Bernini's most famous sculpture is "St. Theresa in Ecstasy". It tells the story of a saint who had a vision of an angel. Her vision was so beautiful that she fainted. Bernini has sculptured the vision, with St. Theresa lying on a cloud with the laughing angel in front of her. Their robes are blowing around, and it is hard to believe that the whole scene, which is set against a wall, is not really floating. Bernini did not just design the statues. He also designed the walls of the chapel around it, which is like a stage-set, made of beautifully patterned marble. Against another wall, he carved a balcony and several white marble people looking at the scene. They are members of the family that paid for the chapel.
