The document discusses the master-slave relationship between Prospero and Caliban in Shakespeare's play The Tempest. Prospero gains power over the island and its original inhabitant Caliban, who loses his power and freedom. Their relationship is complex, as Prospero justifies his enslavement of Caliban by claiming Caliban tried to rape his daughter. Meanwhile, Ariel is also Prospero's slave but is submissive due to the promise of eventual freedom, unlike the rebellious Caliban who has no such promise. Both Ariel and Caliban are subject to Prospero's magical powers and commands, though their attitudes towards their servitude differ.
