How does Prospero use his magic to exact his revenge in The Tempest?

Prospero begins his magical vengeance by making his servant Ariel create a storm which shipwrecks select passengers. Ariel splits up the passengers, making King Alonso believe his son Ferdinand is dead and vice versa. Perhaps a sidenote to his revenge, Prospero also uses magic to test Ferdinand and his daughter Miranda’s love.

Ariel also puts Gonzalo and Alonso to sleep and then sings to wake them when Sebastian and Antonio attempt to kill them. At Prospero’s command, Ariel sets out a beautiful banquet before transforming into a terrifying harpy and directing the “three men of sin” (Alonso, Sebastian, and Antonio) to confront their evil deeds. Other phantoms appear and torment the men, but the good-hearted Gonzalo cannot see any of this.

Meanwhile, Prospero controls and enacts a kind of revenge on his ungrateful servant Caliban. When Caliban attempts to exact his own vengeance, Ariel chases him and his new masters, Trinculo and Stephano, with a vision of vicious dogs.

In the end, Prospero forgives the men who wronged him, restoring Alonso and Ferdinand and revealing the love between Ferdinand and Miranda. He breaks and buries his staff, drowns his book, and gives up both his magic (“But this rough magic / I here abjure”) and his desire for revenge.
