Mosynopolis , of which only ruins now remain in Greek Thrace, was a city in the Roman province of Rhodope, which was known until the 9th century as Maximianopolis. The city of Maximianopolis appears in written sources from the 4th century on. Its fortifications were renewed by Byzantine emperor Justinian I, and it was later a base for operations by Emperor Basil II in his wars against the Bulgarians.
In the 11th century, the city was the center of a district (bandon) in the theme of Boleron, and Anna Komnene reports in her Alexiad that there were many Manichaeans living in Mosynopolis in the late 11th/early 12th centuries. The town was captured in 1185 by the Normans, while the monk Ephrem says that the city was captured in 1190 by Frederick I, Holy Roman Emperor. The Battle of Messinopolis, in which the Bulgarians defeated Boniface I, Marquess of Montferrat, took place nearby in 1207, and was speedily followed by the destruction of Mosynopolis by Tsar Kaloyan of Bulgaria.
Bishops of Maximianopolis in Rhodope were present at the 5th and 6th-century ecumenical councils of Ephesus (431), Chalcedon (451), and Constantinople II (553) and in another council of 459. From the 7th to the 9th centuries, the see is referred to as archiepiscopal, giving it autocephalous status.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
