What information should i know for a test on Julius Caesar?

Acknowledge the attention paid (or not paid) to omens, nightmares, and other supernatural events. Note how the various responses to these phenomena illustrate the struggle between fate and free will. Consider whether the play’s tragedies can be attributed to the characters’ failure to read the omens properly, or if the omens merely for tell the inevitable. Also, think about Caesar the mortal man as opposed to Caesar the public figure. Note Caesar's power,and how he continues to wield power over events even after he is dead.
