Agamemnon and Aegisthus (murderer and victim)

The relationship between Agamemnon, the supreme commander of the Achaean forces at Troy, and Aegisthus, the son of Thyestes who seduced Agamemnon's wife and murdered him upon his return, is one of the poem's most important structural parallels. It is introduced in the very first divine council, where Zeus uses Aegisthus's fate to illustrate the theme that mortals bring suffering upon themselves through their own folly, and it recurs throughout the epic as a warning to Odysseus, Telemachus, and the audience about the dangers awaiting a returning hero and the necessity of a son's vengeance.

Origins of the Enmity

While Agamemnon was fighting at Troy, Aegisthus remained safely in Argos and began an adulterous affair with Clytemnestra, Agamemnon's wife. At first, Clytemnestra resisted his advances, for she was of a good natural disposition, and Agamemnon had left a bard to guard her. But Aegisthus carried the bard off to a desert island and left him for birds to devour, after which Clytemnestra went willingly to his house. Aegisthus then offered many burnt sacrifices to the gods and decorated temples, having succeeded far beyond his expectations. Zeus, however, sent Hermes to warn Aegisthus not to kill Agamemnon nor to woo his wife, for Orestes would avenge his father when he came of age. Despite this divine warning, Aegisthus persisted, and Zeus declares that he has now paid one price for all.

The Murder of Agamemnon

When Agamemnon finally returned from Troy, Aegisthus laid an elaborate trap. He posted a watchman for a full year, promising him two talents of gold to ensure Agamemnon did not slip past. When the watchman saw Agamemnon approach, Aegisthus picked twenty of his bravest warriors and placed them in ambush on one side of the cloister while preparing a banquet on the opposite side. He then sent chariots to invite Agamemnon to the feast, unsuspecting of the doom awaiting him. At the banquet, Aegisthus killed Agamemnon as though butchering an ox in the shambles, and all of Agamemnon's followers were slain as well. The ghost of Agamemnon later describes the scene to Odysseus in the Underworld: the mixing bowl and loaded tables lay about, the ground reeked with blood, and he heard Priam's daughter Cassandra scream as Clytemnestra killed her beside him. As he lay dying with the sword in his body, he raised his hands to kill his murderess, but she slipped away and would not even close his eyes or mouth.

The Parallel to Odysseus's Story

The Agamemnon-Aegisthus relationship functions as a dark mirror for Odysseus's own situation. Nestor explicitly tells Telemachus that it is a good thing for a man to leave a son behind to do as Orestes did, urging Telemachus to show his mettle and make a name for himself. Agamemnon's ghost warns Odysseus not to be too friendly even with his own wife, to tell her only part of his plans, and to steal a march upon his enemies rather than announce his arrival. The parallel underscores the stakes of Odysseus's return: like Agamemnon, he faces a house overrun by suitors who are consuming his property and courting his wife; unlike Agamemnon, he has a faithful wife and a son who will stand with him. The contrast between Clytemnestra's treachery and Penelope's fidelity is repeatedly emphasized, most powerfully by Agamemnon's ghost, who declares Penelope a very admirable woman with an excellent nature.

Aegisthus's Downfall and Orestes's Vengeance

Aegisthus ruled in Mycenae for seven years after killing Agamemnon, with the people obedient under him. But in the eighth year, Orestes returned from Athens and killed the murderer of his father, then celebrated the funeral rites of his mother and Aegisthus with a banquet for the people of Argos. This act of filial vengeance is held up throughout the poem as the model for Telemachus to emulate. Zeus himself uses Aegisthus's fate to demonstrate that divine justice operates through human agents: though Aegisthus was warned, he ignored the warning and paid the full price. The story thus establishes the moral framework within which Odysseus's own revenge against the suitors will be understood.

Narrative and Thematic Significance

The Agamemnon-Aegisthus relationship is not merely a backstory but a structural and thematic linchpin of the Odyssey. It is the first example Zeus gives of human folly bringing about its own punishment, it provides the template for Telemachus's maturation into an avenger, and it offers a cautionary counterpoint to Odysseus's own homecoming. The contrast between the two households—one destroyed by adultery and murder, the other preserved by fidelity and cunning—reinforces the poem's central values of loyalty, hospitality, and the restoration of rightful order. Agamemnon's ghost, even in death, serves as a witness to the consequences of betrayal and a voice affirming the justice of Odysseus's impending slaughter of the suitors.
