On the Nature of Things

BOOK I

Mother of Rome, delight of Gods and men,
Dear Venus that beneath the gliding stars
Makest to teem the many-voyaged main
And fruitful lands— for all of living things
Through thee alone are evermore conceived,
Through thee are risen to visit the great sun—
Before thee, Goddess, and thy coming on,
Flee stormy wind and massy cloud away,
For thee the daedal Earth bears scented flowers,
For thee waters of the unvexed deep
Smile, and the hollows of the serene sky
Glow with diffused radiance for thee!
For soon as comes the springtime face of day,
And procreant gales blow from the West unbarred,
First fowls of air, smit to the heart by thee,
Foretoken thy approach, O thou Divine,
And leap the wild herds round the happy fields
Or swim the bounding torrents. Thus amain,
Seized with the spell, all creatures follow thee
Whithersoever thou walkest forth to lead,
And thence through seas and mountains and swift streams,
Through leafy homes of birds and greening plains,
Kindling the lure of love in every breast,
Thou bringest the eternal generations forth,
Kind after kind. And since ’tis thou alone
Guidest the Cosmos, and without thee naught
Is risen to reach the shining shores of light,
Nor aught of joyful or of lovely born,
Thee do I crave co-partner in that verse
Which I presume on Nature to compose
For Memmius mine, whom thou hast willed to be
Peerless in every grace at every hour—
Wherefore indeed, Divine one, give my words
Immortal charm. Lull to a timely rest
O’er sea and land the savage works of war,
For thou alone hast power with public peace
To aid mortality; since he who rules
The savage works of battle, puissant Mars,
How often to thy bosom flings his strength
O’ermastered by the eternal wound of love—
And there, with eyes and full throat backward thrown,
Gazing, my Goddess, open-mouthed at thee,
Pastures on love his greedy sight, his breath
Hanging upon thy lips. Him thus reclined
Fill with thy holy body, round, above!
Pour from those lips soft syllables to win
Peace for the Romans, glorious Lady, peace!
For in a season troublous to the state
Neither may I attend this task of mine
With thought untroubled, nor mid such events
The illustrious scion of the Memmian house
Neglect the civic cause.
Whilst human kind
Throughout the lands lay miserably crushed
Before all eyes beneath Religion— who
Would show her head along the region skies,
Glowering on mortals with her hideous face—
A Greek it was who first opposing dared
Raise mortal eyes that terror to withstand,
Whom nor the fame of Gods nor lightning’s stroke
Nor threatening thunder of the ominous sky
Abashed; but rather chafed to angry zest
His dauntless heart to be the first to rend
The crossbars at the gates of Nature old.
And thus his will and hardy wisdom won;
And forward thus he fared afar, beyond
The flaming ramparts of the world, until
He wandered the unmeasurable All.
Whence he to us, a conqueror, reports
What things can rise to being, what cannot,
And by what law to each its scope prescribed,
Its boundary stone that clings so deep in Time.
Wherefore Religion now is under foot,
And us his victory now exalts to heaven.
I know how hard it is in Latian verse
To tell the dark discoveries of the Greeks,
Chiefly because our pauper-speech must find
Strange terms to fit the strangeness of the thing;
Yet worth of thine and the expected joy
Of thy sweet friendship do persuade me on
To bear all toil and wake the clear nights through,
Seeking with what of words and what of song
I may at last most gloriously uncloud
For thee the light beyond, wherewith to view
The core of being at the centre hid.
And for the rest, summon to judgments true,
Unbusied ears and singleness of mind
Withdrawn from cares; lest these my gifts, arranged
For thee with eager service, thou disdain
Before thou comprehendest: since for thee
I prove the supreme law of Gods and sky,
And the primordial germs of things unfold,
Whence Nature all creates, and multiplies
And fosters all, and whither she resolves
Each in the end when each is overthrown.
This ultimate stock we have devised to name
Procreant atoms, matter, seeds of things,
Or primal bodies, as primal to the world.
I fear perhaps thou deemest that we fare
An impious road to realms of thought profane;
But ’tis that same religion oftener far
Hath bred the foul impieties of men:
As once at Aulis, the elected chiefs,
Foremost of heroes, Danaan counsellors,
Defiled Diana’s altar, virgin queen,
With Agamemnon’s daughter, foully slain.
She felt the chaplet round her maiden locks
And fillets, fluttering down on either cheek,
And at the altar marked her grieving sire,
The priests beside him who concealed the knife,
And all the folk in tears at sight of her.
With a dumb terror and a sinking knee
She dropped; nor might avail her now that first
’Twas she who gave the king a father’s name.
They raised her up, they bore the trembling girl
On to the altar— hither led not now
With solemn rites and hymeneal choir,
But sinless woman, sinfully foredone,
A parent felled her on her bridal day,
Making his child a sacrificial beast
To give the ships auspicious winds for Troy:
Such are the crimes to which Religion leads.
And there shall come the time when even thou,
Forced by the soothsayer’s terror-tales, shalt seek
To break from us. Ah, many a dream even now
Can they concoct to rout thy plans of life,
And trouble all thy fortunes with base fears.
I own with reason: for, if men but knew
Some fixed end to ills, they would be strong
By some device unconquered to withstand
Religions and the menacings of seers.
But now nor skill nor instrument is theirs,
Since men must dread eternal pains in death.
For what the soul may be they do not know,
Whether ’tis born, or enter in at birth,
And whether, snatched by death, it die with us,
Or visit the shadows and the vasty caves
Of Orcus, or by some divine decree
Enter the brute herds, as our Ennius sang,
Who first from lovely Helicon brought down
A laurel wreath of bright perennial leaves,
Renowned forever among the Italian clans.
Yet Ennius too in everlasting verse
Proclaims those vaults of Acheron to be,
Though thence, he said, nor souls nor bodies fare,
But only phantom figures, strangely wan,
And tells how once from out those regions rose
Old Homer’s ghost to him and shed salt tears
And with his words unfolded Nature’s source.
Then be it ours with steady mind to clasp
The purport of the skies— the law behind
The wandering courses of the sun and moon;
To scan the powers that speed all life below;
But most to see with reasonable eyes
Of what the mind, of what the soul is made,
And what it is so terrible that breaks
On us asleep, or waking in disease,
Until we seem to mark and hear at hand
Dead men whose bones earth bosomed long ago.

