Looking For Pope Joan

In a medieval mystery of the Catholic Church lies evidence of a woman pope, with clues buried in ancient parchment, artwork and writings, even in tarot cards and a bizarre chair once used in a Vatican ritual.

Was there a Pope Joan? A woman with nerve enough to disguise herself as a man and serve as pope for more than two years in the ninth century? It is one of the world's oldest mysteries. Her story first appeared in histories written by medieval monks, but today the Catholic Church dismisses it.
