Cassandra

Cassandra, in Greek mythology, a daughter of Priam and Hecuba, who had the gift of prophecy bestowed upon her by Apollo, who, however, with the generosity which often characterised the gods, neutralised his gift by accompanying it with the condition that she should never be believed. Thus, her prophecy of the downfall of Troy had no further effect than causing her to be looked on as "the wild Cassandra," as AEnone calls her in Tennyson's poem. At the sack of the city she was dragged from Athena's temple by Ajax Oileus, and finally fell to the share of Agamemnon, and was murdered by Clytemnestra.