BOOK II

’Tis sweet, when, down the mighty main, the winds
Roll up its waste of waters, from the land
To watch another’s labouring anguish far,
Not that we joyously delight that man
Should thus be smitten, but because ’tis sweet
To mark what evils we ourselves be spared;
’Tis sweet, again, to view the mighty strife
Of armies embattled yonder o’er the plains,
Ourselves no sharers in the peril; but naught
There is more goodly than to hold the high
Serene plateaus, well fortressed by the wise,
Whence thou may’st look below on other men
And see them ev’rywhere wand’ring, all dispersed
In their lone seeking for the road of life;
Rivals in genius, or emulous in rank,
Pressing through days and nights with hugest toil
For summits of power and mastery of the world.
O wretched minds of men! O blinded hearts!
In how great perils, in what darks of life
Are spent the human years, however brief!—
O not to see that nature for herself
Barks after nothing, save that pain keep off,
Disjoined from the body, and that mind enjoy
Delightsome feeling, far from care and fear!
Therefore we see that our corporeal life
Needs little, altogether, and only such
As takes the pain away, and can besides
Strew underneath some number of delights.
More grateful ’tis at times (for nature craves
No artifice nor luxury), if forsooth
There be no golden images of boys
Along the halls, with right hands holding out
The lamps ablaze, the lights for evening feasts,
And if the house doth glitter not with gold
Nor gleam with silver, and to the lyre resound
No fretted and gilded ceilings overhead,
Yet still to lounge with friends in the soft grass
Beside a river of water, underneath
A big tree’s boughs, and merrily to refresh
Our frames, with no vast outlay— most of all
If the weather is laughing and the times of the year
Besprinkle the green of the grass around with flowers.
Nor yet the quicker will hot fevers go,
If on a pictured tapestry thou toss,
Or purple robe, than if ’tis thine to lie
Upon the poor man’s bedding. Wherefore, since
Treasure, nor rank, nor glory of a reign
Avail us naught for this our body, thus
Reckon them likewise nothing for the mind:
Save then perchance, when thou beholdest forth
Thy legions swarming round the Field of Mars,
Rousing a mimic warfare— either side
Strengthened with large auxiliaries and horse,
Alike equipped with arms, alike inspired;
Or save when also thou beholdest forth
Thy fleets to swarm, deploying down the sea:
For then, by such bright circumstance abashed,
Religion pales and flees thy mind; O then
The fears of death leave heart so free of care.
But if we note how all this pomp at last
Is but a drollery and a mocking sport,
And of a truth man’s dread, with cares at heels,
Dreads not these sounds of arms, these savage swords
But among kings and lords of all the world
Mingles undaunted, nor is overawed
By gleam of gold nor by the splendour bright
Of purple robe, canst thou then doubt that this
Is aught, but power of thinking?— when, besides
The whole of life but labours in the dark.
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.

