The supreme elegance of the theatre is visible also if we take a look inside the several orders of boxes and at the inside of the upper loggia. The dark wooden small rounded columns that delimit and support the boxes give rhythm to this section, intended for the eminent members of the audience, and turn the architectural elements into a musical score. Furthermore, each box is embellished, as is the lodge, with refined frescoes depicting imaginary landscapes, buildings in part real and in part invented, pastoral scenes, mythological episodes.
