Task: Text Categorization
Input (English): One of this composer's works opens with the sacrifice of a "milk-white steed" to Woden, and later Cupid sings "In spite of cold weather, I've brought you together" as part of a play-within-a-play. That occurs in this composer's collaboration with John Dryden, who wrote the libretto to that semi-opera, King Arthur. This composer also collaborated with Nahum Tate on a full opera in which an evil sorceress, observing the title characters' love, resolves that she can destroy the kingdom by inducing one of them to believe he has a city to found elsewhere. The witch correctly predicts that the abandoned lover will die of grief, which she does after singing the aria "When I am laid in Earth." For ten points, name this English composer, creator of Abdelazer and Dido and Aeneas.
