[Nor were painters the only ones who saw the mirror as a symbol.] [Shakespeare's] works are filled with references to mirrors, not only for vanity but for use in self-examination, ... In fact, there's a famous scene in 'Richard II,' when he's losing his kingship, he calls for a mirror, looks into it and asks, 'Why don't I look any different?' Then he smashes it on the stage and says, 'That's my old identity.' Mark Pendergrast
