The structure of the Elizabethan theater was naturally imitated from its chief predecessor, the inn-yard. There, under the open sky, opposite the street entrance, the players had been accustomed to set up their stage. About it, on three sides, the ordinary part of the audience had stood during the performance, while the inn-guests and persons able to pay a fixed price had sat in the open galleries which lined the building and ran all around the yard. In the theaters, therefore, at first generally square-built or octagonal, the stage projected from the rear wall well toward the center of an unroofed pit (the present-day 'orchestra'), where, still on three sides of the stage, the common people, admitted for sixpence or less, stood and jostled each other, either going home when it rained or staying and getting wet as the degree of their interest in the play might determine. The enveloping building proper was occupied with tiers of galleries, generally two or three in number, provided with seats; and here, of course, sat the people of means, the women avoiding embarrassment and annoyance only by being always masked. Behind the unprotected front part of the stage the middle part was covered by a lean-to roof sloping down from the rear wall of the building and supported by two pillars standing on the stage. This roof concealed a loft, from which gods and goddesses or any appropriate properties could be let down by mechanical devices. Still farther back, under the galleries, was the 'rear-stage,' which could be used to represent inner rooms; and that part of the lower gallery immediately above it was generally appropriated as a part of the stage, representing such places as city walls or the second stories of houses. The musicians' place was also just beside in the gallery.
