Ferdinand is the prince of Naples and the son of Alonso, the King of Naples, in Shakespeare's play, The Tempest. He falls in love with Miranda. He is quick to promise the title of queen and wife to Miranda even though he doesn't know her name. He is happy in humble labours, blinded by love. He makes a solemn vow to be truthful to Prospero, and not to violate Miranda's chastity before their wedding.
