De Rerum Natura

Lucretius

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

An image too may be
From mirror into mirror handed on,
Until of idol-films even five or six
Have thus been gendered. For whatever things
Shall hide back yonder in the house, the same,
However far removed in twisting ways,
May still be all brought forth through bending paths
And by these several mirrors seen to be
Within the house, since nature so compels
All things to be borne backward and spring off
At equal angles from all other things.
To such degree the image gleams across
From mirror unto mirror; where 'twas left
It comes to be the right, and then again
Returns and changes round unto the left.
Again, those little sides of mirrors curved
Proportionate to the bulge of our own flank
Send back to us their idols with the right
Upon the right; and this is so because
Either the image is passed on along
From mirror unto mirror, and thereafter,
When twice dashed off, flies back unto ourselves;
Or else the image wheels itself around,
When once unto the mirror it has come,
Since the curved surface teaches it to turn
To usward. Further, thou might'st well believe
That these film-idols step along with us
And set their feet in unison with ours
And imitate our carriage, since from that
Part of a mirror whence thou hast withdrawn
Straightway no images can be returned.
Further, our eye-balls tend to flee the bright
And shun to gaze thereon; the sun even blinds,
If thou goest on to strain them unto him,
Because his strength is mighty, and the films
Heavily downward from on high are borne
Through the pure ether and the viewless winds,
And strike the eyes, disordering their joints.
So piecing lustre often burns the eyes,
Because it holdeth many seeds of fire
Which, working into eyes, engender pain.
Again, whatever jaundiced people view
Becomes wan-yellow, since from out their bodies
Flow many seeds wan-yellow forth to meet
The films of things, and many too are mixed
Within their eye, which by contagion paint
All things with sallowness.

Again, we view
From dark recesses things that stand in light,
Because, when first has entered and possessed
The open eyes this nearer darkling air,
Swiftly the shining air and luminous
Followeth in, which purges then the eyes
And scatters asunder of that other air
The sable shadows, for in large degrees
This air is nimbler, nicer, and more strong.
And soon as ever 'thas filled and oped with light
The pathways of the eyeballs, which before
Black air had blocked, there follow straightaway
Those films of things out-standing in the light,
Provoking vision- what we cannot do
From out the light with objects in the dark,
Because that denser darkling air behind
Followeth in, and fills each aperture
And thus blockades the pathways of the eyes
That there no images of any things
Can be thrown in and agitate the eyes.
And when from far away we do behold
The squared towers of a city, oft
Rounded they seem,- on this account because
Each distant angle is perceived obtuse,
Or rather it is not perceived at all;
And perishes its blow nor to our gaze
Arrives its stroke, since through such length of air
Are borne along the idols that the air
Makes blunt the idol of the angle's point
By numerous collidings. When thuswise
The angles of the tower each and all
Have quite escaped the sense, the stones appear
As rubbed and rounded on a turner's wheel-
Yet not like objects near and truly round,
But with a semblance to them, shadowily.
Likewise, our shadow in the sun appears
To move along and follow our own steps
And imitate our carriage- if thou thinkest
Air that is thus bereft of light can walk,
Following the gait and motion of mankind.
For what we use to name a shadow, sure
Is naught but air deprived of light. No marvel:
Because the earth from spot to spot is reft
Progressively of light of sun, whenever
In moving round we get within its way,
While any spot of earth by us abandoned
Is filled with light again, on this account
It comes to pass that what was body's shadow
Seems still the same to follow after us
In one straight course. Since, evermore pour in
New lights of rays, and perish then the old,
Just like the wool that's drawn into the flame.
Therefore the earth is easily spoiled of light
And easily refilled and from herself
Washeth the black shadows quite away.

