Quattro Fiumi and Sant’Agnese in Agone

‘Quattro Fiumi and Sant’Agnese in Agone’, translated into English: ‘Four rivers and St Agnes in agony’. Sounds terrible. But if you recall the film Angels and Daemons, there was a scene with a professor rescuing a cardinal in a fountain designed by Bernini. The scene takes place in Rome at Piazza Navona. The fountain is called Four Rivers and is indeed created by Bernini. It is located in front of a church, the patron of which is St Agnes in Agony.
