Consider if you will: The Tempest.....
Parallel stories. Parallel characters. You have entered Shakespeare's Twilight Zone.
In The Tempest, certain themes are repeated between many different characters and situations. A theme that reoccurs throughout the play is that of taking people's power away from them. Examples:
*Prospero is usurped by Antonio
*Caliban is usurped by Prospero
*The Cook attempts to usurp Prospero
By repeating this theme, Shakespeare reinforces lessons about dishonesty and personal freedom.
Caliban and Ariel are parallel characters. They differ in many ways, but at the same time they remain similar.
*Caliban and Ariel are both enslaved to masters
*Caliban and Ariel both want to be free
*Both characters are extreme examples are ways of being: Caliban as evil and Ariel as good.
*Caliban and Ariel both have perceptions about the natural reality of the island and the magic that is taking place
*Both are freed by the end of the play
*Caliban wants to make people miserable because he is. Ariel doesn't want to harm anyone.
*Caliban is imprisoned by his appearance. Ariel is not physically imprisoned.
