The allegory is a more general narrative type; it also employs metaphor. Like the parable, the allegory makes a single, unambiguous point. An allegory may have multiple noncontradictory interpretations and may also have implications that are ambiguous or hard to interpret. As H.W. Fowler put it, the object of both parable and allegory "is to enlighten the hearer by submitting to him a case in which he has apparently no direct concern, and upon which therefore a disinterested judgment may be elicited from him, ..." The parable is more condensed than the allegory: it rests upon a single principle and a single moral, and it is intended that the reader or listener shall conclude that the moral applies equally well to his own concerns.
