Prospero is a fictional character and the protagonist of William Shakespeare's play The Tempest. Prospero is the rightful Duke of Milan, whose usurping brother, Antonio, had put him to sea on a "rotten carcass" of a boat to die, twelve years before the play begins. Prospero and Miranda had survived and found exile on a small island. He has learned sorcery from books, and uses it while on the island to protect Miranda and control the other characters.

The Tempest is a play by William Shakespeare, probably written in 1610–1611, and thought to be one of the last plays that he wrote alone. After the first scene, which takes place on a ship at sea during a tempest, the rest of the story is set on a remote island, where Prospero, a complex and contradictory character, lives with his daughter Miranda, and his two servants: Caliban, a savage monster figure, and Ariel, an airy spirit. The play contains music and songs that evoke the spirit of enchantment on the island. It explores many themes, including magic, betrayal, revenge, and family. In Act IV, a wedding masque serves as a play-within-a-play, and contributes spectacle, allegory, and elevated language.
