In the staging of the ghost scenes, however, there seems to have been conformity. The one non-Shakespearean play which portrays ghosts, The Devil’s Charter, describes the staging exactly.
[A devil] goeth to one doore of the stage, from whence he bringeth the Ghost of Candie gastly haunted by Caesar persuing and stabing it, these vanish in at another doore.
Later in the same scene,
He bringeth from the same doore Gismond Viselli, his wounds gaping and after him Lucrece undrest, holding a dagger fix’t in his bleeding bosome: they vanish.
[Sig. G2r]
Later in the play,
The Divell bringeth forth from the doore Lucreciaes Ghost, and after her the ghost of Candie stabbed.
[Sig. M2r]
Stage directions early in the scenes place these actions forward on the stage so that there is no doubt that the stage doors are the ones described as the entries for the ghosts.
