There is no obvious single source for the plot of The Tempest, but researchers have seen parallels in Erasmus' Naufragium, Peter Martyr's De orbe novo, and eyewitness reports by William Strachey and Sylvester Jordain of the real-life shipwreck of the Sea Venture on the islands of Bermuda, and the subsequent conflict between Sir Thomas Gates and Sir George Somers. In addition, one of Gonzalo's speeches is derived from Montaigne's essay Of the Canibales, and much of Prospero's renunciative speech is taken word for word from a speech by Medea in Ovid's poem Metamorphoses. The masque in Act 4 may have been a later addition, possibly in honour of the wedding of Princess Elizabeth and Frederick V in 1613. The play was first published in the First Folio of 1623.
The story draws heavily on the tradition of the romance, and it was influenced by tragicomedy, the courtly masque and perhaps the commedia dell'arte. It differs from Shakespeare's other plays in its observation of a stricter, more organised neoclassical style. Critics see The Tempest as explicitly concerned with its own nature as a play, frequently drawing links between Prospero's "art" and theatrical illusion, and early critics saw Prospero as a representation of Shakespeare, and his renunciation of magic as signalling Shakespeare's farewell to the stage. The play portrays Prospero as a rational, and not an occultist, magician by providing a contrast to him in Sycorax: her magic is frequently described as destructive and terrible, where Prospero's is said to be wondrous and beautiful. Beginning in about 1950, with the publication of Psychology of Colonization by Octave Mannoni, The Tempest was viewed more and more through the lens of postcolonial theory—exemplified in adaptations like Aimé Césaire's Une Tempête set in Haiti—and there is even a scholarly journal on post-colonial criticism named after Caliban.
The Tempest did not attract a significant amount of attention before the ban on the performance of plays in 1642, and only attained popularity after the Restoration, and then only in adapted versions. In the mid-19th century, theatre productions began to reinstate the original Shakespearean text, and in the 20th century, critics and scholars undertook a significant re-appraisal of the play's value, to the extent that it is now considered to be one of Shakespeare's greatest works. It has been adapted numerous times in a variety of styles and formats: in music, at least 46 operas by composers; orchestral works by Tchaikovsky; and songs; in literature, Percy Bysshe Shelley's poem With a Guitar, To Jane; in paintings; and on screen, inclujding Julie Taymor's 2010 film version which changed Prospero to Prospera (as played by Helen Mirren), and Des McAnuff's 2010 Stratford Shakespeare Festival production which starred Christopher Plummer.
Synopsis:
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 (aided by Alonso, the King of Naples) deposed him and set him adrift with the 3-year-old Miranda. Gonzalo, Alonso's counselor, had secretly supplied their boat with some food, fresh water, "rich garments, linens, stuffs and necessaries", and "volumes" (books) that Prospero prizes. 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 cruel witch, Sycorax, after he had refused to obey her. Prospero maintains Ariel's loyalty by repeatedly promising to release the "airy spirit" from servitude. Sycorax had been exiled from Algiers to the island for wreaking havoc with her magic, and had died before Prospero's arrival and without releasing Ariel. Sycorax' 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. In slavery, Caliban has come to view Prospero as a usurper and has grown to resent him and his daughter. Prospero and Miranda in turn view Caliban with disappointment, contempt and disgust. Prospero only performs one act of magic himself directly on stage: he disarms Ferdinand, causing his nerves to become "in their infancy again". The rest of his magic is through controlling spirits (or mentioned as happening previously), which is how magicians of the time were believed to operate.
Prospero, having divined that his brother Antonio is on a nearby ship, has raised a tempest that causes the passengers to believe they are shipwrecked and marooned. Also on the ship are Antonio's friend and fellow conspirator, King Alonso of Naples, Alonso's brother and son (Sebastian and Ferdinand, respectively) and Alonso's "trusted counselor", Gonzalo. All these passengers are returning from the wedding of Alonso's daughter Claribel and the King of Tunis. Prospero contrives to separate the shipwreck survivors into several groups by his spells, and so Alonso and Ferdinand are separated, each believing the other to be dead.
Prospero then explains that he tested Ferdinand, and betroths a willing Miranda to him. He then asks Ariel to bring some other spirits and create a masque to entertain the young couple. These spirits present a blessing by Iris, Ceres, and Juno, followed by dancing. Prospero suddenly remembers the plot against his life, dismisses the spirits and Miranda and Ferdinand, and sets a trap for Caliban, Trinculo, and Stephano. They are chased offstage by goblins in the shape of hounds.
Prospero, all his enemies in his power, discovers that Ariel would pity them if he were "human", and decides to forgive the people who tried to kill him. He tells Ariel to fetch the nobles while he breaks his charms.
In the conclusion, all the main characters are brought together before Prospero, who forgives Alonso, Antonio and Sebastian. Ariel is charged to prepare the proper sailing weather to guide the King's ship back to the Royal fleet and then to Naples, where Ferdinand and Miranda will be married. After discharging this task, Ariel will finally be free. Prospero pardons Caliban, who is sent to prepare Prospero's cell, to which Alonso and his party are invited for a final night before their departure. (It is however not made clear whether, after their departure, Caliban will remain on the island or whether he will be taken to Naples). Prospero indicates that he intends to entertain them with the story of his life on the island. Prospero has resolved to break and bury his magic staff, and "drown" his book of magic, and in his epilogue, shorn of his magic powers, he invites the audience to set him free from the island with their applause.
