Cassandra, pictured here in a sculpture by Max Klinger, was a legendary Greek seer, whose great gift became a curse. She was said to be endowed with prophecy by the god Apollo, in exchange for her love. But when she didn't return his affections, he punished her by making everyone who heard her accurate forecasts believe they were instead being told lies. Most notably, no one listened to her warning about not accepting the wooden horse at Troy.