And yet in this we don't at all concede
That eyes be cheated. For their task it is
To note in whatsoever place be light,
In what be shadow: whether or no the gleams
Be still the same, and whether the shadow which
Just now was here is that one passing thither,
Or whether the facts be what we said above,
'Tis after all the reasoning of mind
That must decide; nor can our eyeballs know
The nature of reality. And so
Attach thou not this fault of mind to eyes,
Nor lightly think our senses everywhere
Are tottering. The ship in which we sail
Is borne along, although it seems to stand;
The ship that bides in roadstead is supposed
There to be passing by. And hills and fields
Seem fleeing fast astern, past which we urge
The ship and fly under the bellying sails.
The stars, each one, do seem to pause, affixed
To the ethereal caverns, though they all
Forever are in motion, rising out
And thence revisiting their far descents
When they have measured with their bodies bright
The span of heaven. And likewise sun and moon
Seem biding in a roadstead,- objects which,
As plain fact proves, are really borne along.
Between two mountains far away aloft
From midst the whirl of waters open lies
A gaping exit for the fleet, and yet
They seem conjoined in a single isle.
When boys themselves have stopped their spinning round,
The halls still seem to whirl and posts to reel,
Until they now must almost think the roofs
Threaten to ruin down upon their heads.
And now, when nature begins to lift on high
The sun's red splendour and the tremulous fires,
And raise him o'er the mountain-tops, those mountains-
O'er which he seemeth then to thee to be,
His glowing self hard by atingeing them
With his own fire- are yet away from us
Scarcely two thousand arrow-shots, indeed
Oft scarce five hundred courses of a dart;
Although between those mountains and the sun
Lie the huge plains of ocean spread beneath
The vasty shores of ether, and intervene
A thousand lands, possessed by many a folk
And generations of wild beasts. Again,

A pool of water of but a finger's depth,
Which lies between the stones along the pave,
Offers a vision downward into earth
As far, as from the earth o'erspread on high
The gulfs of heaven; that thus thou seemest to view
Clouds down below and heavenly bodies plunged
Wondrously in heaven under earth.
Then too, when in the middle of the stream
Sticks fast our dashing horse, and down we gaze
Into the river's rapid waves, some force
Seems then to bear the body of the horse,
Though standing still, reversely from his course,
And swiftly push up-stream. And wheresoe'er
We cast our eyes across, all objects seem
Thus to be onward borne and flow along
In the same way as we. A portico,
Albeit it stands well propped from end to end
On equal columns, parallel and big,
Contracts by stages in a narrow cone,
When from one end the long, long whole is seen,-
Until, conjoining ceiling with the floor,
And the whole right side with the left, it draws
Together to a cone's nigh-viewless point.
To sailors on the main the sun he seems
From out the waves to rise, and in the waves
To set and bury his light- because indeed
They gaze on naught but water and the sky.
Again, to gazers ignorant of the sea,
Vessels in port seem, as with broken poops,
To lean upon the water, quite agog;
For any portion of the oars that's raised
Above the briny spray is straight, and straight
The rudders from above. But other parts,
Those sunk, immersed below the water-line,
Seem broken all and bended and inclined
Sloping to upwards, and turned back to float
Almost atop the water. And when the winds
Carry the scattered drifts along the sky
In the night-time, then seem to glide along
The radiant constellations 'gainst the clouds
And there on high to take far other course
From that whereon in truth they're borne. And then,

If haply our hand be set beneath one eye
And press below thereon, then to our gaze
Each object which we gaze on seems to be,
By some sensation twain- then twain the lights
Of lampions burgeoning in flowers of flame,
And twain the furniture in all the house,
Two-fold the visages of fellow-men,
And twain their bodies. And again, when sleep
Has bound our members down in slumber soft
And all the body lies in deep repose,
Yet then we seem to self to be awake
And move our members; and in night's blind gloom
We think to mark the daylight and the sun;
And, shut within a room, yet still we seem
To change our skies, our oceans, rivers, hills,
To cross the plains afoot, and hear new sounds,
Though still the austere silence of the night
Abides around us, and to speak replies,
Though voiceless. Other cases of the sort
Wondrously many do we see, which all
Seek, so to say, to injure faith in sense-
In vain, because the largest part of these
Deceives through mere opinions of the mind,
Which we do add ourselves, feigning to see
What by the senses are not seen at all.
For naught is harder than to separate
Plain facts from dubious, which the mind forthwith
Adds by itself.

