The so-called Temple of Demeter (the remains of which are located below of the church of San Biagio) can be dated between 480 and 470 BCE. This temple offers an interesting example of distylous building in antis, i.e.without an outer colonnade. It has a simple cella preceded by a pronaos (ante-room) with two columns.
Still preserved from the original structure are the base (30 by 13 m approx and partly visible), the outer cella walls and the wall between the cella and the pronaos. These remaing parts have been incorporated in the medieval church dedicated to St. Biagio. The beautiful water spouts in the shape of lion’s heads from this building can still be seen in the Regional Archaeological Museum of Agrigento in the room dedicated to architectural sculptures.
The Temple of Demeter in the classical period was part of a temenos, a sacred enclosure that included other adjacent structures, such as two small round altars with a central bothros or holy well. Inside, archaeologists found kernoi (ritual vessels linked to the cult of Persephone) and the remains of busts that must have represented Demeter.
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.
