De Rerum Natura

Lucretius

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

O humankind unhappy!- when it ascribed
Unto divinities such awesome deeds,
And coupled thereto rigours of fierce wrath!
What groans did men on that sad day beget
Even for themselves, and O what wounds for us,
What tears for our children's children! Nor, O man,
Is thy true piety in this: with head
Under the veil, still to be seen to turn
Fronting a stone, and ever to approach
Unto all altars; nor so prone on earth
Forward to fall, to spread upturned palms
Before the shrines of gods, nor yet to dew
Altars with profuse blood of four-foot beasts,
Nor vows with vows to link. But rather this:
To look on all things with a master eye
And mind at peace. For when we gaze aloft
Upon the skiey vaults of yon great world
And ether, fixed high o'er twinkling stars,
And into our thought there come the journeyings
Of sun and moon, O then into our breasts,
O'erburdened already with their other ills,
Begins forthwith to rear its sudden head
One more misgiving: lest o'er us, percase,
It be the gods' immeasurable power
That rolls, with varied motion, round and round
The far white constellations. For the lack
Of aught of reasons tries the puzzled mind:
Whether was ever a birth-time of the world,
And whether, likewise, any end shall be
How far the ramparts of the world can still
Outstand this strain of ever-roused motion,
Or whether, divinely with eternal weal
Endowed, they can through endless tracts of age
Glide on, defying the o'er-mighty powers
Of the immeasurable ages. Lo,
What man is there whose mind with dread of gods
Cringes not close, whose limbs with terror-spell
Crouch not together, when the parched earth
Quakes with the horrible thunderbolt amain,
And across the mighty sky the rumblings run?
Do not the peoples and the nations shake,
And haughty kings do they not hug their limbs,
Strook through with fear of the divinities,
Lest for aught foully done or madly said
The heavy time be now at hand to pay?
When, too, fierce force of fury-winds at sea
Sweepeth a navy's admiral down the main
With his stout legions and his elephants,
Doth he not seek the peace of gods with vows,
And beg in prayer, a-tremble, lulled winds
And friendly gales?- in vain, since, often up-caught
In fury-cyclones, is he borne along,
For all his mouthings, to the shoals of doom.
Ah, so irrevocably some hidden power
Betramples forevermore affairs of men,
And visibly grindeth with its heel in mire
The lictors' glorious rods and axes dire,
Having them in derision! Again, when earth
From end to end is rocking under foot,
And shaken cities ruin down, or threaten
Upon the verge, what wonder is it then
That mortal generations abase themselves,
And unto gods in all affairs of earth
Assign as last resort almighty powers
And wondrous energies to govern all?

Now for the rest: copper and gold and iron
Discovered were, and with them silver's weight
And power of lead, when with prodigious heat
The conflagrations burned the forest trees
Among the mighty mountains, by a bolt
Of lightning from the sky, or else because
Men, warring in the woodlands, on their foes
Had hurled fire to frighten and dismay,
Or yet because, by goodness of the soil
Invited, men desired to clear rich fields
And turn the countryside to pasture-lands,
Or slay the wild and thrive upon the spoils.
(For hunting by pit-fall and by fire arose
Before the art of hedging the covert round
With net or stirring it with dogs of chase.)
Howso the fact, and from what cause soever
The flamy heat with awful crack and roar
Had there devoured to their deepest roots
The forest trees and baked the earth with fire,
Then from the boiling veins began to ooze
O rivulets of silver and of gold,
Of lead and copper too, collecting soon
Into the hollow places of the ground.
And when men saw the cooled lumps anon
To shine with splendour-sheen upon the ground,
Much taken with that lustrous smooth delight,
They 'gan to pry them out, and saw how each
Had got a shape like to its earthy mould.
Then would it enter their heads how these same lumps,
If melted by heat, could into any form
Or figure of things be run, and how, again,
If hammered out, they could be nicely drawn
To sharpest points or finest edge, and thus
Yield to the forgers tools and give them power
To chop the forest down, to hew the logs,
To shave the beams and planks, besides to bore
And punch and drill. And men began such work
At first as much with tools of silver and gold
As with the impetuous strength of the stout copper;
But vainly- since their over-mastered power
Would soon give way, unable to endure,
Like copper, such hard labour. In those days
Copper it was that was the thing of price;
And gold lay useless, blunted with dull edge.
Now lies the copper low, and gold hath come
Unto the loftiest honours. Thus it is
That rolling ages change the times of things:
What erst was of a price, becomes at last
A discard of no honour; whilst another
Succeeds to glory, issuing from contempt,
And day by day is sought for more and more,
And, when 'tis found, doth flower in men's praise,
Objects of wondrous honour.

