Rome, Villa Farnesina: The Hall of Perspectives, representing views of Rome. Frescoes by Baldassarre Peruzzi (1518-9). Detail with columns. It represents the ideal continuation of the ground floor loggias; through the imitation columns one can see various views: villages perched on rock, countryside views, and in the background, against an illuminated sky, is the city (The Holy Spirit Church, a Roman basilica, the porta Settimiana).
