Mirrors enlarge spaces, they double and reflect, and at night they reveal eerie shadows standing behind you. Mirrors achieve what paintings have been struggling to achieve since the discovery of perspective: their images are a planar phenomenon that revels in realistic depth.
There ought to be something more to the silvery surfaces than physics; they ought to be a gateway to another world.

Narcissus dies in love with his image, unable to reach it, unable to hold it—the cost of hubris.
Snow White imbues Mirror, Mirror with the power of taking an instantaneous beauty census and reporting it, but no cross-over occurs.
Lewis Carroll’s Through the Looking Glass (1871), however, goes all the way and sends Alice into the Looking-glass House. Moments before she steps through, she stands on the mantlepiece in front of the huge wall-mirror gazing inside:
You can just see a little peep of the passage in Looking-glass House, if you leave the door of our drawing-room wide open: and it’s very like our passage as far as you can see, only you know it may be quite different on beyond.