Now, Memmius,
How nature of iron discovered was, thou mayst
Of thine own self divine. Man's ancient arms
Were hands, and nails and teeth, stones too and boughs-
Breakage of forest trees- and flame and fire,
As soon as known. Thereafter force of iron
And copper discovered was; and copper's use
Was known ere iron's, since more tractable
Its nature is and its abundance more.
With copper men to work the soil began,
With copper to rouse the hurly waves of war,
To straw the monstrous wounds, and seize away
Another's flocks and fields. For unto them,
Thus armed, all things naked of defence
Readily yielded. Then by slow degrees
The sword of iron succeeded, and the shape
Of brazen sickle into scorn was turned:
With iron to cleave the soil of earth they 'gan,
And the contentions of uncertain war
Were rendered equal.
And, lo, man was wont
Armed to mount upon the ribs of horse
And guide him with the rein, and play about
With right hand free, oft times before he tried
Perils of war in yoked chariot;
And yoked pairs abreast came earlier
Than yokes of four, or scythed chariots
Whereinto clomb the men-at-arms. And next
The Punic folk did train the elephants-
Those curst Lucanian oxen, hideous,
The serpent-handed, with turrets on their bulks-
To dure the wounds of war and panic-strike
The mighty troops of Mars. Thus Discord sad
Begat the one Thing after other, to be
The terror of the nations under arms,
And day by day to horrors of old war
She added an increase.

Bulls, too, they tried
In war's grim business; and essayed to send
Outrageous boars against the foes. And some
Sent on before their ranks puissant lions
With armed trainers and with masters fierce
To guide and hold in chains- and yet in vain,
Since fleshed with pell-mell slaughter, fierce they flew,
And blindly through the squadrons havoc wrought,
Shaking the frightful crests upon their heads,
Now here, now there. Nor could the horsemen calm
Their horses, panic-breasted at the roar,
And rein them round to front the foe. With spring
The infuriate she-lions would up-leap
Now here, now there; and whoso came apace
Against them, these they'd rend across the face;
And others unwitting from behind they'd tear
Down from their mounts, and twining round them, bring
Tumbling to earth, o'ermastered by the wound,
And with those powerful fangs and hooked claws
Fasten upon them. Bulls would toss their friends,
And trample under foot, and from beneath
Rip flanks and bellies of horses with their horns,
And with a threat'ning forehead jam the sod;
And boars would gore with stout tusks their allies,
Splashing in fury their own blood on spears
Splintered in their own bodies, and would fell
In rout and ruin infantry and horse.
For there the beasts-of-saddle tried to scape
The savage thrusts of tusk by shying off,
Or rearing up with hoofs a-paw in air.
In vain- since there thou mightest see them sink,
Their sinews severed, and with heavy fall
Bestrew the ground. And such of these as men
Supposed well-trained long ago at home,
Were in the thick of action seen to foam
In fury, from the wounds, the shrieks, the flight,
The panic, and the tumult; nor could men
Aught of their numbers rally. For each breed
And various of the wild beasts fled apart
Hither or thither, as often in wars to-day
Flee those Lucanian oxen, by the steel
Grievously mangled, after they have wrought
Upon their friends so many a dreadful doom.
(If 'twas, indeed, that thus they did at all:
But scarcely I'll believe that men could not
With mind foreknow and see, as sure to come,
Such foul and general disaster.- This
We, then, may hold as true in the great All,
In divers worlds on divers plan create,-
Somewhere afar more likely than upon
One certain earth.) But men chose this to do
Less in the hope of conquering than to give
Their enemies a goodly cause of woe,
Even though thereby they perished themselves,
Since weak in numbers and since wanting arms.

Now, clothes of roughly inter-plaited strands
Were earlier than loom-wove coverings;
The loom-wove later than man's iron is,
Since iron is needful in the weaving art,
Nor by no other means can there be wrought
Such polished tools- the treadles, spindles, shuttles,
And sounding yarn-beams. And nature forced the men,
Before the woman kind, to work the wool:
For all the male kind far excels in skill,
And cleverer is by much- until at last
The rugged farmer folk jeered at such tasks,
And so were eager soon to give them o'er
To women's hands, and in more hardy toil
To harden arms and hands.

But nature herself,
Mother of things, was the first seed-sower
And primal grafter; since the berries and acorns,
Dropping from off the trees, would there beneath
Put forth in season swarms of little shoots;
Hence too men's fondness for ingrafting slips
Upon the boughs and setting out in holes
The young shrubs o'er the fields. Then would they try
Ever new modes of tilling their loved crofts,
And mark they would how earth improved the taste
Of the wild fruits by fond and fostering care.
And day by day they'd force the woods to move
Still higher up the mountain, and to yield
The place below for tilth, that there they might,
On plains and uplands, have their meadow-plats,
Cisterns and runnels, crops of standing grain,
And happy vineyards, and that all along
O'er hillocks, intervales, and plains might run
The silvery-green belt of olive-trees,
Marking the plotted landscape; even as now
Thou seest so marked with varied loveliness
All the terrain which men adorn and plant
With rows of goodly fruit-trees and hedge round
With thriving shrubberies sown.

