In Greek mythology, Agamemnon (; Agamémnōn) was a king of Mycenae who commanded the Achaeans during the Trojan War. He was the son (or grandson) of King Atreus and Queen Aerope, the brother of Menelaus, the husband of Clytemnestra, and the father of Iphigenia, Iphianassa, Electra, Laodike, Orestes and Chrysothemis.Homer, Iliad 9.145. Legends make him the king of Mycenae or Argos, thought to be different names for the same area. Agamemnon was killed upon his return from Troy by Clytemnestra, or in an older version of the story, by Clytemnestra's lover Aegisthus.

Etymology Different etymologies have been proposed for the name Agamemnon (). According to one view, the name means 'very steadfast', 'unbowed' or 'resolute'. This is based on the interpretation of the name as a compound word comprising the elements 'very much' and 'to stay, wait; stand fast'. According to another view, the name developed from the unattested form * (*), a compound word composed of the elements 'very much' and 'to think on, provide for', with the overall meaning of 'very mindful'. Yet another proposal derives the second part of the compound word from 'to be inclined, to wish eagerly, to strive' for the overall meaning of 'very eagerly wishing'. Linguist Václav Blažek proposes a relationship with Vedic Sanskrit Agni on etymological and functional bases.

Ancestry and early life

Agamemnon was a descendant of Pelops, son of Tantalus.For a discussion of the house of Tantalus see Gantz, pp. 531556. For Agamemnon's genealogy see, Grimal, p. 526 Table 2, and p. 534 Table 13. According to the common story (as told in the Iliad and Odyssey of Homer), Agamemnon and his younger brother Menelaus were the sons of Atreus, king of Mycenae, and Aerope, daughter of the Cretan king Catreus.Grimal, s.v. Menelaus; Hard, pp. 355, 507, 508; Collard and Cropp 2008a, p. 517; Gantz, p. 552; Parada, s.v. Agamemnon; Euripides, Helen 390–392, Orestes 16; Hyginus, Fabulae 97; Apollodorus, E.3.12; Scholia on Iliad 1.7 (citing "Homer" = Hesiod Catalogue of Women fr. 137a Most) and Scholia on Tzetzes' Exegesis in Iliadem 1.122 (citing "Homer" = Hesiod Catalogue of Women fr. 137c Most). They are also the sons of Atreus, in the Iliad and Odyssey, see for example Iliad 11.131, Odyssey 4.462, although Aerope is not mentioned (see Gantz, p. 522). See also Euripides, Iphigenia in Tauris 45, (Atreus as father, no mention of mother); Hesiod Catalogue of Women fr. 138 Most [= fr. 195 MW], and Sophocles, Ajax 12951297 (Aerope as mother, no mention of father). However, according to another tradition, Agamemnon and Menelaus were the sons of Atreus' son Pleisthenes, with their mother being Aerope, Cleolla, or Eriphyle. In this tradition, Pleisthenes dies young, with Agamemnon and Menelaus being raised by Atreus.Hard, pp. 355, 508; Collard and Cropp 2008a, p. 517; Collard and Cropp 2008b, p. 79; Gantz, pp. 552553; Parada, s.v. Agamemnon. For Aerope as mother see: Apollodorus, 3.2.2; Dictys Cretensis, 1.1; Scholia on Iliad 1.7 (citing "Hesiod" = Hesiod Catalogue of Women fr. 137a Most) and Scholia on Tzetzes' Exegesis in Iliadem 1.122 (citing "Hesiod" = Hesiod Catalogue of Women fr. 137c Most). For Cleolla, see Tzetzes, Exegesis in Iliadem 1.122 (citing "Hesiod, Aeschylus, and some others" = Hesiod Catalogue of Women fr. 137b Most). For Eriphyle see Gantz, p. 553 (citing Scholia on Euripides Orestes 4). Agamemnon had a sister Anaxibia (or Astyoche) who married Strophius, the son of Crisus.Hard, p. 566; Gantz, p. 223; Parada, s.vv. Anaxibia 4, Astyoche 6. For Anaxibia as the sister's name see Pausanias, 2.29.4; Dictys Cretensis, 1.1; Tzetzes, Exegesis in Iliadem 1.122 (= Hesiod Catalogue of Women fr. 137b Most); Scholia on Tzetzes' Exegesis in Iliadem 1.122 (= Hesiod Catalogue of Women fr. 137c Most). For Astyoche, as the sister's name, see Hyginus, Fabulae 117.

Agamemnon's father, Atreus, murdered the sons of his twin brother Thyestes and fed them to Thyestes after discovering Thyestes' adultery with his wife Aerope. Thyestes fathered Aegisthus with his own daughter, Pelopia, and this son vowed gruesome revenge on Atreus' children. Aegisthus murdered Atreus, restored Thyestes to the throne, and took possession of the throne of Mycenae and jointly ruled with his father. During this period, Agamemnon and his brother Menelaus took refuge with Tyndareus, King of Sparta.

In Sparta, Agamemnon and Menelaus respectively married Tyndareus' daughters Clytemnestra and Helen. In some stories (such as Iphigenia at Aulis by Euripides) Clytemnestra was already married to Tantalus, another son of Thyestes, whom Agamemnon murders along with the couple's infant son before marrying Clytemnestra. Menelaus succeeded Tyndareus in Sparta, while Agamemnon, with his brother's assistance, drove out Aegisthus and Thyestes to recover his father's kingdom. He extended his dominion by conquest and became the most powerful prince in Greece.

