Teiresias is a blind harbinger. He makes Creon abolish the verdict of Antigone, as he sees an inevitable disaster if he will not release a girl. When Creon insults Teiresias, the seer prophesies that the gods will punish Creon for Antigone's death by taking the life of his child. Teiresias returns Creon's trash talk skillfully, but he continues to hammer home the point that Creon's actions - refusing to give his nephew proper burial rites and entombing Antigone alive in a cave - violate tradition, decency, and even the order of nature itself, and will have fatal consequences.
