Clytemnestra (; , Klytaimnḗstrā, ), in Greek mythology, was the wife of Agamemnon, king of Mycenae, and the twin sister of Helen of Troy. In Aeschylus' Oresteia, she murders Agamemnon – said by Euripides to be her second husband – and the Trojan princess Cassandra, whom Agamemnon had taken as a war prize following the sack of Troy; however, in Homer's Odyssey, her role in Agamemnon's death is unclear and her character is significantly more subdued. Name Her Greek name Klytaimnḗstra is also sometimes Latinized as Clytaemnestra. 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 (, "woo, court"). The original name form is believed to have been Klytaimḗstra () without the -n-. The present form of the name does not appear before the middle Byzantine period. Homeric poetry shows an awareness of both etymologies. Aeschylus, in certain wordplays on her name, appears to assume an etymological link with the verb mḗdomai (, "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". Background Clytemnestra was the daughter of Tyndareus and Leda, the King and Queen of Sparta, making her a Spartan Princess. According to the myth, Zeus appeared to Leda in the form of a swan, seducing and impregnating her. Leda produced four offspring from two eggs: Castor and Clytemnestra from one egg, and Helen and Polydeuces (Pollux) from the other. Therefore, Castor and Clytemnestra were fathered by Tyndareus, whereas Helen and Polydeuces were fathered by Zeus. Her other sisters were Philonoe, Phoebe and Timandra. Agamemnon and his brother Menelaus were in exile at the home of Tyndareus; in due time Agamemnon married Clytemnestra and Menelaus married Helen. In a late variation, Euripides's Iphigenia at Aulis, Clytemnestra's first husband was Tantalus, King of Pisa; Agamemnon killed him and Clytemnestra's infant son, then made Clytemnestra his wife. In another version, her first husband was King of Lydia. Mythology After Helen was taken from Sparta to Troy, her husband, Menelaus, asked his brother Agamemnon for help. Greek forces gathered at Aulis. However, consistently weak winds prevented the fleet from sailing on the ocean. Through a subplot involving the gods and omens, the priest Calchas said the winds would be favorable if Agamemnon sacrificed his daughter Iphigenia to the
