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 w
