THE THEATRE. The theatre was a large building in a Greek theatre type, 300 feet wide, was protected with almost all of its architectural elements and with its cavea leaning against the slope of a hill. The first building phase built at the travertine blocks and has a small scaenae dated to the 1st century AD. It was damaged during the earthquake in 60 AD, and the reconstruction was begun during Flavians. It was still under construction during the Hadrianic age (117-138 AD) and was finished during the severians (206 AD). Its cavea has 50 seating rows and was divided 7 parts with 8 stairs. Diazoma took place in the middle of the cavea. Vaulted passages led to vomitorium which were on both sides. In the middle there was the box of the administrator and the orchestra which was surrounded by the front walls of the stage. The wall was 3.66 m. high having 5 doors and 6 niches. In front of them 10 marble columns took place. The seashell motives were carved on the top of the columns. On the walls behind the stage there were 3 different rows of columns. The lower row of the columns had octagonal bases. Amongst the columns there were the sculptors of the four goddesses such as Hera., Aphrodite, Demeter and Persephone. On the west part of the theatre there was a latrine (public toilettes). The friezes in the theatre had depicted the mythological scenes such as the birth of Apollo and Artemis; the ritual scenes; the processions of Dionysos, Satry and the Maenads; the music contest between Apollo and Marsyas; the battle between the gods and the giants; the abduction of Persephone by Hades to the Underworld; and also several festivals which were held in Hierapolis and the coronation of Emeror Septimius Severus who had supported the restoration of the theatre. The friezes of Hierapolis had a close resemblance to the friezes of theatres of Perge, Side and Nysa.
