Christine de Pizan: The City of Ladies I

I think that the interruption by her mother in the prologue is a means for Christine de Pizan to reveal a little bit about herself to the reader. Because she lives at home with her mother we can assume certain things. I originally wanted to say that it could indicate her youth but given the time period it wouldn't be uncommon for a grown woman to be living with her mother, however it would indicate that she is unmarried. This would be an important factor that would effect her writing because as a single woman she would naturally have very different views of marriage and marital relations than a married woman.

Christine de Pizan's apparent gullibility in the prologue does not reflect her true beliefs about the nature of women. She is writing satirically in response to the countless male writers who condemn women as being inferior and believe "that the behavior of women is inclined to and full of every vice". She mocks them by pretending that she shares these beliefs. She claims to have been persuaded that they are correct because it seems that all the writings she comes across are in agreement about the evil nature of women. This tactic is effective because even as she is agreeing with the anti-feminist writings she is disproving them. It is not expected that a woman would be as clever and subtle in her writing as de Pizan is.
Just in case the reader is missing the irony, de Pizan points out her own use of satire through the voice of the women who come to visit her. One asks her why she puts such faith in the words of men who "spoke on many subjects in a fictional way and that often they mean the contrary of what their words openly say", which is exactly what de Pizan herself is doing.