But by the mouth
To imitate the liquid notes of birds
Was earlier far 'mongst men than power to make,
By measured song, melodious verse and give
Delight to ears. And whistlings of the wind
Athrough the hollows of the reeds first taught
The peasantry to blow into the stalks
Of hollow hemlock-herb. Then bit by bit
They learned sweet plainings, such as pipe out-pours,
Beaten by finger-tips of singing men,
When heard through unpathed groves and forest deeps
And woodsy meadows, through the untrod haunts
Of shepherd folk and spots divinely still.
Thus time draws forward each and everything
Little by little unto the midst of men,
And reason uplifts it to the shores of light.
These tunes would soothe and glad the minds of mortals
When sated with food,- for songs are welcome then.
And often, lounging with friends in the soft grass
Beside a river of water, underneath
A big tree's branches, merrily they'd refresh
Their frames, with no vast outlay- most of all
If the weather were smiling and the times of the year
Were painting the green of the grass around with flowers.
Then jokes, then talk, then peals of jollity
Would circle round; for then the rustic muse
Was in her glory; then would antic Mirth
Prompt them to garland head and shoulders about
With chaplets of intertwined flowers and leaves,
And to dance onward, out of tune, with limbs
Clownishly swaying, and with clownish foot
To beat our mother earth- from whence arose
Laughter and peals of jollity, for, lo,
Such frolic acts were in their glory then,
Being more new and strange. And wakeful men
Found solaces for their unsleeping hours
In drawing forth variety of notes,
In modulating melodies, in running
With puckered lips along the tuned reeds,
Whence, even in our day do the watchmen guard
These old traditions, and have learned well
To keep true measure. And yet they no whit
Do get a larger fruit of gladsomeness
Than got the woodland aborigines
In olden times. For what we have at hand-
If theretofore naught sweeter we have known-
That chiefly pleases and seems best of all;
But then some later, likely better, find
Destroys its worth and changes our desires
Regarding good of yesterday.

And thus
Began the loathing of the acorn; thus
Abandoned were those beds with grasses strewn
And with the leaves beladen. Thus, again,
Fell into new contempt the pelts of beasts-
Erstwhile a robe of honour, which, I guess,
Aroused in those days envy so malign
That the first wearer went to woeful death
By ambuscades,- and yet that hairy prize,
Rent into rags by greedy foemen there
And splashed by blood, was ruined utterly
Beyond all use or vantage. Thus of old
'Twas pelts, and of to-day 'tis purple and gold
That cark men's lives with cares and weary with war.
Wherefore, methinks, resides the greater blame
With us vain men to-day: for cold would rack,
Without their pelts, the naked sons of earth;
But us it nothing hurts to do without
The purple vestment, broidered with gold
And with imposing figures, if we still
Make shift with some mean garment of the Plebs.
So man in vain futilities toils on
Forever and wastes in idle cares his years-
Because, of very truth, he hath not learnt
What the true end of getting is, nor yet
At all how far true pleasure may increase.
And 'tis desire for better and for more
Hath carried by degrees mortality
Out onward to the deep, and roused up
From the far bottom mighty waves of war.

But sun and moon, those watchmen of the world,
With their own lanterns traversing around
The mighty, the revolving vault, have taught
Unto mankind that seasons of the years
Return again, and that the Thing takes place
After a fixed plan and order fixed.
Already would they pass their life, hedged round
By the strong towers; and cultivate an earth
All portioned out and boundaried; already
Would the sea flower and sail-winged ships;
Already men had, under treaty pacts,
Confederates and allies, when poets began
To hand heroic actions down in verse;
Nor long ere this had letters been devised-
Hence is our age unable to look back
On what has gone before, except where reason
Shows us a footprint.
Sailings on the seas,
Tillings of fields, walls, laws, and arms, and roads,
Dress and the like, all prizes, all delights
Of finer life, poems, pictures, chiselled shapes
Of polished sculptures- all these arts were learned
By practice and the mind's experience,
As men walked forward step by eager step.
Thus time draws forward each and everything
Little by little into the midst of men,
And reason uplifts it to the shores of light.
For one thing after other did men see
Grow clear by intellect, till with their arts
They've now achieved the supreme pinnacle.

