Restrictions on women’s musical and scholarly pursuits
The Moon and the SunRestrictions on women’s musical and scholarly pursuits shape the terms on which Marie-Josèphe de la Croix can make knowledge and art heard. Her music is judged through a religious rule that Pope Innocent extends beyond the church, while her scholarship is treated as presumptuous or incompetent by men around her. Yet she continues to compose, observe, and speak for herself—and, crucially, to help make the sea woman’s knowledge audible. The constraint is not simply a lack of permission: it is a struggle over who may be recognized as an artist, an investigator, or a credible speaker.
Identity and Scope
The restriction appears across several connected domains rather than as one uniform prohibition. Marie-Josèphe distinguishes her work from her brother Yves de la Croix’s natural philosophy and identifies her own study as mathematics. When an interlocutor assumes that both siblings study alchemy, she corrects the mistake: Yves studies natural philosophy, while she studies a little mathematics. The exchange establishes that her intellectual pursuits are real and specific, even when others’ assumptions recast women’s learning as something ornamental or improper.
Music brings the limits into sharper view. At a performance before Louis XIV, Yves describes his sister as the more talented musician. Pope Innocent responds not by considering the composition on its merits, but by declaring it indecent and invoking the Church’s edict that women should remain silent. Marie-Josèphe knows the rule in its church context, where it had confined the convent to silence; Innocent insists that it applies at all times and calls music injurious to her modesty. His demand that the King censor what he calls pagan excess turns a judgment about one composition into a claim about women’s permissible public expression.
Composition and Supervision
The same presumption surfaces when Marie-Josèphe works on the cantata commissioned by the King. In a small sitting room, she asks for a small harpsichord and brings out her drawing box to begin. M. Coupillet follows her and offers to oversee the work, describing her as both an amateur and a woman and warning that without his help she might offend the King with incompetent work. His offer presents authority over her composition as necessary protection, while making her gender evidence against her competence before the work is judged.
Marie-Josèphe refuses the insult rather than accepting his proposed supervision. M. Coupillet then treats her interests in natural philosophy and music as signs that she is overtaxing her intelligence, and suggests that even the classics would be beyond her next. Lucien de Chrétien intervenes against the premise of this dismissal. He acknowledges that many would deny women the ability to excel as artists or scholars, then exposes the prejudice by comparing it with the claim that no dwarf could ride to war. His argument does not erase the bias surrounding her commission, but it separates social expectation from demonstrated ability.
Scientific Testimony and Credibility
The limits on women’s intellectual authority also govern who is allowed to interpret evidence. During a demonstration before natural philosophers, Marie-Josèphe explains that the sea woman is displaying her ability to breathe underwater. The senior scholar ridicules her, saying she has mistaken the creature for a fish, and the assembled men laugh. Their response makes her interpretation a target of contempt before it has been tested.
Marie-Josèphe answers in Latin, stating that the sea woman’s lungs possess an anomalous lobe unique to the sea people. Yves tells her that her comments are of no interest. She recognizes that he fears she will reveal the secret—but understands that what she has offered is a false secret. The exchange shows her navigating a room in which her speech is discounted and scientific information is strategically withheld. Her learning does not grant her equal control over what counts as evidence or who may disclose it.
Lucien de Chrétien argues for a different standard when the sea woman’s status is debated before the King and Pope. He says that Marie-Josèphe has proved the creature understands her, and proposes that what remains to be established is whether the creature speaks a human language. Invoking the demand for proof associated with a scientific age, he asks Louis XIV to let her demonstrate her contention. Louis agrees to see. The concession is limited, but it makes room for a test of Marie-Josèphe’s claim rather than treating her judgment as disqualifying simply because it is hers.
Voice, Translation, and Belief
Marie-Josèphe’s position becomes more complex when she carries the sea woman’s account into the royal and religious audience. As she considers whether to make the sea woman sound more diplomatic, she decides not to tangle herself in lies and expects the sea woman to correct her. The moment presents her not as a neutral mouthpiece but as a responsible interpreter who must choose between smoothing a difficult message and preserving its truth. The sea woman’s own capacity to speak and correct her matters: the exchange depends on recognizing a voice that the court’s categories have not readily admitted.
That responsibility becomes perilous when Marie-Josèphe sings the sea woman’s account of life and death. In response to questions about immortality and resurrection, she conveys the sea woman’s belief that life continues through living beings creating new life, while the dead do not return. Pope Innocent reacts with disgust and accuses Marie-Josèphe of approaching heresy. She answers that she did not invent the story and asks him to believe her; the sea woman, she explains, does not understand heresy. The conflict therefore reaches beyond permission to perform: Marie-Josèphe is held answerable for knowledge she has received and translated, even as the religious authority condemning it refuses the source the same standing.
Significance
Across music, mathematics, natural philosophy, and translation, the recurring barrier is the gap between a woman’s capacity and the authority others grant her. Marie-Josèphe’s composition can be called indecent, her scholarship a strain on her intelligence, and her scientific explanation a cause for laughter; in each case, judgments about her position threaten to substitute for engagement with what she has made or observed. Yet the narrative also gives her concrete intellectual work: she distinguishes disciplines, composes for the King, offers an anatomical claim, and mediates a contested testimony without pretending it originated with her.
The resulting conflict is not resolved by a single advocate or royal permission. Lucien’s defense and Louis XIV’s willingness to allow proof create openings, while Pope Innocent’s pronouncements and the scholars’ scorn show how readily those openings can be narrowed. Marie-Josèphe’s persistence makes the restriction visible as a contest over voice and credibility: who may create, who may interpret, and whose account can be heard as knowledge rather than dismissed as female excess.
