Upon sneaking in from her brother's burial, Antigone tells the Nurse that she has come from a "gray world." Like many of Anouilh's heroines, Antigone wanders in this gray "nowhere," a world beyond the "post card" universe of the waking. This world is breathless with anticipation: it doubles the stage, set apart from the human world, upon which Antigone's tragedy will ensue. At the same time, the world of the living does not lie in wait for Antigone: she is meant to pass onto another.
Anouilh symbolizes Antigone's transcendence of state power with Creon's assault on her person during their confrontation. Enraged by her proud defiance and his inability to sway her, Creon seizes Antigone and twists her to his side. The immediate pain passes, however: Creon squeezes to tightly, and Antigone feels nothing. Thus Antigone passes beyond the reach of state power and the realm of men.
As the Chorus remarks, Queen Eurydice's function in the tragedy is to knit in her room until she dies. She is Creon's final lesson, her death leaving him utterly alone. In the report of her suicide, Eurydice will stop her knitting and the stab herself with her needle. The end of her knitting is the end of her life, evoking the familiar Greek myth of the life-thread spun, measured, and cut by the Fates.
