Cassandra, 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 Greek mythology, the daughter of King Priam of Troy. Apollo promised her the gift of prophecy if she would grant his desires; she accepted the gift but rebuffed the god, who took his revenge by ordaining that her prophecies should never be believed. She predicted the fall of Troy and the death of Agamemnon, but her warnings went unheeded. Given as part of the war spoils to Agamemnon, she was murdered with him.
