Orestes

← Encyclopedia

When the goddess in the Odyssey wants to stiffen the spine of a fatherless prince, she names Orestes. Three times in the poem’s opening books — through Athena in disguise, through the old horseman Nestor at Pylos, through Menelaus at Sparta — Telemachus is told to look at the son of Agamemnon and become his equal: a young man who came home, struck down his father’s killer, and won back his house and a lasting name. In Homer the deed carries no shadow. The killing of Aegisthus, the usurper who seized the throne and the queen, is held up as a clean act of filial duty, the thing a good son does. There is no madness in it, no pursuit, no court. Orestes is the avenger the tradition began by admiring.

The admiration did not survive contact with the tragic stage. Orestes is the son of Agamemnon and Clytemnestra: the prince who returns to Mycenae to kill his mother and her lover Aegisthus in vengeance for his murdered father, and who is then pursued for that killing by the Erinyes, the Furies who avenge the spilling of kindred blood. He is among the oldest named heroes in the tradition, but in the hands of the fifth-century poets his story turned from a model into the central case of a problem that family vengeance could not solve — a knot the gods themselves had tied.

The bind

The bind is exact, and it runs back through three generations of a cursed house. The line of Atreus carried an inheritance of atrocity: Atreus, Orestes’s great-grandfather, had killed his brother Thyestes’s children and served them to their father at a feast, and Aegisthus was the son Thyestes begot afterward to take the vengeance the curse demanded. Into that descending series Agamemnon adds his own act. Mustering the Greek fleet for Troy, he found the ships becalmed at Aulis; to raise a wind he sacrificed his daughter Iphigenia at the altar, trading a child for a war. Returning a decade later, the conquering king was murdered in his own hall by Clytemnestra, who had nursed that grief into a justice of her own, and by Aegisthus, who was already owed blood by the house that had butchered his brothers. Orestes, a child at his father’s death, was carried away — by his sister, in most tellings — and raised in Phocis in the house of Strophius, alongside Strophius’s son Pylades. He came back grown, the last living son of the murdered king.

Here the duties cross. The obligation to a slain father commands Orestes to avenge him; but in this house the murderer is the mother, and the only available avenging is matricide — which incurs the very pollution it answers and summons the very avengers it was meant to satisfy. Clytemnestra killed for Iphigenia. Orestes must kill Clytemnestra for Agamemnon. The next blow is already implied in the last, and the structure has no exit: every party can claim the right, every killing is at once an act of justice and a fresh murder, and the dead each leave an heir. This is the difference between the Homeric Orestes and the tragic one. Homer can praise the avenger because he holds Aegisthus in the foreground and lets the killing of the mother stay almost out of view; the tragic poets put Clytemnestra at the center of the act and force the audience to watch a son raise his hand against the woman who bore him. In the older telling the deed was simply heroic. The tragedians turned it into a trap in which every right action generates a new crime, and the chain of retaliation contains no point at which it can honestly stop — not by force, at any rate, because force is precisely what keeps it turning.

The Oresteia

The fullest treatment is the Oresteia of Aeschylus, three plays staged at the City Dionysia in Athens in 458 BCE, where the trilogy took first prize: Agamemnon, in which the king comes home to the axe; The Libation Bearers, in which Orestes and his sister at the tomb plan and accomplish the revenge; and The Eumenides, in which the consequence is at last brought before a tribunal. Across the three the killing passes from a private act in a darkened house to a public question debated in the open.

Orestes does not act alone or on his own judgment. He kills under the explicit command of Apollo, whose oracle ordered him to avenge his father and threatened him with horrors if he refused. The god has set him an impossible task and then, when the deed is done, is bound to defend him. The instant the blood is shed the Erinyes rise — ancient chthonic powers older than the Olympian order, daughters of Night or of the wounded Earth in different accounts, whose single office is to hound those who shed the blood of their own kin. They are less a punishment imposed from outside than the spilled blood made into a pursuing thing: the dead mother’s claim given shape, voice, and hounds. Orestes is driven mad and across the world before them. He flees first to Delphi, Apollo’s sanctuary on Parnassus, where the god purifies him of the stain by the prescribed rites. The cleansing settles nothing. The ghost of Clytemnestra rouses the sleeping Furies from the temple floor, and they take up the chase again: ritual purity, the play insists, does not extinguish the claim of spilled blood.

The resolution is invented rather than inherited. Orestes makes his way to Athens and clasps the ancient image of Athena, and the goddess, refusing to decide so grave a matter alone, founds a court — the Areopagus, the council on the Hill of Ares — and seats a jury of Athenian citizens to try the first case of homicide ever judged by law rather than by retaliation. The Furies prosecute; Apollo speaks for the defense; the question of whether a son may kill the mother who killed his father is argued in the language of advocacy, not vendetta. The votes are counted and the jury splits evenly. Athena casts the deciding ballot for acquittal. Orestes goes free. The Furies, robbed of their prey and enraged, threaten to blight the land — and Athena, by persuasion rather than force, turns them: offered an honored home and a perpetual cult beneath the city, they are transformed into the Eumenides, the Kindly Ones, the old engines of vengeance reseated as guardians of the very order that overruled them.

The sequence dramatizes a shift that historians of Greek religion read as a real one in the culture’s sense of how blood-guilt is discharged: from private revenge and the contagious pollution it spread, to the public institutions of the court and the rites of purification that could wash the killer clean. It was also pointed political theater. Four years before the trilogy, the reformer Ephialtes had stripped the aristocratic Areopagus of its broad guardianship of the state, leaving it chiefly the jurisdiction over homicide; the reform was violent — Ephialtes was murdered — and Aeschylus, founding that same court in the mythic past at Athena’s own hand and confining it to exactly the cases of killing it now still tried, set a charter myth across a fresh civic wound.

