Agamemnon, by Aeschylus

<p>Cassandra knew through a prophetic vision that a sword would pierce her heart. Agamemnon, her captor, took her to his home where an avenging wife, Clytemnestra, awaited. The tragedies of the doom that requited the sins of the House of Atreus are among the most powerful ever written. (Volume 8, Harvard Classics)</p>
