cassandra in mythology
I thought this was interesting:
In Greek mythology, Cassandra was the daughter of King Priam and Queen Hecuba of Troy. Her beauty caused Apollo, God of Knowledge, to grant her the gift of prophecy. However, when she did not return his love, Apollo placed a curse on her so that no one would ever believe her predictions. The curse caused her gift to become a source of endless pain and frustration.
While Cassandra foresaw the destruction of Troy (she warned the Trojans about the Trojan Horse, the death of Agamemnon, and her own demise), she was unable to do anything to forestall these tragedies.
