[1] The parodos is a large passageway affording access either to the stage (for actors/ singers) or to the orchestra (for the chorus) of the ancient Greek theater.
Scholars note that eisodos was an older term for the passageway while parodos was widely used by writers from Aristotle onwards.
[4] Parodos also refers to the ode sung by the chorus as it enters and occupies its place in the orchestra.
It is an important part as it defined the chorus, provide information about the plot, and assist or fight the protagonist.
[4] The parodos is highly commemorated in Athenian artifacts that show choral performance.
