward to the earth: because the clouds
Themselves must hold abundant seeds of fire;
For, when they be without all moisture, then
They be for most part of a flamy hue
And a resplendent. And, indeed, they must
Even from the light of sun unto themselves
Take multitudinous seeds, and so perforce
Redden and pour their bright fires all abroad.
And therefore, when the wind hath driven and thrust,
Hath forced and squeezed into one spot these clouds,
They pour abroad the seeds of fire pressed out,
Which make to flash these colours of the flame.
Likewise, it lightens also when the clouds
Grow rare and thin along the sky; for, when
The wind with gentle touch unravels them
And breaketh asunder as they move, those seeds
Which make the lightnings must by nature fall;
At such an hour the horizon lightens round
Without the hideous terror of dread noise
And skiey uproar.
To proceed apace,
What sort of nature thunderbolts posses
Is by their strokes made manifest and by
The brand-marks of their searing heat on things,
And by the scorched scars exhaling round
The heavy fumes of sulphur. For all these
Are marks, O not of wind or rain, but fire.
Again, they often enkindle even the roofs
Of houses and inside the very rooms
With swift flame hold a fierce dominion.
Know thou that Nature fashioned this fire
Subtler than fires all other, with minute
And dartling bodies- a fire 'gainst which there's naught
Can in the least hold out: the thunderbolt,
The mighty, passes through the hedging walls
Of houses, like to voices or a shout-
Through stones, through bronze it passes, and it melts
Upon the instant bronze and gold; and makes,
Likewise, the wines sudden to vanish forth,
The wine-jars intact- because, ye see,
Its heat arriving renders loose and porous
Readily all the wine- jar's earthen sides,
And winding its way within, it scattereth
The elements primordial of the wine
With speedy dissolution- process which
Even in an age the fiery steam of sun
Could not accomplish, however puissant he
With his hot coruscations: so much more
Agile and overpowering is this force.
Now in what manner engendered are these things,
How fashioned of such impetuous strength
As to cleave towers asunder, and houses all
To overtopple, and to wrench apart
Timbers and beams, and heroes' monuments
To pile in ruins and upheave amain,
And to take breath forever out of men,
And to o'erthrow the cattle everywhere,-
Yes, by what force the lightnings do all this,
All this and more, I will unfold to thee,
Nor longer keep thee in mere promises.
The bolts of thunder, then, must be conceived
As all begotten in those crasser clouds
Up-piled aloft; for, from the sky serene
And from the clouds of lighter density,
None are sent forth forever. That 'tis so
Beyond a doubt, fact plain to sense declares:
To wit, at such a time the densed clouds
So mass themselves through all the upper air
That we might think that round about all murk
Had parted forth from Acheron and filled
The mighty vaults of sky- so grievously,
As gathers thus the storm-clouds' gruesome might,
Do faces of black horror hang on high-
When tempest begins its thunderbolts to forge.
Besides, full often also out at sea
A blackest thunderhead, like cataract
Of pitch hurled down from heaven, and far away
Bulging with murkiness, down on the waves
Falls with vast uproar, and draws on amain
The darkling tempests big with thunderbolts
And hurricanes, itself the while so crammed
Tremendously with fires and winds, that even
Back on the lands the people shudder round
And seek for cover. Therefore, as I said,
The storm must be conceived as o'er our head
Towering most high; for never would the clouds
O'erwhelm the lands with such a massy dark,
Unless up-builded heap on lofty heap,
To shut the round sun off. Nor could the clouds,
As on they come, engulf with rain so vast
As thus to make the rivers overflow
And fields to float, if ether were not thus
Furnished with lofty-piled clouds. Lo, then,
Here be all things fulfilled with winds and fires-
Hence the long lightnings and the thunders loud.
For, verily, I've taught thee even now
How cavernous clouds hold seeds innumerable
Of fiery exhalations, and they must
From off the sunbeams and the heat of these
Take many still. And so, when that same wind
(Which, haply, into one region of the sky
Collects those clouds) hath pressed from out the same
The many fiery seeds, and with that fire
Hath at the same time intermixed itself,
O then and there that wind, a whirlwind now,
Deep in the belly of the cloud spins round
In narrow confines, and sharpens there inside
In glowing furnaces the thunderbolt.
