 Medieval author Christine de Pizan solicited the Queen 's patronage at least three times . In 1402 she sent a compilation of her literary argument Querelle du Roman de la Rose — in which she questions the concept of courtly love — with a letter exclaiming " I am firmly convinced the feminine cause is worthy of defense . This I do here and have done with my other works . " In 1410 and again in 1411 , Pizan solicited the Queen , presenting her in 1414 an illuminated copy of her works . In The Book of the City of Ladies , Pizan praised Isabeau lavishly , and again in the illuminated collection , The Letter of Othea , which scholar Karen Green believes for de Pizan is " the culmination of fifteen years of service during which Christine formulated an ideology that supported Isabeau 's right to rule as regent in this time of crisis .
