Christine de Pizan's Livre de la Cité des Dames (1405) is justly renowned for its full-scale assault on the misogynist stereotypes which dominated the culture of the Middle Ages. Rosalind Brown-Grant locates the Cité in the context of Christine's defence of women as it developed over a number of years and through a range of different texts. Arguing that Christine tailored her critique of misogyny according to the genre in which she was writing and the audience she was addressing, this study shows that Christine's case for women nonetheless had an underlying unity in its insistence on the moral, if not the social, equality of the sexes. Whilst Christine may not have been a radical in modern feminist terms, she was able to draw upon the cultural resources of her day in order to construct an intellectual authority for herself that challenged the prevailing orthodoxy of the day.
