The Haunting Ghost Story Of Olimpia Maidalchini
In the modern-day United States, the First Lady has very little political power. But apparently in Ancient Rome, it was the sister-in-law of the Pope who really ruled the roost (especially considering she was also his mistress, via The Guardian). Olimpia Maidalchini Pamphilij was an incredibly intelligent, somewhat manipulative social climber of the 17th century. She was, in fact, sister-in-law to Pope Innocent X, by marriage to his brother, Prince Pamphilio Pamphilij (via Eyes of Rome).