Again, if one suppose
That naught is known, he knows not whether this
Itself is able to be known, since he
Confesses naught to know. Therefore with him
I waive discussion- who has set his head
Even where his feet should be. But let me grant
That this he knows,- I question: whence he knows
What 'tis to know and not-to-know in turn,
And what created concept of the truth,
And what device has proved the dubious
To differ from the certain?- since in things
He's heretofore seen naught of true. Thou'lt find
That from the senses first hath been create
Concept of truth, nor can the senses be
Rebutted. For criterion must be found
Worthy of greater trust, which shall defeat
Through own authority the false by true;
What, then, than these our senses must there be
Worthy a greater trust? Shall reason, sprung
From some false sense, prevail to contradict
Those senses, sprung as reason wholly is
From out the senses?- For lest these be true,
All reason also then is falsified.
Or shall the ears have power to blame the eyes,
Or yet the touch the ears? Again, shall taste
Accuse this touch or shall the nose confute
Or eyes defeat it? Methinks not so it is:
For unto each has been divided off
Its function quite apart, its power to each;
And thus we're still constrained to perceive
The soft, the cold, the hot apart, apart
All divers hues and whatso things there be
Conjoined with hues. Likewise the tasting tongue
Has its own power apart, and smells apart
And sounds apart are known. And thus it is
That no one sense can e'er convict another.
Nor shall one sense have power to blame itself,
Because it always must be deemed the same,
Worthy of equal trust. And therefore what
At any time unto these senses showed,
The same is true.

And if the reason be
Unable to unravel us the cause
Why objects, which at hand were square, afar
Seemed rounded, yet it more availeth us,
Lacking the reason, to pretend a cause
For each configuration, than to let
From out our hands escape the obvious things
And injure primal faith in sense, and wreck
All those foundations upon which do rest
Our life and safety. For not only reason
Would topple down; but even our very life
Would straightaway collapse, unless we dared
To trust our senses and to keep away
From headlong heights and places to be shunned
Of a like peril, and to seek with speed
Their opposites! Again, as in a building,
If the first plumb-line be askew, and if
The square deceiving swerve from lines exact,
And if the level waver but the least
In any part, the whole construction then
Must turn out faulty- shelving and askew,
Leaning to back and front, incongruous,
That now some portions seem about to fall,
And falls the whole ere long- betrayed indeed
By first deceiving estimates: so too
Thy calculations in affairs of life
Must be askew and false, if sprung for thee
From senses false. So all that troop of words
Marshalled against the senses is quite vain.

And now remains to demonstrate with ease
How other senses each their things perceive.
Firstly, a sound and every voice is heard,
When, getting into ears, they strike the sense
With their own body. For confess we must
Even voice and sound to be corporeal,
Because they're able on the sense to strike.
Besides voice often scrapes against the throat,
And screams in going out do make more rough
The wind-pipe- naturally enough, methinks,
When, through the narrow exit rising up
In larger throng, these primal germs of voice
Have thus begun to issue forth. In sooth,
Also the door of the mouth is scraped against
[By air blown outward] from distended [cheeks].
. . . . . .
And thus no doubt there is, that voice and words
Consist of elements corporeal,
With power to pain. Nor art thou unaware
Likewise how much of body's ta'en away,
How much from very thews and powers of men
May be withdrawn by steady talk, prolonged
Even from the rising splendour of the morn
To shadows of black evening,- above all
If 't be outpoured with most exceeding shouts.
Therefore the voice must be corporeal,
Since the long talker loses from his frame
A part.
Moreover, roughness in the sound
Comes from the roughness in the primal germs,
As a smooth sound from smooth ones is create;
Nor have these elements a form the same
When the trump rumbles with a hollow roar,
As when barbaric Berecynthian pipe
Buzzes with raucous boomings, or when swans
By night from icy shores of Helicon
With wailing voices raise their liquid dirge.

