911 Agamemnon

911 Agamemnon is a large 167 kilometres (104 mi) trojan asteroid that orbits the Sun at the same distance as the planet Jupiter. It is located in the leading Lagrangian point L4. Based on IRAS data, Agamemnon is 167 kilometres (104 mi) in diameter and is probably the 2nd largest Jupiter Trojan. Recent observations of the asteroid's occultations characterize its shape and are suggestive of Agamemnon to have a satellite.

It was discovered by Karl Wilhelm Reinmuth on March 19, 1919, in Heidelberg, Germany. It is named after King Agamemnon, a main character of the Iliad.

Photometric observations of this asteroid during 1997 were used to build a light curve showing a rotation period of 6.5819 ± 0.0007 hours with a brightness variation of 0.29 ± 0.01 magnitude. A 2009 study yielded a period of 6.592 ± 0.004, in reasonable agreement with the previous result.

    In Greek mythology, Agamemnon (/æɡəˈmɛmnɒn/; Greek: Ἀγαμέμνων from *Ἀγαμέδμων [from ἄγαν, "very much" and μέδομαι, "think on"], "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 Iphigenia, Electra or Laodike (Λαοδίκη), Orestes and Chrysothemis. Mythical legends make him the king of Mycenae or Argos, thought to be different names for the same area. When Helen, the wife of Menelaus, ran off with Paris of Troy, Agamemnon commanded the united Greek armed forces in the ensuing Trojan War.

    Upon Agamemnon's return from Troy, he was murdered (according to the oldest surviving account, Odyssey 11.409–11) by Aegisthus, the lover of his wife, Clytemnestra. In old versions of the story, the scene of the murder, when it is specified, is usually the house of Aegisthus, who has not taken up residence in Agamemnon's palace, and it involves an ambush and the deaths of Agamemnon's followers as well. In some later versions Clytemnestra herself does the killing, or they do it together, in his own home.

    Oresteia

    The Oresteia (Ancient Greek: Ὀρέστεια) is a trilogy of Greek tragedies written by Aeschylus concerning the end of the curse on the House of Atreus. The name derives from the character Orestes, who sets out to avenge his father's murder.

    The only extant example of an ancient Greek theater trilogy, the Oresteia won first prize at the Dionysia festival in 458 BC. When originally performed, it was accompanied by Proteus, a satyr play that would have followed the trilogy. Proteus has not survived, however. In all likelihood the term "Oresteia" originally referred to all four plays; today it generally designates only the surviving trilogy.

    Many consider the Oresteia to be Aeschylus' finest work. Principal themes of the trilogy include the contrast between revenge and justice, as well as the transition from personal vendetta to organized litigation.

    Agamemnon

    Introduction

    The play Agamemnon (Ἀγαμέμνων, Agamemnōn) details the homecoming of Agamemnon, King of Argos, from the Trojan War. Waiting at home for him is his wife, Clytemnestra, who has been planning his murder, partly as revenge for the sacrifice of their daughter, Iphigenia, and partly because in the ten years of Agamemnon's absence Clytemnestra has entered into an adulterous relationship with Aegisthus, Agamemnon's cousin and the sole survivor of a dispossessed branch of the family (Agamemnon's father, Atreus, killed and fed Aegisthus's brothers to Aegisthus's father, Thyestes, when he took power from him), who is determined to regain the throne he believes should rightfully belong to him.

    Agamemnon (Zeus)

    Agamemnon or Zeus Agamemnon (Gr. Ἀγαμέμνων) was a cultic epithet of the Greek god Zeus, under which he was worshiped at Sparta. Some writers, such as Eustathius, thought that the god derived this name from the resemblance between him and the Greek hero Agamemnon; others that Zeus Agamemnon was merely a synecdoche glorifying the hero, not the god. Still others believed it to be a mere epithet signifying the eternal, from agan (ἀγὰν) and menon (μένων).
