The De partu Virginis and the De assumptione Sanctae Mariae Virginis are important Mariological treatises by the noted Carolingian theologian Paschasius Radbertus. This work presents for the first time an English translation with theological introduction and commentary of the entire volume of Corpus Christianorum Continuatio Mediaevalis (CC CM), volume 56C. The two texts give key insights into the dogmatic development during the post patristic era of the doctrines of Mary's perpetual virgnity (in particular her virginity in partu) and her bodily assumption into heaven. Written for the nuns of the convent of Soisson France, they also provide important source material for the study of female spirituality during the Carolingian Reformation era.
