Angel
Angels are generally held to be holy and virtuous, hence the term is used loosely to apply to anyone particularly good or kind, or having a good influence. In his novel Far From the Madding Crowd, Thomas Hardy chooses the name of an angel, Gabriel, for his kind and helpful hero. On the other hand, in his play Measure for Measure, Shakespeare's use of the name Angelo is ironic, since Angelo is a character who likes to see himself as virtuous, but who is concealing evil aspects of his nature. Fallen angels, who are no longer holy or virtuous, are also known as devils.
