Final answer:
Italian theatrical scenery evolved from a formal architectural style to a Baroque style, known for its ornateness and dynamic movement, influencing theatre design across Europe.
Step-by-step explanation:
As Italian theatrical scenery advanced, it moved away from a Formal/Architectural look into a more Baroque look, characterized by ornate details and dynamic movement. This evolution aligned with the broader artistic trends of the Baroque period in the 1600s, which echoed in the design of theatre spaces and scenery. Italian theatrical innovations, such as Serlio's single-point perspective settings, the development of the proscenium arch, and the creation of wing and drop scenery, indicate a shift towards more opulent and visually engaging designs, moving away from the Neo-Classic style that was focused on replicating the architectural features of ancient Greece and Rome. The Baroque style emphasized grandeur and emotional intensity, which translated into the rich and elaborate scenes on stage, setting a standard that influenced theatres across Europe, including the Broadway stages.
