Prospero, the Duke of Milan, was a learned and studious man, who lived among his books, leaving the management of his dukedom to his brother Antonio, in whom indeed he had complete trust. But that trust was ill-rewarded, for Antonio wanted to wear the duke's crown himself, and, to gain his ends, would have killed his brother but for the love the people bore him. However, with the help of Prospero's great enemy, Alonso, King of Naples, he managed to get into his hands the dukedom with all its honor, power, and riches. For they took Prospero to sea, and when they were far away from land, forced him into a little boat with no tackle, mast, or sail. In their cruelty and hatred they put his little daughter, Miranda (not yet three years old), into the boat with him, and sailed away, leaving them to their fate. But one among the courtiers with Antonio was true to his rightful master, Prospero. To save the duke from his enemies was impossible, but much could be done to remind him of a subject's love. So this worthy lord, whose name was Gonzalo, secretly placed in the boat some fresh water, provisions, and clothes, and what Prospero valued most of all, some of his precious books. The boat was cast on an island, and Prospero and his little one landed in safety. Now this island was enchanted, and for years had lain under the spell of a fell witch, Sycorax, who had imprisoned in the trunks of trees all the good spirits she found there. She died shortly before Prospero was cast on those shores, but the spirits, of whom Ariel was the chief, still remained in their prisons. Prospero was a great magician, for he had devoted himself almost entirely to the study of magic during the years in which he allowed his brother to manage the affairs of Milan. By his art he set free the imprisoned spirits, yet kept them obedient to his will, and they were more truly his subjects than his people in Milan had been. For he treated them kindly as long as they did his bidding, and he exercised his power over them wisely and well. One creature alone he found it necessary to treat with harshness: this was Caliban, the son of the wicked old witch, a hideous, deformed monster, horrible to look on, and vicious and brutal in all his habits.
