 Themes in her work include the spirituality of women in the late Middle Ages ("Ancrene Riwle"), and the contradictions and impossibilities in the work of Richard Rolle.In work on both the "Ancrene Riwle" and "Margery Kempe", she identified a need for a "history of culture", extending both the range of material to be considered, and the kinds of questions to be asked.In 1910, she presented evidence that Rolle was not the author of "The Prick of Conscience", in the Radcliffe Monographs.
