Why did Christine de Pizan write the book of the city of ladies

Her intention was to defend unwarranted attacks on the characters of women and to provide examples of the unquestionable virtue of her sex. Though this seems like a lofty and daunting goal, it is grounded in a specific response to contemporary events surrounding her life as a writer in France. The Book of the City of Ladies, as a philosophical treatise, can be seen as directly answering the writer Jean de Meun, who between 1269 and 1278 wrote a more than 17,000-line continuation of Guillaume de Lorris’s epic poem The Romance of the Rose, initially completed in the 1230s.
