• noun A raised platform on which theatrical performances are exhibited; the flooring in a theater on which the actors perform. In modern theaters the stage includes not only the part which can be seen from the auditorium, but also the spaces on each side, behind the prosceniumarch, which are used for shifting the wings or side-scenes, and are themselves called the wings. The part extending back from the orchestra to the proscenfum-arch is called the proscenium. That side of the stage which is on the extreme left of the spectator is called the prompt-side, because in theaters which have no prompt-box the prompter stands there. The corresponding position to the spectator's right is called the opposite-prompt-side (or, briefly, o.-p.-side). Half-way between the center and the promptside is the prompt-center, the corresponding position to the right being called the opposite-prompt-center (or, briefly, o.-p.-center). The stage is thus divided laterally into five parts, called in order the prompt-side, the prompt-center, the center, the o.-p.-center, and the o.-p.-side, and these designations extend through the whole depth of the stage, as well as up into the flies: thus the five ropes by which a dropscene is raised or lowered are known as the prompt-siderope, prompt-center rope, center-rope, etc. As regards depth, the stage is divided into entrances varying in number according to the number of the wings or side-scenes. That between the proscenium and the first wing is called on one side the first prompt-entrance, and on the other the first o.-p.-entrance. From the first wing to the next is the second prompt- or second o.-p.-entrance, and so on. Everything above the stage from the top of the proscenium-arch upward is called the flies, and includes the borders, border-lights, all needed ropes, pulleys, and cleats, the beams to which these are attached, and the fly-galleries, from the lowest of which the drop-scenes are worked. The ancient Greek theater in its original form, as developed in the fifth century b. c., had no raised stage, the actors appearing in the orchestra amid the chorus.