'Twas Athens first, the glorious in name,
That whilom gave to hapless sons of men
The sheaves of harvest, and re-ordered life,
And decreed laws; and she the first that gave
Life its sweet solaces, when she begat
A man of heart so wise, who whilom poured
All wisdom forth from his truth-speaking mouth;
The glory of whom, though dead, is yet to-day,
Because of those discoveries divine
Renowned of old, exalted to the sky.
For when saw he that well-nigh everything
Which needs of man most urgently require
Was ready to hand for mortals, and that life,
As far as might be, was established safe,
That men were lords in riches, honour, praise,
And eminent in goodly fame of sons,
And that they yet, O yet, within the home,
Still had the anxious heart which vexed life
Unpausingly with torments of the mind,
And raved perforce with angry plaints, then he,
Then he, the master, did perceive that 'twas
The vessel itself which worked the bane, and all,
However wholesome, which from here or there
Was gathered into it, was by that bane
Spoilt from within,- in part, because he saw
The vessel so cracked and leaky that nowise
'T could ever be filled to brim; in part because
He marked how it polluted with foul taste
Whate'er it got within itself. So he,
The master, then by his truth-speaking words,
Purged the breasts of men, and set the bounds
Of lust and terror, and exhibited
The supreme good whither we all endeavour,
And showed the path whereby we might arrive
Thereunto by a little cross-cut straight,
And what of ills in all affairs of mortals
Upsprang and flitted deviously about
(Whether by chance or force), since nature thus
Had destined; and from out what gates a man
Should sally to each combat. And he proved
That mostly vainly doth the human race
Roll in its bosom the grim waves of care.
For just as children tremble and fear all
In the viewless dark, so even we at times
Dread in the light so many things that be
No whit more fearsome than what children feign,
Shuddering, will be upon them in the dark.
This terror then, this darkness of the mind,
Not sunrise with its flaring spokes of light,
Nor glittering arrows of morning can disperse,
But only nature's aspect and her law.
Wherefore the more will I go on to weave
In verses this my undertaken task.

And since I've taught thee that the world's great vaults
Are mortal and that sky is fashioned
Of frame e'en born in time, and whatsoe'er
Therein go on and must perforce go on
. . . . . .
The most I have unravelled; what remains
Do thou take in, besides; since once for all
To climb into that chariot' renowned
. . . . . .
Of winds arise; and they appeased are
So that all things again...
. . . . . .
Which were, are changed now, with fury stilled;
All other movements through the earth and sky
Which mortals gaze upon (O anxious oft
In quaking thoughts!), and which abase their minds
With dread of deities and press them crushed
Down to the earth, because their ignorance
Of cosmic causes forces them to yield
All things unto the empery of gods
And to concede the kingly rule to them.
For even those men who have learned full well
That godheads lead a long life free of care,
If yet meanwhile they wonder by what plan
Things can go on (and chiefly yon high things
Observed o'erhead on the ethereal coasts),
Again are hurried back unto the fears
Of old religion and adopt again
Harsh masters, deemed almighty,- wretched men,
Unwitting what can be and what cannot,
And by what law to each its scope prescribed,
Its boundary stone that clings so deep in Time.
Wherefore the more are they borne wandering on
By blindfold reason. And, Memmius, unless
From out thy mind thou spuest all of this
And casteth far from thee all thoughts which be
Unworthy gods and alien to their peace,
Then often will the holy majesties
Of the high gods be harmful unto thee,
As by thy thought degraded,- not, indeed,
That essence supreme of gods could be by this
So outraged as in wrath to thirst to seek
Revenges keen; but even because thyself
Thou plaguest with the notion that the gods,
Even they, the Calm Ones in serene repose,
Do roll the mighty waves of wrath on wrath;
Nor wilt thou enter with a serene breast
Shrines of the gods; nor wilt thou able be
In tranquil peace of mind to take and know
Those images which from their holy bodies
Are carried into intellects of men,
As the announcers of their form divine.
What sort of life will follow after this
'Tis thine to see. But that afar from us
Veriest reason may drive such life away,
Much yet remains to be embellished yet
In polished verses, albeit hath issued forth
So much from me already; lo, there is
The law and aspect of the sky to be
By reason grasped; there are the tempest times
And the bright lightnings to be hymned now-
Even what they do and from what cause soe'er
They're borne along- that thou mayst tremble not,
Marking off regions of prophetic skies
For auguries, O foolishly distraught
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-
Whereof nowise the causes do men know,
And think divinities are working there.
Do thou, Calliope, ingenious Muse,
Solace of mortals and delight of gods,
Point out the course before me, as I race
On to the white line of the utmost goal,
That I may get with signal praise the crown,
With thee my guide!

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 comes
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 north-west 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 possess
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 inter-mixed 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.
