The Tempest

The magician Prospero, rightful Duke of Milan, and his daughter, Miranda, 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 then three-year-old Miranda. Possessing magic powers due to his great learning, Prospero is reluctantly served by a spirit, Ariel, whom Prospero had rescued from a tree in which he had been trapped by the witch Sycorax. Her son, Caliban, a deformed monster and the only non-spiritual inhabitant before the arrival of Prospero, was initially adopted and raised by him. 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 magician's slave. In slavery, Caliban has come to view Prospero as a usurper and has grown to resent him and his daughter.

The play opens as Prospero, having divined that his brother, Antonio, is on a ship passing close by the island, has raised a tempest which causes the ship to run aground. Also on the ship are Antonio's friend and fellow conspirator, King Alonso of Naples, Alonso's brother and son (Sebastian and Ferdinand), and Alonso's advisor, Gonzalo. All these passengers are returning from the wedding of Alonso's daughter Claribel with the King of Tunis. Prospero contrives to separate the shipwreck survivors into several groups by his spells, and so Alonso and Ferdinand are separated believing the other to be dead.
