About these texts #
These are extracts from On the Nature of Things, the poem in which the Roman writer Lucretius set out Epicurean philosophy in the middle of the first century BCE.1 Book III, on death, has a page of its own. The six books together are a long read, so these passages are chosen to show the range: the poem’s mood, its main argument against fear, one of its calmest passages and its best-known physical idea.
The translation is William Ellery Leonard’s unrhymed verse of 1916, now out of copyright.2 The text was taken from the Project Gutenberg transcription, and each passage was checked line by line against that file.34 The curly apostrophes are ours.
Leonard writes in an older register and is sometimes looser than the Latin. His English is longer than the Latin, so the line numbers given here are the Latin ones, and only approximate.5 For a plainer reading, a prose translation is easier to follow alongside.

Hymn to Venus
Lucretius opens a poem on Epicurean philosophy by calling on Venus, the force behind spring, birth and growth, and asks her to calm Mars and bring peace to Rome.6 This surprises many readers, because Epicurus taught that the gods take no part in the affairs of the world.7 Scholars have read the invocation in several ways, from a poetic picture of nature’s creative power to a deliberate gesture towards Roman readers, and the question is still open. The poem is addressed to Memmius, a Roman of rank.
The Greek who stood up to Religion, and Iphigenia
The ‘Greek’ of Book I is Epicurus, who is named in later books.8 The word Leonard translates as ‘Religion’ is the Latin religio, which is often taken to mean something nearer to scrupulous dread of the gods, and the ritual built on it, than to religion in the modern sense. Lucretius does not argue against the gods themselves. He argues against the fear they were thought to cause. The example he gives is the sacrifice of Agamemnon’s daughter at Aulis, and he ends it with a line that is often quoted in Latin: tantum religio potuit suadere malorum, rendered here as ‘Such are the crimes to which Religion leads’.9 The Death and the gods page sets out the Epicurean view of the gods.
The darkness of the mind
These few lines are a refrain. The same words come back at the end of the proem to Book II, and in Book III and Book VI.10 They state the poem’s method: fear of the unknown is cleared by knowing how nature works. You will find that passage twice on this page, once here and once at the end of the passage from Book II.
The view from the high ground
The proem to Book II begins with a famous image of watching a storm at sea from dry land, and Lucretius adds at once that the pleasure is not in other people’s pain but in seeing what we are spared.11 It moves on to how little the body needs. This is the Epicurean teaching that the natural and necessary desires are easily met, which is set out in the Letter to Menoeceus.12 The picture of friends resting on the grass by a river under a big tree is the poem’s plainest image of the good life.
The swerve
Lucretius says that atoms falling through the void must at times turn a little from their path, because without the turn they would fall side by side for ever and nothing would ever collide or be made.13 He then uses the same idea to argue that there is an opening in nature for free action. The swerve is not found in the writings of Epicurus that survive. Our main sources for it are Lucretius and Cicero, who is not a friendly witness.14 Philosophers still argue about what it was meant to do and whether it works; the collection of ancient sources by Long and Sedley gives the evidence side by side.15 The glossary has an entry for the swerve.
The praise of Epicurus
The proem to Book V says that Epicurus deserves to be called a god, because he found the way of life now called philosophy and freed minds from fear and greed, with words and not arms.16 Lucretius ranks that gift above the grain of Ceres, the wine of Bacchus and the labours of Hercules. There is a gap in the text of the transcription, marked with an ellipsis after the three-bodied Geryon. It probably marks a place where the Latin manuscripts are damaged.17 For a plain account of Epicurus, see the Epicurus page.
Read in sequence these passages make a short route through the poem. If one of them draws you in, Book III is the natural next step.

Hymn to Venus
Book I, about 1–43
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.
The Greek who stood up to Religion
Book I, about 62–79
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.
Iphigenia at Aulis
Book I, about 80–101
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.
The darkness of the mind
Book I, about 146–150
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,
Which, teaching us, hath this exordium:
Nothing from nothing ever yet was born.
