Defining the Proscenium
Architectural Frame
The proscenium is fundamentally the virtual vertical plane of space within a theatre, typically framed by a physical proscenium arch. This arch, whether truly curved or rectangular, serves as the aperture through which the audience observes the stage action. It delineates the performance space, separating the world of the stage from the audience's perspective.
The Fourth Wall Concept
This architectural feature establishes the concept of the "fourth wall"โan invisible barrier that divides the actors and their stage-world from the audience. When the stage curtain is lowered, the proscenium arch gains a tangible reality, physically concealing the stage from view and reinforcing this conceptual separation.
Spatial Distinction
Structurally, a proscenium stage is distinct from thrust or arena stages. The proscenium arch creates a unified, frontal viewing angle for the audience, simplifying the staging by allowing performers to focus their attention in one direction. This design also facilitates the efficient hiding of stagecraft elements in the wings or flyspace.
Ancient Roots
Hellenistic Greek Theatre
In later Hellenistic Greek theatres, the proskenion (ฯฯฮฟฯฮบฮฎฮฝฮนฮฟฮฝ) was a narrow, raised stage where solo actors performed. The chorus and musicians occupied the orchestra below. The skene, a building behind the stage, often supported painted scenery and evolved into an elaborate structure. While the proskenion was a performance area, it lacked the defining proscenium arch of later eras.
Roman Theatres
Roman theatres adapted Greek designs. The stage area in front of the scaenae frons (the elaborate stage building) was called the pulpitum. The vertical front dropping from the stage to the orchestra floor, often decorated, was known as the proscaenium. This emphasized the stage's frontality, offering the audience a restricted, unified view from the front, unlike the more open Greek stages.
Visual Context: Roman Theatre
An illustrative depiction of a Roman theatre, such as the one in Bosra, Syria, highlights key architectural elements. The diagram typically shows the scaenae frons, orchestra, and cavea (seating area). The proscaenium is identified as the front part of the stage structure, distinct from the later concept of a proscenium arch.
The Dawn of the Arch
Teatro Olimpico: An Exception
The Teatro Olimpico in Vicenza (1585), an academic reconstruction of a Roman theatre, is notable for its lack of a proscenium arch. It features a plain proscaenium fronting the stage, but the audience and performance spaces are integrated without a separating arch, reflecting a direct emulation of Roman design principles.
Visual Context: Teatro Olimpico
Views of the Teatro Olimpico reveal its unique stage design. The seating area and stage are juxtaposed, with no proscenium arch dividing them. The central archway within the scaenae frons, while decorative, was too small to function as a modern proscenium arch and was part of the backdrop, not a frame for the entire stage.
Early Proscenium Use
While the Teatro Olimpico stood apart, evidence suggests the proscenium arch was already in use by the mid-16th century. Engravings from a 1560 production in Siena indicate its presence, marking a significant shift towards framing the stage as a distinct visual entity for the audience.
Baroque Evolution
Teatro Farnese: The First True Arch
The Teatro Farnese in Parma (1618) is recognized as the earliest surviving permanent theatre to feature a true proscenium arch. This architectural element, referred to by Italians as a "boccascena" (scene mouth), served as a picture-frame, clearly delineating the stage and separating the audience from the performance.
The Orchestra Pit
During the Baroque era, the introduction of an orchestra pit for musicians significantly altered the perception of the proscaenium. The barrier screening the pit became the new visual boundary for the audience, often painted black to minimize its prominence, while the original Roman proscaenium lost its architectural emphasis.
Visual Context: San Francisco Opera House
Modern proscenium theatres, like the War Memorial Opera House in San Francisco, showcase the grandeur of the proscenium arch. Often elaborately decorated, it serves as the primary frame for the stage curtains and the performance space, with the area below (the Roman proscaenium) typically de-emphasized.
Clarifying Terminology
Teatro Olimpico Misinterpretations
Confusion has arisen regarding the Teatro Olimpico's design. Some scholars have incorrectly identified its scaenae frons or its central archway as the precursor to the modern proscenium arch. However, contemporary illustrations confirm that action occurred primarily in front of the scaenae frons, not framed by its central opening.
Linguistic Challenges
The evolution of theatrical terminology presents linguistic challenges. The Italian word for the scaenae frons, "proscenio," represents a significant semantic shift from its Latin origin. This divergence necessitates precise translation to maintain clarity between classical Roman stage elements and later Renaissance and Baroque architectural innovations.
The Proscenium's Role
Creating a Visual Window
The proscenium arch functions as a "window" framing the stage, offering a consistent viewing perspective for the entire audience. This design allows performers to concentrate their performance towards the audience without needing to constantly adjust their position for visibility from all angles.
Concealment and Stagecraft
This architectural framing simplifies the management of stagecraft. Elements not intended for audience view, such as set pieces, off-stage performers, or theatre technology, can be effectively hidden in the wings or the flyspace above the stage, outside the visual "window" of the proscenium.
The Fourth Wall and Performance
The concept of the "fourth wall" is intrinsically linked to the proscenium. When a performer directly addresses the audience, breaking this invisible barrier, it is often referred to as "breaking the proscenium" or "breaking the fourth wall," a deliberate theatrical device.
Alternative Staging Forms
Traverse Stage
In a traverse stage setup, the audience is seated on two opposite sides of the stage, viewing the performance from across its length. This creates a linear performance space with distinct audience perspectives.
Thrust Stage
A thrust stage extends into the audience, surrounded on three sides (or 270 degrees). This configuration, sometimes called a "three-quarter round" or "apron stage," can be a modification of a proscenium theatre, bringing the performance closer to the audience.
Theatre in the Round
In theatre-in-the-round, the stage is completely surrounded by the audience. This setup necessitates performers engaging with the audience from all sides, creating a highly immersive experience.
Black Box Theatre
A black box theatre is a versatile, often minimalist spaceโtypically a large, dark rectangular room. Its flexible seating and staging arrangements allow for complete adaptation to the specific needs of a production.
Site-Specific Theatre
Site-specific or environmental theatre breaks conventional staging by integrating the performance with its location. The audience and stage may blend, or be arranged in numerous, unconventional configurations, making it distinct from traditional theatre layouts.
