The Villa of the Mysteries (Villa dei Misteri) is a well-preserved suburban Roman villa on the outskirts of Pompeii, southern Italy, famous for the series of frescos in one room, which are usually thought to show the initiation of a young woman into a Greco-Roman mystery cult. These are now probably the best known of the relatively rare survivals of Ancient Roman painting. Like the rest of the Roman city of Pompeii, the villa was buried in the eruption of Mount Vesuvius in 79 and excavated from 1909 onwards (long after much of the main city). It is now a popular part of tourist visits to Pompeii, and forms part of the UNESCO World Heritage Site at Pompeii.
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.
