In Aeschylus ' Oresteia trilogy, Clytemnestra kills her husband, King Agamemnon because he had sacrificed their daughter Iphigenia to proceed forward with the Trojan war, and Cassandra, a prophetess of Apollo.

In Greek mythology, Agamemnon (; Ancient Greek: ; modern Greek:, " very steadfast ") was the son of King Atreus and Queen Aerope of Mycenae, the brother of Menelaus, the husband of Clytemnestra, and the father of Electra and Orestes.

When Agamemnon came home he was slain by either Aegisthus ( in the oldest versions of the story ) or Clytemnestra.

Aegisthus and Thyestes thereafter ruled over Mycenae jointly, exiling Atreus ' sons, Agamemnon and Menelaus to Sparta, where King Tyndareus gave the pair his daughters, Clytemnestra and Helen, to take as wives.

While Agamemnon, the son of Atreus, was absent on his expedition against Troy, Aegisthus seduced Clytemnestra, the wife of Agamemnon, and was so wicked as to offer up thanks to the gods for the success with which his criminal exertions were crowned.

Unbeknownst to Agamemnon, while he was away at war, his wife, Clytemnestra, had begun an affair with Aegisthus.

Agamemnon initially rejects the hubris of walking on the fine purple tapestry, an act suggested by Clytemnestra, in hopes of bringing his ruin.

It also suggests that this event leads to the murder of Agamemnon by Clytemnestra ( the latter being the daughter of Leda ).

Incidentally, Telemachus learns the fate of Menelaus ’ brother Agamemnon, king of Mycenae and leader of the Greeks at Troy: he was murdered on his return home by his wife Clytemnestra and her lover Aegisthus.

His wife Clytemnestra ( Helen's sister ) was having an affair with Aegisthus, son of Thyestes, Agamemnon's cousin who had conquered Argos before Agamemnon himself retook it.

Possibly out of vengeance for the death of Iphigenia, Clytemnestra plotted with her lover to kill Agamemnon.

Tyndareus had two ill-starred daughters, Helen and Clytemnestra, whom Menelaus and Agamemnon married, respectively.

After the war, Agamemnon, returning, was greeted royally with a red carpet rolled out for him and then was slain in his bathtub by Clytemnestra, who hated him bitterly for having ordered the sacrifice of their daughter Iphigenia ( although the life of the latter had been saved ).

Clytemnestra was aided in her crime by Aegistheus, who reigned subsequently, but Orestes, son of Agamemnon, was smuggled out to Phocis.

He was slain by Agamemnon, King of Mycenae, who made Clytemnestra his wife.

In most sources, Iphigeneia is the daughter of Agamemnon and Clytemnestra, but Duris of Samos and other writers followed Stesichorus ' account.

Clytemnestra ( unsuccessfully ) warns Agamemnon that sacrificing Iphigenia for Helen's sake is, " buying what we most detest with what we hold most dear ".

Agamemnon initially rejects the hubris of walking on the fine purple tapestry, an act which is suggested by Clytemnestra, in hopes of bringing his ruin.

In Greek mythology, Orestes (; ) was the son of Clytemnestra and Agamemnon.

Orestes was absent from Mycenae when his father, Agamemnon, returned from the Trojan War with the Trojan princess Cassandra as his concubine, and thus not present for Agamemnon's murder by his wife, Clytemnestra, in retribution for his sacrifice of their daughter Iphigenia to obtain favorable winds during the Greek voyage to Troy.

In The Greek Myths the mythographer and poet, Robert Graves, translates and interprets the legends and myth fragments about Clytemnestra, Agamemnon, and Orestes, as suggesting a ritual killing of a " king " ( Agamemnon ) in very early religious ceremonies that were suppressed when patriarchy replaced the matriarchies of very ancient Greece.

The story of Orestes was the subject of the Oresteia of Aeschylus ( Agamemnon, Choephori, Eumenides ), of the Electra of Sophocles, and of the Electra, Iphigeneia in Tauris, Iphigenia at Aulis ( in which he appears as an infant carried by Clytemnestra ), and Orestes, of Euripides.

On the eve of sailing from Aulis he attempted to offer a sacrifice, as Agamemnon had done before the Trojan expedition, but the Thebans intervened to prevent it, an insult for which he never forgave them.

In order not to be surprised by the return of Agamemnon, he sent out spies, and when Agamemnon came, Aegisthus invited him to a repast at which he had him treacherously murdered.

The letter and gold were " discovered ", and Agamemnon had Palamedes stoned to death for treason.

According to Apollodorus, Agamemnon brought the Wine Growers, daughters of Anius, son of Apollo, who had the gift of producing by touch wine, wheat, and oil from the earth, in order to relieve the supply problem of the army.

Enraged at the dishonour Agamemnon had inflicted upon him, Achilles decided he would no longer fight.

Agamemnon, unwilling to undertake the invidious duty of deciding between the two competitors, referred the dispute to the decision of the Trojan prisoners, inquiring of them which of the two heroes had done most harm to the Trojans.

He had a feud with Orestes ( son of Agamemnon ) over Menelaus ' daughter Hermione, and was killed in Delphi, where he was buried.

In legend, Atreus had two sons, Agamemnon and Menelaus, the Atreids.

But neither the Atreus nor the Agamemnon of legend have any brothers named * Etewoclewes ( Eteocles ); this name, rather, is associated with Thebes, which during the preceding LHIIIA period Amenhotep III had viewed as equal to Mycenae.

Dio Chrysostom gives a completely different account of the story, questioning Homer's credibility: after Agamemnon had married Helen's sister, Klytaemnestra, Tyndareus sought Helen's hand for Menelaus on account of political reasons.

" Not all poets took Iphigenia and Iphianassa to be two names for the same heroine ," Kerenyi remarks, " though it is certain that to begin with they served indifferently to address the same divine being, who had not belonged from all time to the family of Agamemnon.

Clytemnestra had held a grudge against her husband Agamemnon for murdering their eldest daughter, Iphigenia, as sacrifice to Artemis or Athena ( disputed ).
