They scoured all the texts since forever and could only find this:
The medieval court case of Eleanor Rykener shows a legal system that is trying to square a person who lives as a woman, and calls herself Eleanor, with other information that leads the court to identify Eleanor as a man named John. In the testimony of this late 14th century London trial, Eleanor is brought into the courts on accusations of sexual misconduct—she was caught in the act performing sex work. However, sex work was often tolerated in London at this time; the problem is not the sex work. The problem is that the court does not know whether or not sodomy was committed.
The court does not know, or rather cannot decide, because they cannot decide whether or not Eleanor is a man or a woman. She gives her name as Eleanor, and presents as a woman to the courts. But after interrogation, she is forced to confess that she once lived in London as a man named John. She tells the story of her transition, and her new work as a seamstress and sex worker. She discusses sleeping with both men and women—from aristocrats to nuns and priests—some of whom offered her pay or presents.
In the end, a verdict is not recorded. Indeed, while the text records both the names “Eleanor” and “John,” it is written in Latin, which allowed for the proceedings to continue without the male or female pronouns frequently required by English or French. The court, it seems, did not want to decide on a pronoun because they were still trying to decide what gender to consider Eleanor. Thus, history is left with a record of a trans woman, and also a record of the conflict which is textbook gender dysphoria: a marked difference between the individual’s expressed/experienced gender, and the gender others would assign to him or her.
What was the reading you took from this then? If it wasn't about how declaring he was a woman was to avoid the accusation of sodomy?