Thus, when from deep within our frame we force
These voices, and at mouth expel them forth,
The mobile tongue, artificer of words,
Makes them articulate, and too the lips
By their formations share in shaping them.
Hence when the space is short from starting-point
To where that voice arrives, the very words
Must too be plainly heard, distinctly marked.
For then the voice conserves its own formation,
Conserves its shape. But if the space between
Be longer than is fit, the words must be
Through the much air confounded, and the voice
Disordered in its flight across the winds-
And so it haps, that thou canst sound perceive,
Yet not determine what the words may mean;
To such degree confounded and encumbered
The voice approaches us. Again, one word,
Sent from the crier's mouth, may rouse all ears
Among the populace. And thus one voice
Scatters asunder into many voices,
Since it divides itself for separate ears,
Imprinting form of word and a clear tone.
But whatso part of voices fails to hit
The ears themselves perishes, borne beyond,
Idly diffused among the winds. A part,
Beating on solid porticoes, tossed back
Returns a sound; and sometimes mocks the ear
With a mere phantom of a word.

When this
Thou well hast noted, thou canst render count
Unto thyself and others why it is
Along the lonely places that the rocks
Give back like shapes of words in order like,
When search we after comrades wandering
Among the shady mountains, and aloud
Call unto them, the scattered. I have seen
Spots that gave back even voices six or seven
For one thrown forth- for so the very hills,
Dashing them back against the hills, kept on
With their reverberations. And these spots
The neighbouring country-side doth feign to be
Haunts of the goat-foot satyrs and the nymphs;
And tells ye there be fauns, by whose night noise
And antic revels yonder they declare
The voiceless silences are broken oft,
And tones of strings are made and wailings sweet
Which the pipe, beat by players' finger-tips,
Pours out; and far and wide the farmer-race
Begins to hear, when, shaking the garmentings
Of pine upon his half-beast head, god-Pan
With puckered lip oft runneth o'er and o'er
The open reeds,- lest flute should cease to pour
The woodland music! Other prodigies
And wonders of this ilk they love to tell,
Lest they be thought to dwell in lonely spots
And even by gods deserted. This is why
They boast of marvels in their story-tellings;
Or by some other reason are led on-
Greedy, as all mankind hath ever been,
To prattle fables into ears.

Again,
One need not wonder how it comes about
That through those places (through which eyes cannot
View objects manifest) sounds yet may pass
And assail the ears. For often we observe
People conversing, though the doors be closed;
No marvel either, since all voice unharmed
Can wind through bended apertures of things,
While idol-films decline to- for they're rent,
Unless along straight apertures they swim,
Like those in glass, through which all images
Do fly across. And yet this voice itself,
In passing through shut chambers of a house,
Is dulled, and in a jumble enters ears,
And sound we seem to hear far more than words.
Moreover, a voice is into all directions
Divided up, since off from one another
New voices are engendered, when one voice
Hath once leapt forth, outstarting into many-
As oft a spark of fire is wont to sprinkle
Itself into its several fires. And so,
Voices do fill those places hid behind,
Which all are in a hubbub round about,
Astir with sound. But idol-films do tend,
As once sent forth, in straight directions all;
Wherefore one can inside a wall see naught,
Yet catch the voices from beyond the same.

