The sorcerer Prospero,(BEN) rightful Duke of Milan, and his daughter, Miranda,(ALEX) have been stranded for twelve years on an island, after Prospero's jealous brother Antonio—helped by Alonso, the King of Naples—deposed him and set him adrift with the three-year-old Miranda. Prospero secretly sought the help of Gonzalo(?) and their small and shoddy boat had secretly been upgraded to be more than sea worthy, it had been supplied with plenty of food and water, it had an excellent library (BENS LIBRARY) and contained surviving material in case the boat capsized. Possessed of magic powers due to his great learning and prodigious library, Prospero is reluctantly served by a spirit,(SMOKEY) Ariel whom he had rescued from imprisonment in a tree. Ariel was trapped therein by the African witch Sycorax,(JACOB) who had been exiled to the island years before and died prior to Prospero's arrival; Prospero maintains Ariel's loyalty by repeatedly promising to release the "airy spirit" from servitude, but continually defers that promise to a future date, namely at the end of the play. The witch's son Caliban,(RICHARD?) a deformed monster and the only non-spiritual inhabitant before the arrival of Prospero, was initially adopted and raised by the Milanese sorcerer. He taught Prospero how to survive on the island, while Prospero and Miranda taught Caliban religion and their own language. Following Caliban's attempted rape of Miranda, he had been compelled by Prospero to serve as the sorcerer's slave, carrying wood and gathering pig nuts. In slavery Caliban has come to view Prospero as a usurper, and grown to resent the magician and his daughter, feeling that they have betrayed his trust. Prospero and Miranda in turn view Caliban with contempt and disgust.
