The storm (i.e. tempest) in question takes place off a remote, desolate, and magical island upon which lives the usurped and exiled Duke of Milan, Prospero, and his daughter, Miranda. The reader realizes that the storm’s timing is too great a coincidence when it’s revealed that among those on a ship caught in the tempest is Antonio, the usurping Duke of Milan. The learned Prospero has developed some magic abilities and gained control over some of the island’s airy spirits — most notably Ariel — as well as the deformed monster / slave named Caliban. Caliban was the son of a witch who was previously in charge of the island, Sycorax. Under Sycorax’s rule, Ariel and the other spirits were imprisoned, so Ariel and the others are now in indentured servitude to Prospero.
The brilliant mind of Prospero has hatched a plot that isn’t all vengeance, but also intends to get his daughter a worthy husband in the form of Ferdinand, the son of the King of Naples. Both father (Alonso) and son (Ferdinand) are washed ashore after the apparent capsize of the ship, but Prospero sees to it that they are separated. The separation not only allows Ferdinand and Miranda to get acquainted, but also allows Alonso to be put through some trials to hasten his willingness to agree to the intended marriage. As Prospero is using Ariel to carry out his plot, under promise that he will free her, Caliban has joined with some drunken sailors and is plotting to kill Prospero so that he can be free of his bookish master. Needless to say, the crude scheme by the trio of Caliban, Stephano, and Trinculo is easily thwarted by Prospero and his spirit minions.
In the song, “Won’t Get Fooled Again” by The Who, there’re lines that say: “meet the old boss / same as the new boss.” This play focuses heavily on ideas of hostile take over, the inevitable mixed effects, and how tensions are created that will play out. Ariel has at least the promise of being better off — when she works off her debt to Prospero, that is. Caliban is worse off because he is no longer in the power lineage. Caliban’s partners in plotting see a chance to go from being minions aboard a ship to kings of a tiny dynasty on the island. There is also the theme of relinquishing power, and the difficulty of doing so.
Some fun facts about “The Tempest.” First, it’s believed to be Shakespeare’s last play (although evidence is insufficient for certainty.) Second, while Shakespeare’s plays are typically readily divided into three categories: tragedies, comedies, and histories, scholars are a bit divided about which category this play belongs. It’s sometimes categorized as a “tragicomedy” because of its mixed features.
With the storm-washed, rocky island as setting, and the supernatural happenings on the island, this is one of Shakespeare’s eeriest and most mind-bending works.
