The Mademoiselle de Maupin of real life was a singer at the Opera in Paris at the end of the seventeenth century. She was the daughter of a man of somewhat humble extraction engaged in secretarial work with the Count d’Armagnac; and whilst only a girl married a man named Maupin employed in the province. With him she had lived only a few months when she ran away with a maitre d’armes (_anglicè_, a fencing master) named Serane. If this individual had no other good quality in matters human or divine, he was at least a good teacher of the sword. His professional arts were used in the service of his inamorata, who became herself an excellent swordsman even in an age when swordsmanship had an important place in social life. It may have been the sexual equality implied by the name which gave the young woman the idea, but thenceforth she became a man in appearance;--in reality, in so far as such a metamorphosis can be accomplished by courage, recklessness, hardihood, unscrupulousness, and a willing obedience to all the ideas which passion and sensuality can originate and a greed of notoriety carry into execution. In a professional tour from Paris to Marseilles, in which she as an actress took the part of a man, she gained the affections of the flighty daughter of a rich merchant of Marseilles; and, as a man, ran away with her. Being pursued, they sought refuge in a convent--a place which at that age it was manifestly easier to get into than to get out of. Here the two remained for a few days, during which, by the aid of histrionic and other arts, the actress obviated the necessary suspicions of her foolish companion and kept danger away. All the while La Maupin was conscious that an irate and rich father was in hot search for his missing daughter, and she knew that any talk about the venture would infallibly lose her the girl’s fortune, besides getting herself within the grip of the law. So she decided on a bold scheme of escape from the convent, whereby she might obliterate her tracks. A nun of the convent had died and her body was awaiting burial. In the night La Maupin exchanged the body of the dead nun for the living one of her own victim. Having thus got her companion out of the convent, she set the building on fire to cover up everything, and escaped in secret to a neighbouring village, taking with her by force the girl, who naturally enough was disillusioned and began to have scruples as to the wisdom of her conduct. In the village they remained hidden for a few weeks, during which time the repentance of the poor girl became a fixed quantity. An attempt, well supported, was made to arrest the ostensible man; but this was foiled by the female swordsman who killed one of the would-be captors and dangerously wounded two others. The girl, however, made good her escape; secretly she fled from her deceiver and reached her parents in safety. But the hue and cry was out after La Maupin, whose identity was now known.
