The study of Greek mythology can provide examples of failure to heed the call of emergency management specialists and experts. The story of Cassandra is an illustration of this warning. To win her favor, the Greek god Apollo gave her power to predict the future. However, once she received the gift, she refused further advances, angering Apollo. In retaliation, he cursed her with an additional power of an inability to convince anyone the predictions were true. For emergency managers and other related agencies, Cassandra has come to represent the challenges faced when trying to convince others that predicted events will happen.
