Sybaris was an important city of Magna Graecia. The city was founded in 720 BC by Achaean and Troezenian settlers. Sybaris amassed great wealth thanks to its fertile land and busy port. Its inhabitants became famous among the Greeks for their hedonism, feasts, and excesses, to the extent that 'sybarite' and 'sybaritic' have become bywords for opulence, luxury and outrageous pleasure-seeking.
In 510/09 BC the city was subjugated by its neighbor Kroton and its population driven out. Sybaris became a dependent ally of Kroton, but Kroton again besieged the city in 476/5 BC, probably resulting in another victory for Kroton. Two attempts to reoccupy the city failed around 452/1 BC and 446/5 BC when the remaining Sybarites were again expelled by the Krotoniates. After a call for help the Sybarites reoccupied their city later in 446/5 BC with the assistance of new settlers from Athens and other cities in the Peloponnese. This coexistence did not last long: the Sybarites got into a conflict with the new colonists and were ousted for the last time in the summer of 445 BC. In sum, the city saw a total of five periods of occupation separated by expulsion. The new settlers then proceeded to found the city of Thurii in 444/3 BC, a new colony which was built partially on top of the site of Sybaris. The surviving Sybarites founded Sybaris on the Traeis.
The ruins of Sybaris and Thurii became forgotten as they were buried by sediment from the Crati river over time. The ruins were rediscovered and excavated in the 1960s by Donald Freeman Brown. Today they can be found southeast of Sibari, a frazione in the comune of Cassano allo Ionio.
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.
