Cassandra

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.
