At the beginning of 17th century theaters had moved indoors and began to resemble the arrangement we see most frequently today, with a stage separated from the audience by a proscenium arch. This coincided with a growing interest in scenic elements painted in perspective, such as those created by Inigo Jones, Nicola Sabbatini and the Galli da Bibiena family. The perspective of these elements could only be viewed properly from the center back of the auditorium, in the so-called "duke's chair." The higher one's status, the closer they would be seated to this vantage point, and the more the accurately they would be able to see the perspective elements.
