the tempest act four

Prospero stops Ferdinand's punishment, and decides to finally give Miranda to him, since he has proven his love for her through his service. Prospero accepts the union, but issues them a warning; if Ferdinand takes Miranda's virginity before a ceremony can be performed, then their union will be cursed. Ferdinand swears to Prospero that they shall wait until the ceremony to consummate their marriage, and then Prospero calls upon Ariel to perform one of his last acts of magic. A betrothal masque is performed for the party by some of Prospero's magical spirits.
