2. Dynamic effects (such as a vista changes) or the continuity of a production can be obtained only by using a revolve. The use of slip-stages to achieve dynamic effects or
continued changes of scenes is not possible at the same
time as the disabling cyclorama is used (Fig. 4). When the
side stages must be changed, "technical" pauses are unavoidable.

background, new volumes have been added at the sides and
rear stage. Wood ceilings (now replaced by steel-reinforced
concretel preserved the rectangular form of cubic areas and
determined the time required to change this scenic complex.
This rectilinear form in turn was dictated by the construction
techniques of that time, affecting scenery shifting techniques.

3. The fact that the upper limits of the cyclorama are within
the sightlines of the spectator requires the masking of the
area above the proscenium arch (Fig. 5). Attempting to improve this by using a circular semi-cupola requires the elimination of the lines above the stage for which it provides

Toward the end of the last century, this Italian-type stage
was provided with a cyclorama and a semi-permanent fixed
decor, a foundation on which this method of investiture is
based (Fig. 2). The new element is a half-cylindrical surface, obviously added late as shown by its poor relation to
the rectangular form of the stagehouse interior. In spite of
more recent improvements in technical equipment, the Italianate stage still incorporates some serious faults.
1. The outer extent of the visible acting area is strictly
bounded by the cyclorama. Auxiliary areas (that is the side
and rear stages) assume a dependent technical character.
Shows with large dimensions attempt to overcome the cyclorama's limitations so as to obtain the sensation of unlimited
side and back space, and are compelled to give up the advantages of the cyclorama (Fig. 3). As a result difficult
problems are caused by variations in the height and in the
technical facilities of the auxiliary spaces.
