Bizarre, extravagant, irregular like the flawed pearl after which it would take its name. Baroque art leaves the circle and marries the oval, moves away from the measure and looks for optical illusionism. Theater becomes part of architecture, realism is placed at the service of scenographic effects. The abundant decoration hides technical data to be hidden from the observer’s eye and at the same time creates continuity between the stage and the audience. The spectator enters the masterpiece.