The view from the high ground
Book II, about 1–61
’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.
The swerve
Book II, about 216–293
In these affairs
We wish thee also well aware of this:
The atoms, as their own weight bears them down
Plumb through the void, at scarce determined times,
In scarce determined places, from their course
Decline a little—call it, so to speak,
Mere changed trend. For were it not their wont
Thuswise to swerve, down would they fall, each one,
Like drops of rain, through the unbottomed void;
And then collisions ne’er could be nor blows
Among the primal elements; and thus
Nature would never have created aught.
But, if perchance be any that believe
The heavier bodies, as more swiftly borne
Plumb down the void, are able from above
To strike the lighter, thus engendering blows
Able to cause those procreant motions, far
From highways of true reason they retire.
For whatsoever through the waters fall,
Or through thin air, must quicken their descent,
Each after its weight—on this account, because
Both bulk of water and the subtle air
By no means can retard each thing alike,
But give more quick before the heavier weight;
But contrariwise the empty void cannot,
On any side, at any time, to aught
Oppose resistance, but will ever yield,
True to its bent of nature. Wherefore all,
With equal speed, though equal not in weight,
Must rush, borne downward through the still inane.
Thus ne’er at all have heavier from above
Been swift to strike the lighter, gendering strokes
Which cause those divers motions, by whose means
Nature transacts her work. And so I say,
The atoms must a little swerve at times—
But only the least, lest we should seem to feign
Motions oblique, and fact refute us there.
For this we see forthwith is manifest:
Whatever the weight, it can’t obliquely go,
Down on its headlong journey from above,
At least so far as thou canst mark; but who
Is there can mark by sense that naught can swerve
At all aside from off its road’s straight line?
Again, if ev’r all motions are co-linked,
And from the old ever arise the new
In fixed order, and primordial seeds
Produce not by their swerving some new start
Of motion to sunder the covenants of fate,
That cause succeed not cause from everlasting,
Whence this free will for creatures o’er the lands,
Whence is it wrested from the fates,—this will
Whereby we step right forward where desire
Leads each man on, whereby the same we swerve
In motions, not as at some fixed time,
Nor at some fixed line of space, but where
The mind itself has urged? For out of doubt
In these affairs ’tis each man’s will itself
That gives the start, and hence throughout our limbs
Incipient motions are diffused. Again,
Dost thou not see, when, at a point of time,
The bars are opened, how the eager strength
Of horses cannot forward break as soon
As pants their mind to do? For it behooves
That all the stock of matter, through the frame,
Be roused, in order that, through every joint,
Aroused, it press and follow mind’s desire;
So thus thou seest initial motion’s gendered
From out the heart, aye, verily, proceeds
First from the spirit’s will, whence at the last
’Tis given forth through joints and body entire.
Quite otherwise it is, when forth we move,
Impelled by a blow of another’s mighty powers
And mighty urge; for then ’tis clear enough
All matter of our total body goes,
Hurried along, against our own desire—
Until the will has pulled upon the reins
And checked it back, throughout our members all;
At whose arbitrament indeed sometimes
The stock of matter’s forced to change its path,
Throughout our members and throughout our joints,
And, after being forward cast, to be
Reined up, whereat it settles back again.
So seest thou not, how, though external force
Drive men before, and often make them move,
Onward against desire, and headlong snatched,
Yet is there something in these breasts of ours
Strong to combat, strong to withstand the same?—
Wherefore no less within the primal seeds
Thou must admit, besides all blows and weight,
Some other cause of motion, whence derives
This power in us inborn, of some free act.—
Since naught from nothing can become, we see.
For weight prevents all things should come to pass
Through blows, as ’twere, by some external force;
But that man’s mind itself in all it does
Hath not a fixed necessity within,
Nor is not, like a conquered thing, compelled
To bear and suffer,—this state comes to man
From that slight swervement of the elements
In no fixed line of space, in no fixed time.
The praise of Epicurus
Book V, about 1–54
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.