BOOK III

O thou who first uplifted in such dark
So clear a torch aloft, who first shed light
Upon the profitable ends of man,
O thee I follow, glory of the Greeks,
And set my footsteps squarely planted now
Even in the impress and the marks of thine—
Less like one eager to dispute the palm,
More as one craving out of very love
That I may copy thee!— for how should swallow
Contend with swans or what compare could be
In a race between young kids with tumbling legs
And the strong might of the horse? Our father thou,
And finder-out of truth, and thou to us
Suppliest a father’s precepts; and from out
Those scriven leaves of thine, renowned soul
(Like bees that sip of all in flowery wolds),
We feed upon thy golden sayings all—
Golden, and ever worthiest endless life.
For soon as ever thy planning thought that sprang
From god-like mind begins its loud proclaim
Of nature’s courses, terrors of the brain
Asunder flee, the ramparts of the world
Dispart away, and through the void entire
I see the movements of the universe.
Rises to vision the majesty of gods,
And their abodes of everlasting calm
Which neither wind may shake nor rain-cloud splash,
Nor snow, congealed by sharp frosts, may harm
With its white downfall: ever, unclouded sky
O’er roofs, and laughs with far-diffused light.
And nature gives to them their all, nor aught
May ever pluck their peace of mind away.
But nowhere to my vision rise no more
The vaults of Acheron, though the broad earth
Bars me no more from gazing down o’er all
Which under our feet is going on below
Along the void. O, here in these affairs
Some new divine delight and trembling awe
Takes hold through me, that thus by power of thine
Nature, so plain and manifest at last,
Hath been on every side laid bare to man!
And since I’ve taught already of what sort
The seeds of all things are, and how, distinct
In divers forms, they flit of own accord,
Stirred with a motion everlasting on,
And in what mode things be from them create,
Now, after such matters, should my verse, meseems,
Make clear the nature of the mind and soul,
And drive that dread of Acheron without,
Headlong, which so confounds our human life
Unto its deeps, pouring o’er all that is
The black of death, nor leaves not anything
To prosper— a liquid and unsullied joy.
For as to what men sometimes will affirm:
That more than Tartarus (the realm of death)
They fear diseases and a life of shame,
And know the substance of the soul is blood,
Or rather wind (if haply thus their whim),
And so need naught of this our science, then
Thou well may’st note from what’s to follow now
That more for glory do they braggart forth
Than for belief. For mark these very same:
Exiles from country, fugitives afar
From sight of men, with charges foul attaint,
Abased with every wretchedness, they yet
Live, and where’er the wretches come, they yet
Make the ancestral sacrifices there,
Butcher the black sheep, and to gods below
Offer the honours, and in bitter case
Turn much more keenly to religion.
Wherefore, it’s surer testing of a man
In doubtful perils— mark him as he is
Amid adversities; for then alone
Are the true voices conjured from his breast,
The mask off-stripped, reality behind.
And greed, again, and the blind lust of honours
Which force poor wretches past the bounds of law,
And, oft allies and ministers of crime,
To push through nights and days with hugest toil
To rise untrammelled to the peaks of power—
These wounds of life in no mean part are kept
Festering and open by this fright of death.
For ever we see fierce Want and foul Disgrace
Dislodged afar from secure life and sweet,
Like huddling Shapes before the doors of death.
And whilst, from these, men wish to scape afar,
Driven by false terror, and afar remove,
With civic blood a fortune they amass,
They double their riches, greedy, heapers-up
Of corpse on corpse they have a cruel laugh
For the sad burial of a brother-born,
And hatred and fear of tables of their kin.
Likewise, through this same terror, envy oft
Makes them to peak because before their eyes
That man is lordly, that man gazed upon
Who walks begirt with honour glorious,
Whilst they in filth and darkness roll around;
Some perish away for statues and a name,
And oft to that degree, from fright of death,
Will hate of living and beholding light
Take hold on humankind that they inflict
Their own destruction with a gloomy heart—
Forgetful that this fear is font of cares,
This fear the plague upon their sense of shame,
And this that breaks the ties of comradry
And oversets all reverence and faith,
Mid direst slaughter. For long ere to-day
Often were traitors to country and dear parents
Through quest to shun the realms of Acheron.
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 sun disperse,
But only nature’s aspect and her law.

