Most things which appear in a mirror duplicate what can be seen in its immediate vicinity…. But for each of us there is one item whose appearance is inescapably confined to the mirror, because there is no way of seeing it except in a mirror…. For all these reasons, the mirror, in art as in life, has assumed complex metaphorical significance, epitomising both the vice and vanity and the virtue of prudent self-knowledge.
