* Oedipus Rex by Sophocles - This play explores themes of fate, free will, and the consequences of hubris (excessive pride). Oedipus, the King of Thebes, unwittingly fulfills a prophecy that he will kill his father and marry his mother.
* Antigone by Sophocles - This play examines the conflict between divine law and human law, and the importance of individual conscience. Antigone chooses to defy the King's decree and bury her brother, even though it means defying the law and facing death.
* Medea by Euripides - This play focuses on the themes of revenge, betrayal, and the destructive power of passion. Medea, a sorceress, seeks revenge on Jason, her husband, after he abandons her for another woman.
While these are the most commonly cited, there are many other great tragedies written by Athenian playwrights, including:
* Agamemnon by Aeschylus
* The Persians by Aeschylus
* The Bacchae by Euripides
* Electra by Sophocles
It's important to note that the concept of "greatness" is subjective and there is no definitive list of the "best" Athenian tragedies. However, the three mentioned above are consistently praised for their enduring power, timeless themes, and masterful storytelling.
