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.