For in a two-fold manner is that wind
Enkindled all: it trembles into heat
Both by its own velocity and by
Repeated touch of fire. Thereafter, when
The energy of wind is heated through
And the fierce impulse of the fire hath sped
Deeply within, O then the thunderbolt,
Now ripened, so to say, doth suddenly
Splinter the cloud, and the aroused flash
Leaps onward, lumining with forky light
All places round. And followeth anon
A clap so heavy that the skiey vaults,
As if asunder burst, seem from on high
To engulf the earth. Then fearfully a quake
Pervades the lands, and 'long the lofty skies
Run the far rumblings. For at such a time
Nigh the whole tempest quakes, shook through and through,
And roused are the roarings- from which shock
Comes such resounding and abounding rain,
That all the murky ether seems to turn
Now into rain, and, as it tumbles down,
To summon the fields back to primeval floods:
So big the rains that be sent down on men
By burst of cloud and by the hurricane,
What time the thunder-clap, from burning bolt
That cracks the cloud, flies forth along. At times
The force of wind, excited from without,
Smiteth into a cloud already hot
With a ripe thunderbolt. And when that wind
Hath splintered that cloud, then down there cleaves forthwith
Yon fiery coil of flame which still we call,
Even with our fathers' word, a thunderbolt.
The same thing haps toward every other side
Whither that force hath swept. It happens, too,
That sometimes force of wind, though hurtled forth
Without all fire, yet in its voyage through space
Igniteth, whilst it comes along, along-
Losing some larger bodies which cannot
Pass, like the others, through the bulks of air-
And, scraping together out of air itself
Some smaller bodies, carries them along,
And these, commingling, by their flight make fire:
Much in the manner as oft a leaden ball
Grows hot upon its aery course, the while
It loseth many bodies of stark cold
And taketh into itself along the air
New particles of fire. It happens, too,
That force of blow itself arouses fire,
When force of wind, a-cold and hurtled forth
Without all fire, hath strook somewhere amain-
No marvel, because, when with terrific stroke
'Thas smitten, the elements of fiery-stuff
Can stream together from out the very wind
And, simultaneously, from out that thing
Which then and there receives the stroke: as flies
The fire when with the steel we hack the stone;
Nor yet, because the force of steel's a-cold,
Rush the less speedily together there
Under the stroke its seeds of radiance hot.
And therefore, thuswise must an object too
Be kindled by a thunderbolt, if haply
'Thas been adapt and suited to the flames.
Yet force of wind must not be rashly deemed
As altogether and entirely cold-
That force which is discharged from on high
With such stupendous power; but if 'tis not
Upon its course already kindled with fire,
It yet arriveth warmed and mixed with heat.
And, now, the speed and stroke of thunderbolt
Is so tremendous, and with glide so swift
Those thunderbolts rush on and down, because
Their roused force itself collects itself
First always in the clouds, and then prepares
For the huge effort of their going-forth;
Next, when the cloud no longer can retain
The increment of their fierce impetus,
Their force is pressed out, and therefore flies
With impetus so wondrous, like to shots
Hurled from the powerful Roman catapults.
Note, too, this force consists of elements
Both small and smooth, nor is there aught that can
With ease resist such nature. For it darts
Between and enters through the pores of things;
And so it never falters in delay
Despite innumerable collisions, but
Flies shooting onward with a swift elan.
Next, since by nature always every weight
Bears downward, doubled is the swiftness then
And that elan is still more wild and dread,
When, verily, to weight are added blows,
So that more madly and more fiercely then
The thunderbolt shakes into shivers all
That blocks its path, following on its way.
Then, too, because it comes along, along
With one continuing elan, it must
Take on velocity anew, anew,
Which still increases as it goes, and ever
Augments the bolt's vast powers and to the blow
Gives larger vigour; for it forces all,
All of the thunder's seeds of fire, to sweep
In a straight line unto one place, as 'twere,-
Casting them one by other, as they roll,
Into that onward course. Again, perchance,
In coming along, it pulls from out the air
Some certain bodies, which by their own blows
Enkindle its velocity. And, lo,
It comes through objects leaving them unharmed,
It goes through many things and leaves them whole,
Because the liquid fire flieth along
Athrough their pores. And much it does transfix,
When these primordial atoms of the bolt
Have fallen upon the atoms of these things
Precisely where the intertwined atoms
Are held together. And, further, easily
Brass it unbinds and quickly fuseth gold,
Because its force is so minutely made
Of tiny parts and elements so smooth
That easily they wind their way within,
And, when once in, quickly unbind all knots
And loosen all the bonds of union there.