The number of children Agamemnon and Clytemnestra had varies according to source. In the Iliad, Agamemnon states that he has three daughters: Chrysothemis, Laodike, and Iphianassa. In Aeschylus' Oresteia, he has one son, Orestes, and two daughters, Iphigenia and Electra; Sophocles' Electra adds a daughter named Chrysothemis. Some also make Halaesus, an enemy of Aeneas in Italy, an illegitimate son of Agamemnon.Servius on Virgil's Aeneid, 7.723

Agamemnon's family history had been tarnished by murder, incest, and treachery, consequences of the heinous crime perpetrated by his ancestor, Tantalus, and then of a curse placed upon Pelops, son of Tantalus, by Myrtilus, whom he had murdered. In Aeschylus' Oresteia, misfortune hounded successive generations of the House of Atreus, until atoned by Orestes in a court of justice held jointly by humans and gods.

Trojan War

Sailing for Troy

Agamemnon gathers the reluctant Greek forces to sail for Troy. In order to recruit Odysseus, who is feigning madness so as to not have to go to war, Agamemnon sends Palamedes, who threatens to kill Odysseus' infant son, Telemachus. Odysseus is forced to stop acting mad in order to save his son and joins the assembled Greek forces. Preparing to depart from Aulis, a port in Boeotia, Agamemnon's army incurs the wrath of the goddess Artemis, although the myths give various reasons for this. In Aeschylus' play Agamemnon, Artemis is angry for she predicts that so many young men will die at Troy, whereas in Sophocles' Electra, Agamemnon has slain an animal sacred to Artemis, and subsequently boasts that he is her equal in hunting. Misfortunes, including a plague and a lack of wind, prevent the army from sailing. Finally, the prophet Calchas announces that the wrath of the goddess can only be propitiated by the sacrifice of Agamemnon's daughter Iphigenia.

Classical dramatizations differ on how willing either father or daughter are to this fate; some include such trickery as claiming she was to be married to Achilles, but Agamemnon does eventually sacrifice Iphigenia. Her death appeases Artemis and the Greek army set out for Troy. Several alternatives to the human sacrifice have been presented in Greek mythology. Other sources, such as Iphigenia at Aulis, say that Agamemnon is prepared to kill his daughter but that Artemis accepts a deer in her place and whisks her away to Tauris in the Crimean Peninsula. However, this version is widely considered to be the work of an interpolator, and not Euripides himself.Richard Rutherford, in John Davie (tr.), Euripides: The Bacchae and Other Plays, London, Penguin Books, 2005, pp. 174, 326–327. Hesiod says she became the goddess Hecate.

During the war, but before the events of the Iliad, Odysseus contrives a plan to get revenge on Palamedes for threatening his son's life. By forging a letter from Priam, king of the Trojans, and caching some gold in Palamedes' tent, Odysseus has Palamedes accused of treason and Agamemnon orders him to be stoned to death.

The Iliad

The Iliad tells the story of the quarrel between Agamemnon and Achilles in the final year of the war. In Book One, following one of the Achaean army's raids, Chryseis, daughter of Chryses, one of Apollo's priests, is taken as a war prize by Agamemnon. Chryses pleads with Agamemnon to free his daughter but meets with little success. Chryses then prays to Apollo for the safe return of his daughter. Apollo responds by unleashing a plague over the Achaean army. The prophet Calchas tells that the plague may be dispelled by returning Chryseis to her father. After bitterly berating Calchas for his painful prophecies, which first forced him to sacrifice his daughter and now to return his concubine, Agamemnon reluctantly agrees. However, Agamemnon demands a new prize from the army as compensation and seizes Achilles' prize, the beautiful captive Briseis. This creates deadly resentment between Achilles and Agamemnon, causing Achilles to withdraw from battle and refuse to fight.

Agamemnon is then visited in a dream by Zeus who tells him to rally his forces and attack the Trojans (in Book Two). After several days of fighting, including duels between Menelaus and Paris, and between Ajax and Hector, the Achaeans are pushed back to the fortifications around their ships. In Book Nine, Agamemnon, having realized Achilles's importance in winning the war, sends ambassadors begging for Achilles to return, offering him riches and the hand of his daughter in marriage. Achilles refuses, only being spurred back into action when his companion Patroclus is killed in battle by Hector, eldest son of King Priam and Queen Hecuba. In Book Nineteen, Agamemnon, reconciled with Achilles, gives him the offered rewards for returning to the war. Achilles sets out to turn back the Trojans and to duel with Hector. After Hector's death, Agamemnon assists Achilles in performing Patroclus' funeral in Book Twenty-three. Agamemnon volunteers for the javelin throwing contest, one of the games being held in Patroclus' honor, but his skill with the javelin is so well known that Achilles awards him the prize without contest.

Although not the equal of Achilles in bravery, Agamemnon was a representative of "kingly authority". As commander-in-chief, he summoned the princes to the council and led the army in battle. His chief fault was his overwhelming haughtiness; an over-exalted opinion of his position that led him to insult Chryses and Achilles, thereby bringing great disaster upon the Greeks.

Agamemnon was the commander-in-chief of the Greeks during the Trojan War. During the fighting, Agamemnon killed Antiphus and fifteen other Trojan soldiers, according to one source.Hyginus, Fabulae 114 . In the Iliad itself, he is shown to slaughter hundreds more in Book Eleven during his aristeia, loosely translated to "day of glory", which is the most similar to Achilles' aristeia in Book Twenty-one. Even before his aristeia, Agamemnon is considered to be one of the three best warriors on the Greek side, as proven when Hector challenges any champion of the Greek side to fight him in Book Seven, and Agamemnon (along with Diomedes and Ajax the Greater) is one of the three Hector most wishes to fight out of the nine strongest Greek warriors who volunteer.
