For the good are always the merry, / Save by an evil chance,/ And the merry love the fiddle,/ And the merry love to dance: / And when the folk there spy me,/ They will all come up to me, / With,โHere is the fiddler of Dooney!โ / And dance like a wave of the sea.
William Butler YeatsA symbol is indeed the only possible expression of some invisible essence, a transparent lamp about a spiritual flame; while allegory is one of many possible representations of an embodied thing, or familiar principle, and belongs to fancy and not to imagination: the one is a revelation, the other an amusement.
William Butler Yeats
