Themes are the fundamental and often universal ideas explored in a literary work.
Fate was of great concern to the Greeks, and its workings resonate through many of their myths and texts. We see countless characters who go to great lengths in attempts to alter fate, even if they know such an aim to be futile. The inability of any mortal or immortal to change prescribed outcomes stems from the three Fates: sisters Clotho, who spins the thread of life; Lachesis, who assigns each person’s destiny; and Atropos, who carries the scissors to snip the thread of life at its end. These three divinities pervade all the stories of Greek myth, whether they be stories of gods, goddesses, demigods, heroes, or mortals and regardless of the exploits recounted. Nothing can be done to alter or prolong the destiny of one’s life, regardless of the number of preparations or precautions taken. This inflexibility applies just as much to Zeus as to the lowliest mortal, as we see in Zeus’s hounding of Prometheus to divulge the name of the woman who will bear the offspring that one day will kill him.
Though this lesson is somewhat consoling—the way of the world cannot be bent to match the whims of those in authority—it is also very disturbing. The prospect of free will seems rather remote, and even acts of great valor and bravery seem completely useless. The myths provide an interesting counterpoint to this uselessness, however. In virtually all the stories in which a character does everything in his power to block a negative fate, and yet falls prey to it, we see that his efforts to subvert fate typically provide exactly the circumstances required for the prescribed fate to arise. In other words, the resisting characers themselves provide the path to fate’s fulfillment.
A perfect example is the king of Thebes, who has learned that his son, Oedipus, will one day kill him. The king takes steps to ensure Oedipus’s death but ends up ensuring only that he and Oedipus fail to recognize each other when they meet on the road many years later. This lack of recognition enables a dispute in which Oedipus slays his father without thinking twice. It is the king’s exercise of free will, then, that ironically binds him even more surely to the thread of destiny. This mysterious, inexplicable twinning between will and fate is visible in many the stories and philosophical treatises of the Greeks.
Aeschylus’s Oresteia, Sophocles’ Oedipus trilogy, Euripides’ plays, and Homer’s two great epics all demonstrate the irreparable persistence of bloodshed within Greek mythology that leads to death upon death. The royal house of Atreus is most marked in this regard: the house’s ancestor, Tantalus, inexplicably cooks up his child and serves him to the gods, offending the deities and cursing the entire house with the spilling of its blood from generation to generation. We see the curse manifest when Atreus himself kills his brother’s son and serves him up—an act of vengeance for wrong-doing done to him. Atreus’s son, Agamemnon, then sacrifices his own daughter, Iphigenia, as he has been told it will procure good sailing winds for the Greeks to start off to Troy. Rather, this deed leads his wife, Clytemnestra, to kill him on his first night home, with support from his cousin Aegisthus, who is in turn avenging Atreus’s crimes. Last but not least, Orestes, the son of Agamemnon and Clytemnestra, comes back to kill his mother and Aegisthus. Only two members remain in the House of Atreus: Orestes and his sister Electra. Everyone else has been foully murdered in this bloody chain of events.
Though these characters have brought terrible violence upon those to whom they owed bonds of love and loyalty, they are still not wholly condemnable. Orestes knows that he will incur the wrath of the Furies and the gods in committing matricide. As terrible as matricide is, Orestes would be even more in the wrong if he let his father’s death go unpunished. Clytemnestra no doubt follows a similar rationale, as she cannot allow Agamemnon’s sacrifice of their daughter to stand unavenged. Even this is not the beginning of the chain: Agamemnon felt he had no choice but to sacrifice Iphigenia, since his only other option was to break the oath he made to Menelaus years before. Indeed, the whole line of Atreus is cursed with such irresolvable dilemmas, the outcome of divine anger at Tantalus’s horrific and unprompted sacrifice of his son. In this slippery world of confusing and conflicting ethics, the only certainty is that bloodshed merely begets more bloodshed.
In many myths, mortals who display arrogance and hubris end up learning, in quite brutal ways, the folly of this overexertion of ego. The Greek concept of hubris refers to the overweening pride of humans who hold themselves up as equals to the gods. Hubris is one of the worst traits one can exhibit in the world of ancient Greece and invariably brings the worst kind of destruction.
