But since the knowledge of our maturer years destroys all that, it is with a degree of satisfaction we can turn to the consolations of the fairy mythology. The beloved tales of old are 'not true'--but at least they are not mere idle nonsense, and they have a good and sufficient reason for being in the world; we may continue to respect them. The wit who observed that the final cause of fairy legends is 'to afford sport for people who ruthlessly track them to their origin,'[1] expressed a grave truth in jocular form. Since one can no longer rest in peace with one's ignorance, it is a comfort to the lover of fairy legends to find that he need not sweep them into the grate as so much rubbish; on the contrary they become even more enchanting in the crucible of science than they were in their old character.
