How does Tiresias contribute to Creon's development as a tragic hero?

Tiresias, the blind prophet in Sophocles' "Antigone," serves as a crucial catalyst for Creon's development as a tragic hero by confronting him with the consequences of his stubbornness and hubris. Through Tiresias's prophetic insights, Creon is forced to confront the moral and ethical implications of his decisions, particularly his refusal to bury Polyneices and punish Antigone. This interaction highlights Creon's initial rigidity and leads to a moment of self-realization, showing his potential for growth. Ultimately, Tiresias's warnings emphasize the tragic cost of Creon's pride, as he struggles with the repercussions of his choices, which embodies the essence of a tragic hero.
