The Coliseum is an elliptical building made to hold 50,000 spectators for sporting and theatrical events. It is four stories high with rings of arcades on the first three levels. The arches have attached three-quarter columns, Doric on the first level, Ionic on the second, and Corinthian on the third. The top story has Corinthian pilasters. From here a large awning, the vlarium, could be stretched across the entire amphitheatre. The Coliseum was constructed under three Flavian em perors, Vespasian, Titus, and Dominitan. More than any other single building, its construction details, engineering, and sense of power and authority speak to the Roman culture.