Nor tongue and palate, whereby we flavour feel,
Present more problems for more work of thought.
Firstly, we feel a flavour in the mouth,
When forth we squeeze it, in chewing up our food,-
As any one perchance begins to squeeze
With hand and dry a sponge with water soaked.
Next, all which forth we squeeze is spread about
Along the pores and intertwined paths
Of the loose-textured tongue. And so, when smooth
The bodies of the oozy flavour, then
Delightfully they touch, delightfully
They treat all spots, around the wet and trickling
Enclosures of the tongue. And contrariwise,
They sting and pain the sense with their assault,
According as with roughness they're supplied.
Next, only up to palate is the pleasure
Coming from flavour; for in truth when down
'Thas plunged along the throat, no pleasure is,
Whilst into all the frame it spreads around;
Nor aught it matters with what food is fed
The body, if only what thou take thou canst
Distribute well digested to the frame
And keep the stomach in a moist career.
Now, how it is we see some food for some,
Others for others....
. . . . . .
I will unfold, or wherefore what to some
Is foul and bitter, yet the same to others
Can seem delectable to eat,- why here
So great the distance and the difference is
That what is food to one to some becomes
Fierce poison, as a certain snake there is
Which, touched by spittle of a man, will waste
And end itself by gnawing up its coil.
Again, fierce poison is the hellebore
To us, but puts the fat on goats and quails.
That thou mayst know by what devices this
Is brought about, in chief thou must recall
What we have said before, that seeds are kept
Commixed in things in divers modes. Again,
As all the breathing creatures which take food
Are outwardly unlike, and outer cut
And contour of their members bounds them round,
Each differing kind by kind, they thus consist
Of seeds of varying shape. And furthermore,
Since seeds do differ, divers too must be
The interstices and paths (which we do call
The apertures) in all the members, even
In mouth and palate too. Thus some must be
More small or yet more large, three-cornered some
And others squared, and many others round,
And certain of them many-angled too
In many modes. For, as the combination
And motion of their divers shapes demand,
The shapes of apertures must be diverse
And paths must vary according to their walls
That bound them. Hence when what is sweet to some,
Becomes to others bitter, for him to whom
'Tis sweet, the smoothest particles must needs
Have entered caressingly the palate's pores.
And, contrariwise, with those to whom that sweet
Is sour within the mouth, beyond a doubt
The rough and barbed particles have got
Into the narrows of the apertures.
Now easy it is from these affairs to know
Whatever...
. . . . . .
Indeed, where one from o'er-abundant bile
Is stricken with fever, or in other wise
Feels the roused violence of some malady,
There the whole frame is now upset, and there
All the positions of the seeds are changed,-
So that the bodies which before were fit
To cause the savour, now are fit no more,
And now more apt are others which be able
To get within the pores and gender sour.
Both sorts, in sooth, are intermixed in honey-
What oft we've proved above to thee before.

Now come, and I will indicate what wise
Impact of odour on the nostrils touches.
And first, 'tis needful there be many things
From whence the streaming flow of varied odours
May roll along, and we're constrained to think
They stream and dart and sprinkle themselves about
Impartially. But for some breathing creatures
One odour is more apt, to others another-
Because of differing forms of seeds and pores.
Thus on and on along the zephyrs bees
Are led by odour of honey, vultures too
By carcasses. Again, the forward power
Of scent in dogs doth lead the hunter on
Whithersoever the splay-foot of wild beast
Hath hastened its career; and the white goose,
The saviour of the Roman citadel,
Forescents afar the odour of mankind.
Thus, diversly to divers ones is given
Peculiar smell that leadeth each along
To his own food or makes him start aback
From loathsome poison, and in this wise are
The generations of the wild preserved.
Yet is this pungence not alone in odours
Or in the class of flavours; but, likewise,
The look of things and hues agree not all
So well with senses unto all, but that
Some unto some will be, to gaze upon,
More keen and painful. Lo, the raving lions,
They dare not face and gaze upon the cock
Who's wont with wings to flap away the night
From off the stage, and call the beaming morn
With clarion voice- and lions straightway thus
Bethink themselves of flight, because, ye see,
Within the body of the cocks there be
Some certain seeds, which, into lions' eyes
Injected, bore into the pupils deep
And yield such piercing pain they can't hold out
Against the cocks, however fierce they be-
Whilst yet these seeds can't hurt our gaze the least,
Either because they do not penetrate,
Or since they have free exit from the eyes
As soon as penetrating, so that thus
They cannot hurt our eyes in any part
By there remaining.
To speak once more of odour;
Whatever assail the nostrils, some can travel
A longer way than others. None of them,
However, 's borne so far as sound or voice-
While I omit all mention of such things
As hit the eyesight and assail the vision.
For slowly on a wandering course it comes
And perishes sooner, by degrees absorbed
Easily into all the winds of air;-
And first, because from deep inside the thing
It is discharged with labour (for the fact
That every object, when 'tis shivered, ground,
Or crumbled by the fire, will smell the stronger
Is sign that odours flow and part away
From inner regions of the things). And next,
Thou mayest see that odour is create
Of larger primal germs than voice, because
It enters not through stony walls, wherethrough
Unfailingly the voice and sound are borne;
Wherefore, besides, thou wilt observe 'tis not
So easy to trace out in whatso place
The smelling object is. For, dallying on
Along the winds, the particles cool off,
And then the scurrying messengers of things
Arrive our senses, when no longer hot.
So dogs oft wander astray, and hunt the scent.

