This essay considers the influence and reception of the writings of Christine de Pizan, whose career was caught up in the Anglo-French conflict of the Hundred Yearsߣ War, as illustrated by her LߣEpistre dߣOthéa, a didactic treatise on chivalry and virtue, and her autobiographical LߣAdvision Christine. Warren explores the shifting significance of the Othéa during the fifteenth and sixteenth centuries, showing that Stephen Scropeߣs English translation reduced female agency and power, changes that reflected wider cultural anxieties concerning female lineage and virtue in the context of Lancastrian claims to the throne. The essay also explores Christineߣs connections to two other powerful women: Joan of Arc and Margaret of Anjou. By reworking Christineߣs treatments of women to reduce their political power and independent wisdom, translators of Christineߣs works also contained the political threats represented by powerful women. Strikingly, depictions of Christine as author shift her context from the court to the cloister, reaffirming traditionally gendered views of women even while her works continued to be circulated in England.
