"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." -- From "The Tempest"
