t 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
