The importance of the virgin martyrs as the focus of devotion and models for proper feminine behavior increased during the Late Middle Ages.[29][30][31] Among these, St Catherine in particular was used as an exemplar for women, a status which at times superseded her intercessory role.[32] Both Christine de Pizan and Geoffrey de la Tour Landry point to Catherine as a paragon for young women, emphasizing her model of virginity and "wifely chastity."[33][34][35] From the early 14th century the mystic marriage of Saint Catherine first appears in hagiographical literature and, soon after, in art.
