Mortal daughter of Agamemnon and Clytemnestra; the first-named of the three daughters Agamemnon offers Achilles in Iliad 9. In Sophocles's Electra she is the prudent, submissive sister — the dramatic foil to Electra, declining to join the vengeance she fears. Sister of Iphigenia, Electra, and Orestes. Authored mortal: a scion father and mortal mother.
