The Chorus, being a group of women, was a crucial part of this production of Antigone. The fact that they death by the end. They were the bridge that connected Creon and Antigone involved with both of their downfalls. The way that this was shown was through costume and change of costume during the play. In the beginning masks, which hid their gender and emphasized their words, making what they said more important than who they were. They spoke to Creon with the masks removed, as humans, and they saw the horror of what Creon was doing.
By the time Antigone was sentenced to death, they were wearing vales showing their sorrow in what they were watching. They were bound to Antigone fighting the same fight she was, only internally. They could not voice this until she had died. Euyridice died in the Choragoss arms, unmasked she held a friend and felt the pain that the mask and vales kept them from. They were in the middle of the fight and watched it all happen, as each character died the masks fell, they became more human.
Until the final ode where they end the play all wiser and sadder. The Chorus was a friend to the women and an advisor to Creon. They tried to be both and only ended up getting hurt in the process. The Chours was the representation of the fight for women and the symbol of male power. They were the two opposites brought together a Ying and yang if you will. Their costumes represented what they were saying and they represented the play. Without them they play would not mean as much they were the chorus of women.
