Who were the ancestral Sonoran Desert people? Archeological evidence suggests they may have descended from an earlier hunting and gathering “Archaic” culture that began in this area around 5,500 B.C.E. Over time, as the area grew hotter and drier, wild plants and animals became less abundant.
This is an artist's depiction of the Casa Grande ('Great House') and its surrounding compound as it may have appeared around 1350 C.E. One of the largest prehistoric structures ever built in North America, its purpose remains a mystery.
Archeologists have discovered evidence that the ancestral Sonoran Desert people who built the Casa Grande also developed wide-scale irrigation farming and extensive trade connections which lasted over a thousand years until about 1450 C.E. Archeologists call a site where there are earthen buildings, red on buff pottery, and extensive canals 'Hohokam' but this is not the name of a tribe or a people. Years of misunderstanding have confused the ancestors of the O'Odham, Hopi, and Zuni people with the name Hohokam, which is not a word in any of their languages nor the name of a separate people.
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.