BOOK IV

I wander afield, thriving in sturdy thought,
Through unpathed haunts of the Pierides,
Trodden by step of none before. I joy
To come on undefiled fountains there,
To drain them deep; I joy to pluck new flowers,
To seek for this my head a signal crown
From regions where the Muses never yet
Have garlanded the temples of a man:
First, since I teach concerning mighty things,
And go right on to loose from round the mind
The tightened coils of dread religion;
Next, since, concerning themes so dark, I frame
Song so pellucid, touching all throughout
Even with the Muses’ charm— which, as ‘twould seem,
Is not without a reasonable ground:
For as physicians, when they seek to give
Young boys the nauseous wormwood, first do touch
The brim around the cup with the sweet juice
And yellow of the honey, in order that
The thoughtless age of boyhood be cajoled
As far as the lips, and meanwhile swallow down
The wormwood’s bitter draught, and, though befooled,
Be yet not merely duped, but rather thus
Grow strong again with recreated health:
So now I too (since this my doctrine seems
In general somewhat woeful unto those
Who’ve had it not in hand, and since the crowd
Starts back from it in horror) have desired
To expound our doctrine unto thee in song
Soft-speaking and Pierian, and, as ’twere,
To touch it with sweet honey of the Muse—
If by such method haply I might hold
The mind of thee upon these lines of ours,
Till thou dost learn the nature of all things
And understandest their utility.

BOOK V

O WHO can build with puissant breast a song
Worthy the majesty of these great finds?
Or who in words so strong that he can frame
The fit laudations for deserts of him
Who left us heritors of such vast prizes,
By his own breast discovered and sought out?—
There shall be none, methinks, of mortal stock.
For if must needs be named for him the name
Demanded by the now known majesty
Of these high matters, then a god was he,—
Hear me, illustrious Memmius— a god;
Who first and chief found out that plan of life
Which now is called philosophy, and who
By cunning craft, out of such mighty waves,
Out of such mighty darkness, moored life
In havens so serene, in light so clear.
Compare those old discoveries divine
Of others: lo, according to the tale,
Ceres established for mortality
The grain, and Bacchus juice of vine-born grape,
Though life might yet without these things abide,
Even as report saith now some peoples live.
But man’s well-being was impossible
Without a breast all free. Wherefore the more
That man doth justly seem to us a god,
From whom sweet solaces of life, afar
Distributed o’er populous domains,
Now soothe the minds of men. But if thou thinkest
Labours of Hercules excel the same,
Much farther from true reasoning thou farest.
For what could hurt us now that mighty maw
Of Nemeaean Lion, or what the Boar
Who bristled in Arcadia? Or, again,
O what could Cretan Bull, or Hydra, pest
Of Lerna, fenced with vipers venomous?
Or what the triple-breasted power of her
The three-fold Geryon...
The sojourners in the Stymphalian fens
So dreadfully offend us, or the Steeds
Of Thracian Diomedes breathing fire
From out their nostrils off along the zones
Bistonian and Ismarian? And the Snake,
The dread fierce gazer, guardian of the golden
And gleaming apples of the Hesperides,
Coiled round the tree-trunk with tremendous bulk,
O what, again, could he inflict on us
Along the Atlantic shore and wastes of sea?—
Where neither one of us approacheth nigh
Nor no barbarian ventures. And the rest
Of all those monsters slain, even if alive,
Unconquered still, what injury could they do?
None, as I guess. For so the glutted earth
Swarms even now with savage beasts, even now
Is filled with anxious terrors through the woods
And mighty mountains and the forest deeps—
Quarters ’tis ours in general to avoid.
But lest the breast be purged, what conflicts then,
What perils, must bosom, in our own despite!
O then how great and keen the cares of lust
That split the man distraught! How great the fears!
And lo, the pride, grim greed, and wantonness—
How great the slaughters in their train! and lo,
Debaucheries and every breed of sloth!
Therefore that man who subjugated these,
And from the mind expelled, by words indeed,
Not arms, O shall it not be seemly him
To dignify by ranking with the gods?—
And all the more since he was wont to give,
Concerning the immortal gods themselves,
Many pronouncements with a tongue divine,
And to unfold by his pronouncements all
The nature of the world.

BOOK VI

’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!