And most in autumn is shaken the house of heaven,
The house so studded with the glittering stars,
And the whole earth around- most too in spring
When flowery times unfold themselves: for, lo,
In the cold season is there lack of fire,
And winds are scanty in the hot, and clouds
Have not so dense a bulk. But when, indeed,
The seasons of heaven are betwixt these twain,
The divers causes of the thunderbolt
Then all concur; for then both cold and heat
Are mixed in the cross-seas of the year,
So that a discord rises among things
And air in vast tumultuosity
Billows, infuriate with the fires and winds-
Of which the both are needed by the cloud
For fabrication of the thunderbolt.
For the first part of heat and last of cold
Is the time of spring; wherefore must things unlike
Do battle one with other, and, when mixed,
Tumultuously rage. And when rolls round
The latest heat mixed with the earliest chill-
The time which bears the name of autumn- then
Likewise fierce cold-spells wrestle with fierce heats.
On this account these seasons of the year
Are nominated "cross-seas."- And no marvel
If in those times the thunderbolts prevail
And storms are roused turbulent in heaven,
Since then both sides in dubious warfare rage
Tumultuously, the one with flames, the other
With winds and with waters mixed with winds.
This, this it is, O Memmius, to see through
The very nature of fire-fraught thunderbolt;
O this it is to mark by what blind force
It maketh each effect, and not, O not
To unwind Etrurian scrolls oracular,
Inquiring tokens of occult will of gods,
Even as to whence the flying flame hath come,
Or to which half of heaven it turns, or how
Through walled places it hath wound its way,
Or, after proving its dominion there,
How it hath speeded forth from thence amain,
Or what the thunderstroke portends of ill
From out high heaven. But if Jupiter
And other gods shake those refulgent vaults
With dread reverberations and hurl fire
Whither it pleases each, why smite they not
Mortals of reckless and revolting crimes,
That such may pant from a transpierced breast
Forth flames of the red levin- unto men
A drastic lesson?- why is rather he-
O he self-conscious of no foul offence-
Involved in flames, though innocent, and clasped
Up-caught in skiey whirlwind and in fire?
Nay, why, then, aim they at eternal wastes,
And spend themselves in vain?- perchance, even so
To exercise their arms and strengthen shoulders?
Why suffer they the Father's javelin
To be so blunted on the earth? And why
Doth he himself allow it, nor spare the same
Even for his enemies? O why most oft
Aims he at lofty places? Why behold we
Marks of his lightnings most on mountain tops?
Then for what reason shoots he at the sea?-
What sacrilege have waves and bulk of brine
And floating fields of foam been guilty of?
Besides, if 'tis his will that we beware
Against the lightning-stroke, why feareth he
To grant us power for to behold the shot?
And, contrariwise, if wills he to o'erwhelm us,
Quite off our guard, with fire, why thunders he
Off in yon quarter, so that we may shun?
Why rouseth he beforehand darkling air
And the far din and rumblings? And O how
Canst thou believe he shoots at one same time
Into diverse directions? Or darest thou
Contend that never hath it come to pass
That divers strokes have happened at one time?
But oft and often hath it come to pass,
And often still it must, that, even as showers
And rains o'er many regions fall, so too
Dart many thunderbolts at one same time.
Again, why never hurtles Jupiter
A bolt upon the lands nor pours abroad
Clap upon clap, when skies are cloudless all?
Or, say, doth he, so soon as ever the clouds
Have come thereunder, then into the same
Descend in person, and that from thence he may
Near-by decide upon the stroke of shaft?
And, lastly, why, with devastating bolt
Shakes he asunder holy shrines of gods
And his own thrones of splendour, and to-breaks
The well-wrought idols of divinities,
And robs of glory his own images
By wound of violence?
But to return apace,
Easy it is from these same facts to know
In just what wise those things (which from their sort
The Greeks have named "bellows") do come down,
Discharged from on high, upon the seas.
For it haps that sometimes from the sky descends
Upon the seas a column, as if pushed,
Round which the surges seethe, tremendously
Aroused by puffing gusts; and whatso'er
Of ships are caught within that tumult then
Come into extreme peril, dashed along.
This haps when sometimes wind's aroused force
Can't burst the cloud it tries to, but down-weighs
That cloud, until 'tis like a column from sky
Upon the seas pushed downward- gradually,
As if a Somewhat from on high were shoved
By fist and nether thrust of arm, and lengthened
Far to the waves. And when the force of wind
Hath rived this cloud, from out the cloud it rushes
Down on the seas, and starts among the waves
A wondrous seething, for the eddying whirl
Descends and downward draws along with it
That cloud of ductile body. And soon as ever
'Thas shoved unto the levels of the main
That laden cloud, the whirl suddenly then
Plunges its whole self into the waters there
And rouses all the sea with monstrous roar,
Constraining it to seethe. It happens too
That very vortex of the wind involves
Itself in clouds, scraping from out the air
The seeds of cloud, and counterfeits, as 'twere,
The "bellows" pushed from heaven. And when this shape
Hath dropped upon the lands and burst apart,
It belches forth immeasurable might
Of whirlwind and of blast. Yet since 'tis formed
At most but rarely, and on land the hills
Must block its way, 'tis seen more oft out there
On the broad prospect of the level main
Along the free horizons.
