Clytemnestra

Her Greek name Klytaimnḗstra is also sometimes Latinized as Clytaemnestra.^[5] It is commonly glossed as "famed for her suitors." However, this form is a later misreading motivated by an erroneous etymological connection to the verb mnáomai (μνάoμαι, "woo, court"). The original form is believed to have been Klytaimḗstra (Κλυταιμήστρα) without the -n-. The present form of the name does not appear before the middle Byzantine period.^[6] Homeric poetry shows an awareness of both etymologies.^[7]

Aeschylus, in certain wordplays on her name, appears to assume an etymological link with the verb mḗdomai (μήδoμαι, "scheme, contrive"). Thus given the derivation from κλῠτός (klutós "celebrated") and μήδομαι (mḗdomai "to plan, be cunning"), this would result in the quite descriptive "famous plotter".^[8]

Clytemnestra was one of the children born to Tyndareus and Leda, king and queen of Sparta; her full siblings included Castor, Philonoe, Phoebe and Timandra.^[9] Her mother Leda also slept with Zeus (in the guise of a swan), producing Clytemnestra's half-siblings Pollux and Helen, and sometimes Castor too, though in many versions Helen's birth is separate from that of the Dioscuri.^[10][11] Additionally, sometimes Helen is a daughter of Zeus by the goddess Nemesis, making her the adoptive sister of Tyndareus and Leda's children.^[11][12]

Although referring to Clytemnestra and Helen as twins (born to different fathers) is common in modern interpretations, ancient sources do not support this; the first author to mention a single event of shared egg birth of all four (Clytemnestra, Helen and the Dioscuri) was the First Vatican Mythographer followed by the Third Vatican Mythographer,^[b][15] and the origin of the sisters as twins is unclear.^[16][14] The duality of the Dioscuri, who are twins in multiple sources, seems to have been contagious and spread over to various figures around them, including their sisters.^[16] Pairing Clytemnestra with Helen might have been for the purpose of strengthening her association with Sparta.^[17]

Clytemnestra is most commonly described as having two husbands: Agamemnon and Aegisthus. Some sources name a third, Tantalus, whom Agamemnon slays before taking Clytemnestra as his wife.^[18][19] The child Clytemnestra has with her first husband is killed too.^[19] Another myth says both Agamemnon and his brother Menelaus, King of Sparta, compete as suitors for Clytemnestra and Helen's hands, with Agamemnon marrying Clytemnestra and Menelaus marrying Helen.^[20] Clytemnestra becomes queen of Mycenae through the marriage and bears Agamemnon four children: Orestes, Electra, Iphigenia, and Chrysothemis. Some time after Agamemnon leaves for Troy, Clytemnestra begins an affair with Aegisthus, son of Thyestes and her husband's cousin.^[21] After murdering Agamemnon, they rule Mycenae as king and queen consort.^[22] They have a son, Aletes, and two daughters, Erigone and Helen.^[23][24]

According to Stesichorus, Tyndareus forgets to honor Aphrodite while sacrificing to the gods. Angry at Tyndareus for excluding her, the goddess curses his daughters to be adulterous wives.^[25]

After Helen is taken by Paris to Troy, her husband, Menelaus, asks all Helen's suitors, including Agamemnon, to help retrieve her.^[26][27] Greek forces gather at the port city of Aulis, but consistently weak winds prevent the fleet from sailing to Troy. The priest Calchas prophesies that the winds will be favorable if Agamemnon sacrifices his daughter Iphigenia to the goddess Artemis to atone for killing her sacred deer.^[28] Agamemnon persuades Clytemnestra to send Iphigenia to him, telling her he is going to marry her to the hero Achilles.^[29][30] When Iphigenia arrives at Aulis, she is sacrificed, the winds turn, and the troops set sail for Troy.

The Trojan War lasts ten years. During this period of Agamemnon's long absence, Clytemnestra begins a love affair with Aegisthus, her husband's cousin and the son of Thyestes.^[31] Whether Clytemnestra is seduced into the affair^[32] or enters into it independently^[33] differs among authors and versions of the myth. Together, the pair begins plotting Agamemnon's demise. Depending on the version of the myth, different reasons have been given for Clytemnestra's decision to murder her husband. These include being angered by the sacrifice of Iphigenia,^[30][34] being seduced into the idea by Aegisthus so that he could take the throne and avenge his father,^[35] and being insulted by Agamemnon taking Cassandra as a concubine and giving her preferential treatment.^[c]

Murder of Agamemnon

After defeating the Trojans, Agamemnon returns to Mycenae. He brings with him a war prize: Cassandra, a seer cursed by Apollo so that her prophecies will never be believed.^[39] Upon his return, Agamemnon is murdered either by Aegisthus, Clytemnestra, or the two acting together. The character who strikes the killing blow and Clytemnestra's characterization differ between authors and versions of the myth.

In Aeschylus' play Agamemnon, one of the better-known versions of the story, Clytemnestra is portrayed as a conniving, bloodthirsty woman whose desires are encouraged by Aegisthus, wanting to avenge his father.^[40] In the play, Clytemnestra welcomes her husband home and helps him down from his chariot before escorting him into the palace. Cassandra remains outside in the chariot, where she receives a premonition and prophesies that Clytemnestra will murder Agamemnon; a crowd watches and listens, but is unable to comprehend what she says.^[41] In this version of the story, Clytemnestra waits until Agamemnon is in his bath before she entangles him in a net and stabs him three times.^[42] Cassandra, accepting her fate, walks into the palace and is killed as well. When Clytemnestra's act is discovered by the crowd, she revels in the deed and defends her actions, announcing that she has finally avenged Iphigenia's murder.^[43]

In Euripides' Electra, Electra claims that, while her mother was involved in the plot, Aegisthus was the one who struck the killing blow.^[22] Alternately, Homer has the pair acting together. In the Odyssey, Agamemnon's shade claims that Aegisthus and Clytemnestra hosted a feast, during which the pair launched a surprise attack and murdered him alongside a number of his soldiers. In this version, Clytemnestra killed Cassandra alone.^[44]

Clytemnestra appears in numerous works from ancient to modern times, sometimes as a villain and sometimes as a sympathetic antihero.^[50][51] Author and classicist Madeline Miller wrote "[a]fter Medea, Queen Clytemnestra is probably the most notorious woman in Greek mythology".^[52]

• Clytemnestra is one of the main characters in Aeschylus's Oresteia, and is central to the plot of all three parts. She murders Agamemnon in the first play, and is murdered herself in the second. Her death then leads to the trial of Orestes by a jury composed of Athena and 12 Athenians in the final play. Her role is the largest in any surviving Greek tragedy.^[53]
