Overview
Clytemnestra (, ; , Klytaimnḗstrā, ), in Greek mythology, was the wife of Agamemnon, king of Mycenae, and the half-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.
