Agamemnon  (ag-ȧ-mem ´non).—The greatest of the tragedies of Æschylus. The scene is laid in Argos, in the palace of Agamemnon, at the time of the king's return from the capture of Troy; the catastrophe is the murder (behind the scenes) of Agamemnon and Cassandra (whom he has brought captive with him) by the queen Clytemnestra, urged on by her paramour Ægisthus.
Agamemnon  (ag-a-mem ´nōn ).—King of Mycenæ, and brother of Menelaus. He married Clytemnestra, who bore him Iphigenia, Chrysothemis, Laodice (Electra) and Orestes. He was the most powerful prince in Greece. When Helen (q.v.) was carried off by Paris, and the Greek chiefs sought to regain her, Agamemnon was chosen commander-in-chief of the expedition. He is not, however, the hero of the Iliad, as he is the inferior of Achilles in true nobility of character. At the capture of Troy he received Cassandra, the daughter of Priam, as his prize. On his return home he was murdered by Ægisthus, who, during his absence at Troy, had been living with Agamemnon's wife Clytemnestra. His son Orestes avenged his father's death by slaying both Ægisthus and Clytemnestra.
