As the Dauphin himself was growing up, Christine dedicated three works to him, advising him on wise and effective government. One of these works, Livre du Corps de policie ("The Book of the Body Politic") described the governments of medieval Europe. In it, she criticized the Italian city-states of her birth that were run by corporations, favoring hereditary monarchies that she felt were better for the common good. Much of this book covered the king's duties as a military leader.
Perhaps it was those chapters that inspired a gift of 200 livres* to her for writing Livre des fais d'armes et de chevalerie ("The Book of Feats of Arms and of Chivalry"). In it, she explains the rationale for a "just war" and quotes classical writers on warfare. She rejected Trial by Combat, discussed proper treatment of noncombatants and prisoners of war, and claimed that only a king can start a war because the king is responsible for the welfare of his people and country. One year after producing this book, nobles were prohibited from raising armies by royal edict.
In 1413, Christine followed this work with Livre de la paix ("The Book of Peace"), her thoughts on good governance. This was a time of civil war in France, and she urged the Dauphin to seek peace, quoting writings of Abelard, St. Benedict, and Cicero.
The Dauphin's mother, Queen Isabeau, requested of Christine her collected works. In 1414, Christine presented the queen with a lavishly illustrated compendium of 30 of her writings. The illustration above is the frontispiece, with Christine presenting the work to Isabeau.
There was a long period away from court when she wrote less. It is assumed she was avoiding the stress of civil war by staying in a Dominican convent, but in 1429 she came out with another work at the end of the civil war. That was a poem, DitiƩ de Jehanne d'Arc ("The Tale of Joan of Arc"). I'll talk about that, and Joan, tomorrow.
