Final answer:
Eurydice, after hearing of Haemon and Antigone's deaths, kills herself in despair and curses Creon with her dying breath.
Step-by-step explanation:
After the Messenger Relayed the News
After the messenger relayed the news about Haemon and Antigone to Eurydice, she was overwhelmed with grief upon learning of her son's death. Eurydice went to the altar to pray but then, stricken with sorrow, she took her own life with a keen-edged sword.
Before dying, she expressed her despair, mourning her previously lost son Megareus, and with her last breath, she cursed Creon for his role in Haemon's death. This tragic sequence added to the dark tone of the play Sophocles' Antigone, driving home the consequences of Creon's unyielding enforcement of the law.