Now mark, and hear what objects move the mind,
And learn, in few, whence unto intellect
Do come what come. And first I tell thee this:
That many images of objects rove
In many modes to every region round-
So thin that easily the one with other,
When once they meet, uniteth in mid-air,
Like gossamer or gold-leaf. For, indeed,
Far thinner are they in their fabric than
Those images which take a hold on eyes
And smite the vision, since through body's pores
They penetrate, and inwardly stir up
The subtle nature of mind and smite the sense.
Thus, Centaurs and the limbs of Scyllas, thus
The Cerberus-visages of dogs we see,
And images of people gone before-
Dead men whose bones earth bosomed long ago;
Because the images of every kind
Are everywhere about us borne- in part
Those which are gendered in the very air
Of own accord, in part those others which
From divers things do part away, and those
Which are compounded, made from out their shapes.
For soothly from no living Centaur is
That phantom gendered, since no breed of beast
Like him was ever; but, when images
Of horse and man by chance have come together,
They easily cohere, as aforesaid,
At once, through subtle nature and fabric thin.
In the same fashion others of this ilk
Created are. And when they're quickly borne
In their exceeding lightness, easily
(As earlier I showed) one subtle image,
Compounded, moves by its one blow the mind,
Itself so subtle and so strangely quick.
That these things come to pass as I record,
From this thou easily canst understand:
So far as one is unto other like,
Seeing with mind as well as with the eyes
Must come to pass in fashion not unlike.
Well, now, since I have shown that I perceive
Haply a lion through those idol-films
Such as assail my eyes, 'tis thine to know
Also the mind is in like manner moved,
And sees, nor more nor less than eyes do see
(Except that it perceives more subtle films)
The lion and aught else through idol-films.
And when the sleep has overset our frame,
The mind's intelligence is now awake,
Still for no other reason, save that these-
The self-same films as when we are awake-
Assail our minds, to such degree indeed
That we do seem to see for sure the man
Whom, void of life, now death and earth have gained
Dominion over. And nature forces this
To come to pass because the body's senses
Are resting, thwarted through the members all,
Unable now to conquer false with true;
And memory lies prone and languishes
In slumber, nor protests that he, the man
Whom the mind feigns to see alive, long since
Hath been the gain of death and dissolution.
And further, 'tis no marvel idols move
And toss their arms and other members round
In rhythmic time- and often in men's sleeps
It haps an image this is seen to do;
In sooth, when perishes the former image,
And other is gendered of another pose,
That former seemeth to have changed its gestures.
Of course the change must be conceived as speedy;
So great the swiftness and so great the store
Of idol-things, and (in an instant brief
As mind can mark) so great, again, the store
Of separate idol-parts to bring supplies.
It happens also that there is supplied
Sometimes an image not of kind the same;
But what before was woman, now at hand
Is seen to stand there, altered into male;
Or other visage, other age succeeds;
But slumber and oblivion take care
That we shall feel no wonder at the thing.

