The door to Medea's house remains closed for the entirety of the play and all of the events and speeches are delivered outside of the house. The door represents more than one metaphorical "barrier" in the play, perhaps most significantly the insurmountable divide that has developed between Medea and Jason, but it may also be seen to represent the divide between the foreigner (Medea) and the Greeks (everyone else), between Creon's rulership and true justice, or between truth and true-seeming rhetoric. When Jason commands his men to remove the bolts and open the door they never get a chance to do so: Medea appears above the stage in a flying chariot, carrying her dead children—the barriers will not, will never, be breached.
