The main action is all taken within the stage which Greeks called it the orchestra. They all have the finest seats at the bottom and the cheap seats at the top. They have many entrances so that people can enter and exit out quickly. The seats are usually curved around the stage with stadium seating so that audiences have a good view of the show. Just like the Colosseum, the stage of arenas in the western world can be changed according to the performance so that basketball game, concert, circus, ice skating, and etc can be performed on this one structure. These buildings are all influenced by the Epidaurus Theater and The Colosseum.
The Parthenon, Pantheon, and The Temple of Fortuna Virilis are also a classic architecture that Western art has been influenced by. .
The Parthenon was made of the classical Doric style with ionic columns on the side. There is an exact geometric regularity in the design of this great structure (133). It looks classical, but it is anticlassical in that the columns lean inward one and half inches. This was done because Parthenon was supposed to be seen from far away. It was a sacred place where people only went on special days. Parthenon is an example of a classical artistic inheritance in Western art in that it gave them the bases for classical form and structure. The columns on the front were used for decoration and for holding up the ceiling. The triangle cornice is a common form we see in many buildings that was influenced by the Greek and Roman architecture. It is a straight, geometric looking structure that is very classical in form. The idea that a building was made for honoring god is also same as in the Western architecture.
The Temple of Fortuna Virilis was a Roman structure built in the late 2nd century. It has classical form but also anticlassical. It has Ionic columns, but some of them are pilasters, which makes it anticlassical. It was located near or in middle of the town unlike the Parthenon.
