Explain the purpose and importance of the parados in the context of its intended audience, the ancient greeks.

 every ancient Greek tragedy, the first time we hear the Chorus is when they sing their parados or entry song. Parados looks a little bit like the modern word "parade," right? This is probably no accident. When the Chorus performed the parados they would "parade" in, singing and dancing with much fanfare. The actual word "parados" comes from the name of the corridor or archway through which the Chorus first entered. 

In Antigone, Sophocles uses the parados to give back-story. The Chorus sings all about the terrible battle that has just been fought. We also get the sense that the people of Thebes are furious at Polyneices for betraying and attacking them. This helps to strengthen Creon's position about the traitor's burial. 

Overall, the parados in Antigone is a joyful celebration of victory. This is, of course, highly ironic. The audience has just watched the prologue, in which Antigone declares her intentions to defy the state. Though Thebes has just defeated an external enemy, the new order represented by Creon will be challenged almost immediately by an enemy from within.
