Cassandra is a woman featuring in Greek mythology, who is blessed by Apollo the gift of foretelling. However, when she does not return his love he curses her to be never believed by others. This causes her the eternal suffering of seeing the future yet being completely helpless as no one will believe her clairvoyance.
This theme has been portrayed in many works, such as Twelve Monkeys where it is shown how someone who knows the future will most likely be treated as a lunatic in society. Because society has a tendency to treat anyone different to the norm as “abnormal” and therefore inferior, it is easy for a society to reject such a gift.
