Argumentative and Anecdotal
You only need to read a few chapters of this book to realize that Christine de Pizan uses the same writing formula over and over to make her points. She'll ask one of her three magical lady characters about a feminine stereotype, then have the ladies prove the stereotype wrong by giving lots of examples of women who don't fit this stereotype. Along the way, some of her stories can get really violent, as we read at one point:
After this story, Rectitude told me many others which I will omit for the sake of brevity, such as, for instance, the one about Leaena, a Greek woman who, in spite of all the torture used on her, refused to accuse the two men with whom she was associated, but instead bit her own tongue off with her teeth in front of the judge so that he would have no chance of making her talk using torture. (2.53.1)
It's funny that de Pizan says she'll leave certain stories out for the sake of "brevity" (or to save time), since this book contains more than enough stories to convince anyone of women's goodness. But then again, maybe we should be thankful that the book isn't twice as long, which it definitely could have been, according to de Pizan.
