What makes it significant
-The French were among the first to spread their literary works in the vernacular language and by the fourteenth century, vernacular works spread throughout Europe. This shift from Latin to vernacular language presents an important shift in the interest of courtly literature. The role of women in the rise of vernacular language should also not be underestimated, as it was noble women who commissioned works to be written in or translated to vernacular language
