The story of la Maupin's assault on Marguerite Fouré with a large key provides a lot of material for her story. Not only does the incident illustrate her temper and character, but the records give us myriad little facts: names, places, relationships and the like. As is always the case, many of these just brush the surface and raise even more questions than they answer. In this posting, i will try to run down the salient bits.
So far, I have three sources that recount the incident, all of which cite primary sources, often quoting them. These are Oscar Paul Gilbert's "Women in Men's Guise", published in English in 1932, and Gabriel Letainturier-Fradin's "La Maupin (1670-1707): sa vie, ses duels, ses aventures", published in French in 1904, and Émile Campardon's "L'Académie royale de musique au XVIIIe siècle". It is quite possible that Gilbert takes his information from Letainturier-Fradin rather than the original sources. Letainturier-Fradin cites the specific primary sources. Campardon reproduces the commissioner, Regnault's report.
Gilbert's account is relatively short. He writes,
In 1700, la Maupin was living in some rather nice quarters in the Rue Saint-Honoré. Unfortunately she could not get on at all with her landlord.
One night, it was the 6th September 1700, she got home about nine o'clock and told her landlord she wanted supper. As he did not comply with sufficient alacrity for her liking, she seized a spit which was hanging against the chimney-piece and began to belabor the poor man's face with it. Menservants and maidservants tried to intervene, but in less than no time they were all out of action.
The magistrate was called to the scene of the conflict and drew up the following report:
[Report elided — JLB]
Having drawn up his report, the man of law withdrew in order to lodge his precious rigmarole in the proper quarter. Next day the witnesses were called, servants and shopkeepers of the neighborhood, who all deposed that they had seen la Maupin, a singer at the Opera, lying on the kitchen floor struggling wildly with a maid servant. Finally a surgeon certified in writing that he had "visited, and given professional attention to Marguerite Foret, a servant in the establishment of the Sieur Langlois, and that she had a wound on the forehead as well as several contusions and abrasions on the forearm.
Things came to such a pass that, yet once again, la Maupin was compelled to have recourse to her protector-in-ordinary, owing to whose representations the action against her was withdrawn.
To this Letainturier-Fradin adds considerable detail (p. 147). He gives not only the text of the magistrate's report, but that of a number of depositions made by witnesses the next day. From these we learn that
- Mlle Maupin, M. Langlois and Marguerite Fouré, the cook, resided on the rue Traversière
- La Maupin's "sister" and two lackeys were present
- The neighbors include
- Rene Mérot, working at master tailor sieur Rabier's shop, which was adjoining on the rue Traversière
- M. Verand Raphaely, valet to the Marquise de Vance, who also lived in an adjoining house
- Marie Soufflart, wife of master saddler Michel Bauchet, who also lived nearby
- Marie-Anne Bauchet, their daughter
- Marguerite Fouré was attended to by M. Desportes, a surgeon of the King.
- Despite all the evidence, she apparently wasn't charged or punished.

The rue Traversière runs diagonally one block east of the Palais Royal, home of Monsieur—the Duc d'Orleans, the King's brother—and can be seen in both the 1705 and Turgot maps of Paris.The picture above shows it as it was about 30 years after her death, when Turgot commissioned his map. As can be seen in the picture, an even narrower street led into the interior of the block. It's labelled the "Rue de la Brasserie" or "street of the brewery". The surgeon says in his deposition "sieur Langlois, demeurant rue Traversière en porte cochère". Sadly, my French is very poor and I do not know if the phrase "en porte cochère", which translates as something like "in gate" tells us anything of where along the street M. Langlois and la Maupin reside.
The rue Traversière still exists today, renamed as "Rue Molière", and a few of the buildings as seen in Google street view do not seem terribly different from the way they may have appeared in 1700. Imagining la Maupin's "sister" leaning out one window and calling out to someone in a window across the way is not too difficult.
Which brings us to the question of that supposed sister. Who is she? An actual sister we haven't heard of previously or perhaps a roommate or lover? Letainturier-Fradin writes:
Etant donné les mœurs de la chanteuse, il se pourrait qu'elle ait fait passer pour sa parente une femme avec qui elle vivait.
which I take to mean something like:
Given the mores of the singer, she could have passed on her parent to a woman with whom she lived.
It is a very reasonable theory, and one that lends itself to a number of story-telling possibilities. If she is a paramour, we have very little further clue to her identity, and I'm pretty much free to write her as I choose.
Along with her "sister", la Maupin is accompanied by two "lackeys" ("laquais" in French). In either French or English, that term originally meant a liveried servant, one who wears your arms or colors. Over time it shifted to any servant and then someone who is particularly servile, and unsavory, a "henchman". Adolphe Julien devotes the last chapter of "The opera before the revolution, the reign of Louis XIV, and the regency" to the role of the lackey at the beginning of the 18th century. He writes that,
Furetiere's Dictionary thus defines a lackey: "A valet not of noble birth (roturier) who follows his master on foot, who wears his liveries." The word roturier is not so much a pleonasm as one would believe. Indeed, if you open the book published by Audiger towards the end of the seventeenth century—La Maison réglée—you will see that the three orders were represented in the home of a great gentleman; the nobility, by the gentleman or lady in waiting, the pages, and the squire; the clergy, by the almoner and often the tutor; the third order or the bourgeoisie, by the steward, the secretary, the major-domo, to whom may be added the porter or "Swiss" and valets de chambre. As for the lackey, he was part of the common people like the grooms, the postilions, the cooks, and the stable-boys ; but he stood apart from the nameless swarm by his sharp-cut character.
La Maupin herself was the daughter of a bourgeois servant. Her father, Gaston d'Aubigny, was the comte d'Armagnac's secretary. However, by 1700 she was quite wealthy, at least for a commoner. Gilbert gives her salary as 3,000 livres per year. Julien gives the wages of a lackey as on the order of 90-120 livres a year. It should not be beyond her means to hire a pair of actual lackeys. Then, too, they may be hangers on, 18th century groupies or roadies. We know that along with fencing she enjoyed riding. She might have a groom or other common servant, whom Regnault might describe as "lackeys".
I have been unable to find anything on the marquise de Vance, la Maupin's neighbor.
