 She claims in the preambles to most of these Breton lais that she has heard the stories they contain from Breton minstrels, and it is in the opening lines of the poem "Guigemar" that she first reveals her name to be Marie.There are 102 "Ysopet" fables that have also been attributed to her besides a retelling of the "Legend of the Purgatory of St. Patrick" and, recently, a saint's life called "La Vie seinte Audree" about Saint Audrey of Ely, although this last attribution is not accepted by all critics.Scholars have dated Marie's works to between about 1160 and 1215, the earliest and latest possible dates respectively.
