Bodies that strike the eyes, awaking sight. 
From certain things flow odours evermore, 
As cold from rivers, heat from sun, and spray 
From waves of ocean, eater-out of walls 
Around the coasts. Nor ever cease to flit 
The varied voices, sounds athrough the air. 
Then too there comes into the mouth at times 
The wet of a salt taste, when by the sea 
We roam about; and so, whene'er we watch 
The wormword being mixed, its bitter stings. 
To such degree from all things is each thing 
Borne streamingly along, and sent about 
To every region round; and Nature grants 
Nor rest nor respite of the onward flow, 
Since 'tis incessantly we feeling have, 
And all the time are suffered to descry 
And smell all things at hand, and hear them sound. 
Besides, since shape examined by our hands 
Within the dark is known to be the same 
As that by eyes perceived within the light 
And lustrous day, both touch and sight must be 
By one like cause aroused. So, if we test 
A square and get its stimulus on us 
Within the dark, within the light what square 
Can fall upon our sight, except a square 
That images the things? Wherefore it seems 
The source of seeing is in images, 
Nor without these can anything be viewed. 
Now these same films I name are borne about 
And tossed and scattered into regions all. 
But since we do perceive alone through eyes, 
It follows hence that whitherso we turn 
Our sight, all things do strike against it there 
With form and hue. And just how far from us 
Each thing may be away, the image yields 
To us the power to see and chance to tell: 
For when 'tis sent, at once it shoves ahead 
And drives along the air that's in the space 
Betwixt it and our eyes. And thus this air 
All glides athrough our eyeballs, and, as 'twere, 
Brushes athrough our pupils and thuswise 
Passes across. Therefore it comes we see 
How far from us each thing may be away, 
And the more air there be that's driven before, 
And too the longer be the brushing breeze 
Against our eyes, the farther off removed 
Each thing is seen to be: forsooth, this work 
With mightily swift order all goes on, 
So that upon one instant we may see 
What kind the object and how far away. 
Nor over-marvellous must this be deemed 
In these affairs that, though the films which strike 
Upon the eyes cannot be singly seen, 
The things themselves may be perceived. For thus 
When the wind beats upon us stroke by stroke 
And when the sharp cold streams, 'tis not our wont 
To feel each private particle of wind 
Or of that cold, but rather all at once; 
And so we see how blows affect our body, 
As if one thing were beating on the same 
And giving us the feel of its own body 
Outside of us. Again, whene'er we thump 
With finger-tip upon a stone, we touch 
But the rock's surface and the outer hue, 
Nor feel that hue by contact- rather feel 
The very hardness deep within the rock. 
Now come, and why beyond a looking-glass 
An image may be seen, perceive. For seen 
It soothly is, removed far within. 
'Tis the same sort as objects peered upon 
Outside in their true shape, whene'er a door 
Yields through itself an open peering-place, 
And lets us see so many things outside 
Beyond the house. Also that sight is made 
By a twofold twin air: for first is seen 
The air inside the door-posts; next the doors, 
The twain to left and right; and afterwards 
A light beyond comes brushing through our eyes, 
Then other air, then objects peered upon 
Outside in their true shape. And thus, when first 
The image of the glass projects itself, 
As to our gaze it comes, it shoves ahead 
And drives along the air that's in the space 
Betwixt it and our eyes, and brings to pass 
That we perceive the air ere yet the glass. 
But when we've also seen the glass itself, 
Forthwith that image which from us is borne 
Reaches the glass, and there thrown back again 
Comes back unto our eyes, and driving rolls 
Ahead of itself another air, that then 
'Tis this we see before itself, and thus 
It looks so far removed behind the glass. 
Wherefore again, again, there's naught for wonder 
In those which render from the mirror's plane 
A vision back, since each thing comes to pass 
By means of the two airs. Now, in the glass 
The right part of our members is observed 
Upon the left, because, when comes the image 
Hitting against the level of the glass, 
'Tis not returned unshifted; but forced off 
Backwards in line direct and not oblique,- 
Exactly as whoso his plaster-mask 
Should dash, before 'twere dry, on post or beam, 
And it should straightway keep, at clinging there, 
Its shape, reversed, facing him who threw, 
And so remould the features it gives back: 
It comes that now the right eye is the left, 
The left the right. 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 of 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 of 
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 set 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, diversely 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.
