Vanity was born when the mirror was discovered. That’s what the Chicago Record wrote in 1895, around the time when mirrors became a household item. People (and especially women) were condemned for looking in the mirror, and accused of being sinful. But then the mirror altered the way we think about vanity altogether — and forever changed the way we look at ourselves. In this episode, we explore the history of the mirror, the history of vanity, and what it can teach us about today’s obsession over selfies.
