In The Twelve Caesars, Suentonius describes a law, a senatus-consulte (decree) by Augustus, which regulated the seating of spectators in performance venues. In response to disorderly conduct during a show, he ordered that all first tier places would be reserved for the senators, and that no freed slave or foreigner could sit there. Soldiers and non-soldiers were separated, and married men were assigned special seating. Women could only sit in the upper tier, and could not mix with men. A special tribune was reserved for the priestesses.
