Bernini Built This to Humiliate His Rival

For nearly 400 years, one of Rome's most visited squares has been hiding a secret that most tourists walk straight past. When Pope Innocent X commissioned the Fountain of the Four Rivers in 1648, he made one thing clear — Bernini was not to be involved. What followed was one of the most audacious power moves in the history of art, a rivalry so bitter it was carved into the marble itself, and a joke so perfectly executed that Rome is still talking about it four centuries later. In this video, we break down the story behind the Fountain of the Four Rivers, the vicious rivalry between Bernini and Borromini, and the detail hidden in plain sight that has divided art historians ever since.
