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.