And much in these affairs demands inquiry,
And much, illumination- if we crave
With plainness to exhibit facts. And first,
Why doth the mind of one to whom the whim
To think has come behold forthwith that thing?
Or do the idols watch upon our will,
And doth an image unto us occur,
Directly we desire- if heart prefer
The sea, the land, or after all the sky?
Assemblies of the citizens, parades,
Banquets, and battles, these and all doth she,
Nature, create and furnish at our word?-
Maugre the fact that in same place and spot
Another's mind is meditating things
All far unlike. And what, again, of this:
When we in sleep behold the idols step,
In measure, forward, moving supple limbs,
Whilst forth they put each supple arm in turn
With speedy motion, and with eyeing heads
Repeat the movement, as the foot keeps time?
Forsooth, the idols they are steeped in art,
And wander to and fro well taught indeed,-
Thus to be able in the time of night
To make such games! Or will the truth be this:
Because in one least moment that we mark-
That is, the uttering of a single sound-
There lurk yet many moments, which the reason
Discovers to exist, therefore it comes
That, in a moment how so brief ye will,
The divers idols are hard by, and ready
Each in its place diverse? So great the swiftness,
So great, again, the store of idol-things,
And so, when perishes the former image,
And other is gendered of another pose,
The former seemeth to have changed its gestures.
And since they be so tenuous, mind can mark
Sharply alone the ones it strains to see;
And thus the rest do perish one and all,
Save those for which the mind prepares itself.
Further, it doth prepare itself indeed,
And hopes to see what follows after each-
Hence this result. For hast thou not observed
How eyes, essaying to perceive the fine,
Will strain in preparation, otherwise
Unable sharply to perceive at all?
Yet know thou canst that, even in objects plain,
If thou attendest not, 'tis just the same
As if 'twere all the time removed and far.
What marvel, then, that mind doth lose the rest,
Save those to which 'thas given up itself?
So 'tis that we conjecture from small signs
Things wide and weighty, and involve ourselves
In snarls of self-deceit.

In these affairs
We crave that thou wilt passionately flee
The one offence, and anxiously wilt shun
The error of presuming the clear lights
Of eyes created were that we might see;
Or thighs and knees, aprop upon the feet,
Thuswise can bended be, that we might step
With goodly strides ahead; or forearms joined
Unto the sturdy uppers, or serving hands
On either side were given, that we might do
Life's own demands. All such interpretation
Is aft-for-fore with inverse reasoning,
Since naught is born in body so that we
May use the same, but birth engenders use:
No seeing ere the lights of eyes were born,
No speaking ere the tongue created was;
But origin of tongue came long before
Discourse of words, and ears created were
Much earlier than any sound was heard;
And all the members, so meseems, were there
Before they got their use: and therefore, they
Could not be gendered for the sake of use.
But contrariwise, contending in the fight
With hand to hand, and rending of the joints,
And fouling of the limbs with gore, was there,
O long before the gleaming spears ere flew;
And nature prompted man to shun a wound,
Before the left arm by the aid of art
Opposed the shielding targe. And, verily,
Yielding the weary body to repose,
Far ancienter than cushions of soft beds,
And quenching thirst is earlier than cups.
These objects, therefore, which for use and life
Have been devised, can be conceived as found
For sake of using. But apart from such
Are all which first were born and afterwards
Gave knowledge of their own utility-
Chief in which sort we note the senses, limbs:
Wherefore, again, 'tis quite beyond thy power
To hold that these could thus have been create
For office of utility.

Likewise,
'Tis nothing strange that all the breathing creatures
Seek, even by nature of their frame, their food.
Yes, since I've taught thee that from off the things
Stream and depart innumerable bodies
In modes innumerable too; but most
Must be the bodies streaming from the living-
Which bodies, vexed by motion evermore,
Are through the mouth exhaled innumerable,
When weary creatures pant, or through the sweat
Squeezed forth innumerable from deep within.
Thus body rarefies, so undermined
In all its nature, and pain attends its state.
And so the food is taken to underprop
The tottering joints, and by its interfusion
To re-create their powers, and there stop up
The longing, open-mouthed through limbs and veins,
For eating. And the moist no less departs
Into all regions that demand the moist;
And many heaped-up particles of hot,
Which cause such burnings in these bellies of ours,
The liquid on arriving dissipates
And quenches like a fire, that parching heat
No longer now can scorch the frame. And so,
Thou seest how panting thirst is washed away
From off our body, how the hunger-pang
It, too, appeased.