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.
Now come, and what the law of earthquakes is
Hearken, and first of all take care to know
That the under-earth, like to the earth around us,
Is full of windy caverns all about;
And many a pool and many a grim abyss
She bears within her bosom, ay, and cliffs
And jagged scarps; and many a river, hid
Beneath her chine, rolls rapidly along
Its billows and plunging boulders. For clear fact
Requires that earth must be in every part
Alike in constitution. Therefore, earth,
With these things underneath affixed and set,
Trembleth above, jarred by big down-tumblings,
When time hath undermined the huge caves,
The subterranean. Yea, whole mountains fall,
And instantly from spot of that big jar
There quiver the tremors far and wide abroad.
And with good reason: since houses on the street
Begin to quake throughout, when jarred by a cart
Of no large weight; and, too, the furniture
Within the house up-bounds, when a paving-block
Gives either iron rim of the wheels a jolt.
It happens, too, when some prodigious bulk
Of age-worn soil is rolled from mountain slopes
Into tremendous pools of water dark,
That the reeling land itself is rocked about
By the water's undulations; as a basin
Sometimes won't come to rest until the fluid
Within it ceases to be rocked about
In random undulations.
And besides,
When subterranean winds, up-gathered there
In the hollow deeps, bulk forward from one spot,
And press with the big urge of mighty powers
Against the lofty grottos, then the earth
Bulks to that quarter whither push amain
The headlong winds. Then all the builded houses
Above ground- and the more, the higher up-reared
Unto the sky- lean ominously, careening
Into the same direction; and the beams,
Wrenched forward, over-hang, ready to go.
Yet dread men to believe that there awaits
The nature of the mighty world a time
Of doom and cataclysm, albeit they see
So great a bulk of lands to bulge and break!
And lest the winds blew back again, no force
Could rein things in nor hold from sure career
On to disaster. But now because those winds
Blow back and forth in alternation strong,
And, so to say, rallying charge again,
And then repulsed retreat, on this account
Earth oftener threatens than she brings to pass
Collapses dire. For to one side she leans,
Then back she sways; and after tottering
Forward, recovers then her seats of poise.
Thus, this is why whole houses rock, the roofs
More than the middle stories, middle more
Than lowest, and the lowest least of all.
Arises, too, this same great earth-quaking,
When wind and some prodigious force of air,
Collected from without or down within
The old telluric deeps, have hurled themselves
Amain into those caverns sub-terrene,
And there at first tumultuously chafe
Among the vasty grottos, borne about
In mad rotations, till their lashed force
Aroused out-bursts abroad, and then and there,
Riving the deep earth, makes a mighty chasm-
What once in Syrian Sidon did befall,
And once in Peloponnesian Aegium,
Twain cities which such out-break of wild air
And earth's convulsion, following hard upon,
O'erthrew of old. And many a walled town,
Besides, hath fall'n by such omnipotent
Convulsions on the land, and in the sea
Engulfed hath sunken many a city down
With all its populace. But if, indeed,
They burst not forth, yet is the very rush
Of the wild air and fury-force of wind
Then dissipated, like an ague-fit,
Through the innumerable pores of earth,
To set her all a-shake- even as a chill,
When it hath gone into our marrow-bones,
Sets us convulsively, despite ourselves,
A-shivering and a-shaking. Therefore, men
With two-fold terror bustle in alarm
Through cities to and fro: they fear the roofs
Above the head; and underfoot they dread
The caverns, lest the nature of the earth
Suddenly rend them open, and she gape,
Herself asunder, with tremendous maw,
And, all confounded, seek to chock it full
With her own ruins. Let men, then, go on
Feigning at will that heaven and earth shall be
Inviolable, entrusted evermore
To an eternal weal: and yet at times
The very force of danger here at hand
Prods them on some side with this goad of fear-
This among others- that the earth, withdrawn
Abruptly from under their feet, be hurried down,
Down into the abyss, and the Sum-of-Things
Be following after, utterly fordone,
Till be but wrack and wreckage of a world.
