Now, in reality, Olympia was not a human being at all, but merely a marvellously life-like automaton, made by Spallanzani, who had been assisted in the work by another scientist named Coppelius, a mysterious man who had gained a considerable reputation as a wizard and dabbler in the occult arts; but, seeing that young Hoffmann had no knowledge of the wonderful piece of mechanism they had contrived to make, but believed the latter to be indeed a real flesh-and-blood maiden, the pair conspired together to keep him in this belief, in order to retain him longer as a pupil, and also to amuse their friends at his expense.

Consequently, they would not permit Hoffmann any closer inspection of Olympia until the night of the party; and the magician, Coppelius, next informed the young man that his sight was bad, and sold to him a pair of specially prepared spectacles through which he knew that the automaton would appear to him to be indeed a living person.

Coppelius, seeing that a large fortune could probably be made by exhibiting the mechanical figure, now claimed a substantial share in the anticipated profits, he having made half of her body and supplied her with her beautiful eyes; so Spallanzani agreed to buy him out, and to that end gave him a draft on a Jew—knowing the latter to be bankrupt, but craftily concealing the fact from Coppelius, whom he believed was about to depart from the country, and, consequently, would not be likely to discover the fraud until many miles had separated them.

Coppelius, quite unsuspicious, accepted the false draft and departed; and on the same day Spallanzani gave his grand entertainment in honour of the coming-out of his beautiful "daughter."

When all the guests had arrived, the scientist produced the exquisitely made life-sized doll, dressed daintily in pretty girlish garments; and the automaton, having been wound up beforehand, was led round the ball-room by Spallanzani with great pride, and bowed to the guests, greeting them in clear, bell-like tones, and finally singing to them a fine operatic song, full of such finished trills and flourishes that the audience was astounded by the wonderful performance.

The visitors, of course, knew perfectly well that the figure was merely an automaton; but seeing that young Hoffmann—who was wearing the magic spectacles that caused the doll to appear to him more than ever to be a real human being—thought otherwise, they merrily conspired with Spallanzani to pretend that Olympia was indeed his daughter.

Becoming more and more enamoured of the pretty "maiden," as he gazed admiringly at her through his strange spectacles, Hoffmann was at last completely bewitched by her pink-and-white waxen beauty; and sitting down beside her, he took the first opportunity of their being alone to declare his passion for her, utterly regardless of her stolid attitude, stiff, jerky movements and mechanical replies of "Yes! Yes!" to all he said.

So enraptured was he that he became entirely oblivious of his surroundings, continuing to pour forth tender love speeches into the unheeding ears of the pretty Olympia, to the great amusement of the other guests; and when his friend, Nicklaus, who was also present, tried to enlighten him as to the true state of affairs, he thrust him aside roughly, and devoted himself more assiduously than ever to the unresponsive doll.

When dancing began he immediately engaged her as his partner, lovingly encircling her slender waist with his ready arm; but the doll, having been overwound, now got out of control, and whirled the unfortunate Hoffmann round and round the room at so dizzy a pace that he at length fell to the ground in a swoon, Olympia spinning on alone until finally caught and placed in the laboratory once more.

At this moment, to the dismay of Spallanzani, the wizard, Coppelius, rushed into the house in a towering rage, having discovered the fraud which had been practised upon him and returned to wreak vengeance upon his false partner by destroying the mechanical doll; and hastening to the laboratory, he managed to break the wonderful automaton into little pieces before his brother scientist could prevent him.
