Only five manuscripts containing some or all of Marie’s lais exist now, and the only one to include the general prologue and all twelve lais is British Library MS Harley 978. That may be contrasted with the 25 manuscripts with Marie's "Fables" and perhaps reflects their relative popularity in the late Middle Ages. In these Fables, she reveals a generally aristocratic point of view with a concern for justice, a sense of outrage against the mistreatment of the poor, and a respect for the social hierarchy. Nevertheless, Marie's lais have received much more critical attention in recent times.
