MM. Michel Carré and Jules Barbier, who made the book for Gounod's opera "Faust," went for their subject to Goethe's dramatic poem. Out of that great work, which had occupied the mind of the German poet for an ordinary lifetime, the French librettists extracted the romance which sufficed them--the story of Gretchen's love for the rejuvenated philosopher, her seduction and death. This romance is wholly the creation of Goethe; it has no place in any of the old legends which are at the bottom of the history of Dr. Faust, or Faustus. Those legends deal with the doings of a magician who has sold his soul to the devil for the accomplishment of some end on which his ambition is set. There are many such legends in mediaeval literature, and their fundamental thought is older than Christianity. In a sense, the idea is a product of ignorance and superstition combined. In all ages men whose learning and achievements were beyond the comprehension of simple folk were thought to have derived their powers from the practice of necromancy. The list is a long one, and includes some of the great names of antiquity. The imagination of the Middle Ages made bondsmen of the infernal powers out of such men as Zoroaster, Democritus, Empedocles, Apollonius, Virgil, Albertus Magnus, Merlin, and Paracelsus. In the sixth century Theophilus of Syracuse was said to have sold himself to the devil and to have been saved from damnation only by the miraculous intervention of the Virgin Mary, who visited hell and bore away the damnable compact. So far as his bond was concerned, Theophilus was said to have had eight successors among the Popes of Rome. Architects of cathedrals and engineers of bridges were wont, if we believe popular tales, to barter their souls in order to realize their great conceptions. How do such notions get into the minds of the people? I attempted not an answer but an explanation in a preface to Gounod's opera published by Schirmer some years ago, which is serving me a good turn now. For the incomprehensible the Supernatural is the only accounting. These things are products of man's myth-making capacity and desire. With the advancement of knowledge this capacity and desire become atrophied, but spring into life again in the presence of a popular stimulant. The superstitious peasantry of Bavaria beheld a man in league with the devil in the engineer who ran the first locomotive engine through that country, More recently, I am told, the same people conceived the notion that the Prussian needle-gun, which had wrought destruction among their soldiery a the war of 1866, was an infernal machine for which Bismarck had given the immortal part of himself.
