In Greek mythology, Cassandra (also known as Alexandra) was the daughter of king Priam and Queen Hecuba of Troy. According to Homer she was the most beautiful of the daughters of Priam. Her beauty caused Apollo to grant her the gift of prophecy. In an alternative version - she spent a night at Apollo's temple, at which time the temple snakes licked her ears clean so that she was able to hear the future. This is a recurring theme in Greek mythology, though sometimes it brings an ability to understand the language of animals rather than an ability to know the future. However, when she did not return his love, Apollo placed a curse on her so that no one would ever believe her predictions.
The names Alexandra & Cassandra are recorded in the Mycenaean texts (the monument of the ancient Greek dialect writing (16th to 12th centuries BC)
