The Unheeded Warnings
Cassandra foresaw the fall of Troy and specifically warned against bringing the wooden horse inside the city walls, but was dismissed as a madwoman. After Troy's fall she was taken as a captive concubine by Agamemnon and was murdered alongside him upon their return to Mycenae by Clytemnestra.
As with all figures of Greek heroic legend, sources diverge on many particulars; the account above follows the most widely transmitted classical tradition.
