In the 9th cent. drama returned to the Western world in the form of mystery and miracle plays, which were performed in churches. Usually stories from the Bible, such plays were first acted by priests, their stage consisting of different platform sets arranged in rows along the side of the nave of the church. One effect of the church setting was to create a close relationship between audience and performer.
Later these plays were moved out of the church into the street, where the platform sets were arranged around an area in which the audience could stand or move from place to place in a prescribed order. Acting took place either on the platforms, in front of them, or between them, depending on the need. The platforms were often elaborate in their decoration and stage machinery. With the shift to the streets, acting was transferred from the priesthood to the amateurs of the guilds or professional players.
