Aside from a single sketch of the "scaenae frons", Palladio left no plans as to what kind of scenery should be used onstage. His illustration of an idealized Roman "scaenae frons" for Barbaro's commentary on the writings of Vitruvius had shown perspective street views similar to those which would later be built in the Teatro Olimpico, but the sketch of the proposed "scaenae frons" for the Teatro Olimpico shows no such street scenes. The space behind the central archway and the doors to each side is blank.
