There are 26 extant man­u­scripts of the Book of the City of Ladies, plus 22 of the Trésor de la Cité des Dames, which she also com­pleted in 1405. Many of those man­u­scripts have illu­mi­na­tions also designed by Christine herself, like the Book of the Queen or the man­u­script linked in this article:

Christine de Pizan. Livre de la Cité des Dames. Bib­lio­thèque Nationale de France. Ms. fonds français 1177.

This is probably Christine de Pizan’s most read work in our times (but not in her times), and has been trans­lated and com­mented extensively.
