The Tempest is a play by William Shakespeare, estimated to have been written in 1610-11,[1] although some researchers have argued for an earlier dating.[2] The play's protagonist is the banished sorcerer Prospero, rightful Duke of Milan, who initially uses his magical powers to punish his enemies when he raises a tempest that drives them ashore. The entire play takes place on an island under his control whose native inhabitants, Ariel and Caliban, respectively aid or hinder his work.Shakespeare, William - Adaptations. Source: SBS 14/02/2007