Now, how it comes that we,
Whene'er we wish, can step with strides ahead,
And how 'tis given to move our limbs about,
And what device is wont to push ahead
This the big load of our corporeal frame,
I'll say to thee- do thou attend what's said.
I say that first some idol-films of walking
Into our mind do fall and smite the mind,
As said before. Thereafter will arises;
For no one starts to do a thing, before
The intellect previsions what it wills;
And what it there pre-visioneth depends
On what that image is. When, therefore, mind
Doth so bestir itself that it doth will
To go and step along, it strikes at once
That energy of soul that's sown about
In all the body through the limbs and frame-
And this is easy of performance, since
The soul is close conjoined with the mind.
Next, soul in turn strikes body, and by degrees
Thus the whole mass is pushed along and moved.
Then too the body rarefies, and air,
Forsooth as ever of such nimbleness,
Comes on and penetrates aboundingly
Through opened pores, and thus is sprinkled round
Unto all smallest places in our frame.
Thus then by these twain factors, severally,
Body is borne like ship with oars and wind.
Nor yet in these affairs is aught for wonder
That particles so fine can whirl around
So great a body and turn this weight of ours;
For wind, so tenuous with its subtle body,
Yet pushes, driving on the mighty ship
Of mighty bulk; one hand directs the same,
Whatever its momentum, and one helm
Whirls it around, whither ye please; and loads,
Many and huge, are moved and hoisted high
By enginery of pulley-blocks and wheels,
With but light strain.

Now, by what modes this sleep
Pours through our members waters of repose
And frees the breast from cares of mind, I'll tell
In verses sweeter than they many are;
Even as the swan's slight note is better far
Than that dispersed clamour of the cranes
Among the southwind's aery clouds. Do thou
Give me sharp ears and a sagacious mind,-
That thou mayst not deny the things to be
Whereof I'm speaking, nor depart away
With bosom scorning these the spoken truths,
Thyself at fault unable to perceive.
Sleep chiefly comes when energy of soul
Hath now been scattered through the frame, and part
Expelled abroad and gone away, and part
Crammed back and settling deep within the frame-
Whereafter then our loosened members droop.
For doubt is none that by the work of soul
Exist in us this sense, and when by slumber
That sense is thwarted, we are bound to think
The soul confounded and expelled abroad-
Yet not entirely, else the frame would lie
Drenched in the everlasting cold of death.
In sooth, where no one part of soul remained
Lurking among the members, even as fire
Lurks buried under many ashes, whence
Could sense amain rekindled be in members,
As flame can rise anew from unseen fire?

By what devices this strange state and new
May be occasioned, and by what the soul
Can be confounded and the frame grow faint,
I will untangle: see to it, thou, that I
Pour forth my words not unto empty winds.
In first place, body on its outer parts-
Since these are touched by neighbouring aery gusts-
Must there be thumped and strook by blows of air
Repeatedly. And therefore almost all
Are covered either with hides, or else with shells,
Or with the horny callus, or with bark.
Yet this same air lashes their inner parts,
When creatures draw a breath or blow it out.
Wherefore, since body thus is flogged alike
Upon the inside and the out, and blows
Come in upon us through the little pores
Even inward to our body's primal parts
And primal elements, there comes to pass
By slow degrees, along our members then,
A kind of overthrow; for then confounded
Are those arrangements of the primal germs
Of body and of mind. It comes to pass
That next a part of soul's expelled abroad,
A part retreateth in recesses hid,
A part, too, scattered all about the frame,
Cannot become united nor engage
In interchange of motion. Nature now
So hedges off approaches and the paths;
And thus the sense, its motions all deranged,
Retires down deep within; and since there's naught,
As 'twere, to prop the frame, the body weakens,
And all the members languish, and the arms
And eyelids fall, and, as ye lie abed,
Even there the houghs will sag and loose their powers.
Again, sleep follows after food, because
The food produces same result as air,
Whilst being scattered round through all the veins;
And much the heaviest is that slumber which,
Full or fatigued, thou takest; since 'tis then
That the most bodies disarrange themselves,
Bruised by labours hard. And in same wise,
This three-fold change: a forcing of the soul
Down deeper, more a casting-forth of it,
A moving more divided in its parts
And scattered more.