A myth that argues with itself

What Aeschylus closed, the next generation reopened. Sophocles and Euripides each returned to the matter and reworked it so divergently that the variants cannot be reconciled — which is the point. The myth was a frame for live ethical argument, not a settled account, and each poet used it to ask a different question.

Sophocles, in his Electra, centers the sister and stages the revenge as a clean triumph: Orestes returns with Pylades, the killings are carried through, and there is no aftermath of Furies, no trial, no Athena, no verdict on whether the matricide was just. The deed stands without a tribunal to weigh it. Euripides, in his own Electra, does the opposite, dragging the act down into squalor and remorse — the siblings left sickened by what they have done, the divine twins Castor and Pollux arriving at the end to pronounce the killing ill-advised even though Apollo had ordered it, and to dispose of the survivors: Electra to marry Pylades, Orestes to be tried at Athens. In his late Orestes of 408 BCE, Euripides abandons the Athenian resolution entirely. The action is set in Argos days after the matricide, Orestes wasted by madness and nursed by Electra, both condemned to death by stoning by the Argive assembly at the urging of Tyndareus, Clytemnestra’s father. The play spirals into a hostage plot against Helen and her daughter before Apollo descends to impose an ending no human action had earned. The trial that had been Aeschylus’s whole achievement is gone; what remains is a city ready to kill its own and a god patching the wreck from above.

Stain, friendship, and homecoming

Two threads carry Orestes beyond the theater and into the wider esoteric and religious imagination. The first is the matter of the stain itself. Behind the whole arc lies the conviction that the shedding of kindred blood leaves a pollution — a miasma, a contagion that clings to the killer like a physical defilement, that can travel from him into a household or a land and bring on plague, barrenness, and famine until it is lifted. The pollution is impersonal; it attaches to the deed and the doer regardless of intention or justification, which is why even a killing the gods commanded leaves Orestes unclean. To remove it the killer is not punished but cleansed, by rites in which the blood of a sacrificial animal is poured over his hands so that one blood washes away the other. Apollo’s purification of Orestes at Delphi is the paradigm case in Greek thought of a deed that marks the soul and a rite that lifts the mark — the idea that a person, however bloodied, can be made clean again. Aeschylus sets the two powers in deliberate tension: the rite cleanses Orestes’s hands, and the Furies keep coming anyway, as if to say that purification and adjudication answer different parts of the same wound and that neither alone is enough. That larger conviction — defilement as a state of the soul, and its washing-away as something more than penalty — runs forward into the broader doctrine of sin, where the same logic of stain and cleansing reappears in religions far from the Greek; in Orestes it stands in its sharpest dramatic form.

The second thread is the bond with Pylades, which antiquity made a byword for loyalty — the friend who shared the exile, stood beside Orestes at the killing, and never left through the madness and the flight. With it comes the recovery of Iphigenia. In Euripides’ Iphigenia among the Taurians, Apollo sends the still- haunted Orestes on a last errand: to fetch the wooden image of Artemis from the remote land of the Taurians on the Black Sea, where strangers are sacrificed to the goddess. The priestess who must consecrate the captured Greeks for death is Iphigenia herself — not slain at Aulis after all, but snatched from the altar by Artemis and carried here. Brother and sister recognize each other on the edge of the sacrifice, and the three escape with the image, Athena appearing to stay the Taurian king’s pursuit and to direct that the statue be installed in Attica. The sacrifice that began the whole catastrophe is undone; the daughter believed dead comes home alive; exile ends not in death but in return.

Texts and scholarship

The earliest portrait is Homer’s. In the Odyssey the avenger is invoked as a model son three times in the first four books, and the act is praised without qualification — the baseline against which the tragic complication is measured. For the tradition’s tangled genealogy and its variants across early epic, lyric, and tragedy, the standard reference handbook is Timothy Gantz, Early Greek Myth: A Guide to Literary and Artistic Sources (Johns Hopkins University Press, 1993), which collates the sources for the house of Atreus and the divergent versions of the revenge.

The central text is Aeschylus’s trilogy. The Eumenides — the trial play — is available in the public-domain prose of Herbert Weir Smyth’s Loeb edition (1926) through the Theoi Classical Texts Library, which presents the founding of the Areopagus, the prosecution by the Furies, Apollo’s defense, and Athena’s casting vote. Robert Fagles’s verse translation of the whole Oresteia (Penguin, 1979) remains the most widely read modern English rendering and is held under copyright. On the trial scene as a deliberate intervention in Athenian politics — Aeschylus’s founding of the homicide court read against the reforms of Ephialtes in 462/1 BCE — see the discussion in the Online Guide to Classical Mythology in the Arts (OGCMA), which sets the Eumenides of 458 BCE in its turbulent civic moment.

The myth’s later shape is best traced through the ancient reference tradition. The nineteenth-century compendium that still anchors English-language study of the figure is the entry on Orestes in William Smith’s Dictionary of Greek and Roman Biography and Mythology, hosted in the public domain at the Perseus Digital Library, which assembles the parentage, the rescue and upbringing in Phocis, the revenge, the pursuit, the Areopagus, and the Taurian journey from the scattered ancient authorities. The divergent dramatic treatments — Sophocles’ and Euripides’ Electra plays, Euripides’ Orestes, and the Iphigenia among the Taurians — are the primary evidence that the myth functioned as an arena for argument rather than a fixed report.

What the tradition kept returning to was the moment after the necessary crime — the question of how a person, or a city, stops the cycle without simply beginning it again.
