Cassandra(kəsăn`drə), in Greek legend, Trojan princess, daughter of Priam and Hecuba. She was given the power of prophecy by Apollo, but because she would not accept him as a lover, he changed her blessing to a curse, causing her prophecies never to be believed. While seeking refuge from the Greeks during the Trojan War, she was dragged from the temple of Athena and violated by the Locrian Ajax. After the war she was the slave of Agamemnon and was killed with him by his wife Clytemnestra. She was also known as Alexandra.
in ancient Greek mythology, the daughter of the Trojan king Priam and Hecuba.
Captivated by Cassandra’s beauty, the god Apollo endowed her with the gift of prophecy. But after she rejected him, Apollo decreed that no one would believe her prophecies. The Trojans, in particular, did not heed the words of Cassandra, who cautioned Paris against abducting Helen, an act that triggered the Trojan War. After the capture of Troy by the Greeks, Agamemnon took Cassandra captive; she died with him at the hands of his wife, Clytemnestra.
Figuratively, the term “Cassandra’s prophecies” means gloomy predictions that are mistrusted by listeners.
