Engendered, and perpetually flow off
From things and gliding pass away....

As chiefly mirrors, have been set before it,
Nothing of this sort happens. For it can't
Go, as through glass, nor yet be rent- its safety,
By virtue of that smoothness, being sure.

'Tis therefore that from them the images
Stream back to us; and howso suddenly
Thou place, at any instant, anything
Before a mirror, there an image shows;
