An essential convention, characteristic of all Greek tragedy, is the chorus.
Members sing and dance a series of odes, supplying both variation and pageantry.
The play's dramaturg noted the principles behind the plots in Greek plays. Like so many other Greek authors, including Homer and Plato, Aeschhylus here explores and counterpoints the lexial range of dike, the Greek word for 'justice' both in the sense of divine justice ordained by Zeus, vendetta justice and 'an eye for an eye,' and legal justice obtained in an Athenian courtroom before a jury of peers. The Classical Greek Theatre Festival began in 1971 under the inspiration and leadership of the late Keith Engar, past chair of the University of Utah Theatre Department, and Jim Svendsen, who has served as classical consultant and dramaturg. The festival expanded in its numbers of performances, audiences reached, and, since 1984, state tour locations. In 1992, the festival was first invited to sites outside Utah.
