The contexts of Greek tragedy were used as methods of citizen education for Athenians and other Greek citizens. In this hypothesis, the educational approach is needed to analyze the authors and tragedies in Athens. Sophocles is well known as a master of Greek tragedies, and even famous philosopher Aristotle highly praised him in Poetika. Furthermore, Antigone has been an important and key piece of literature in the field of philosophy and feministic studies. The two main characters, Antigone and Creon, are very different in two ways. The first way is their understanding of law and customs(nomos), which are their moral principles for their decisions. Antigone buried her brother, Polineikes, because she believed that he had the right to rest in Hades even though he triggered a civil war in Thebai. On the other hand, Creon proclaimed, "anyone who buried this traitor would be killed by stoning." Antigone's moral principles are based on natural law; however, Creon blamed Zeus, which is the background of the natural laws, for he believed in his power, authority and reason to rule Thebai. The second way they are different is their attitudes after they confront their fates. Antigone walked into a stone tomb by herself. Also, she was very pragmatic in that she decided to leave her home in Thebai. In Creon's rule, laws and customs were different compared to laws and customs of Thebai. Therefore, the laws and customs under Creon’s rule were not customary and familiar to Antigone. She made a decision to transfer her conformity polis. On the other hand, Creon’s greediness has been escalating. He was stopped by his hubristic behavior after he lost his son and wife for their suicides. Antigone is well known to its various approaches of analyses of the text. It also has multiple educational implications. In the rapid changing society, we should reconsider the meaning and implications of the Classics.
