This magnum opus incorporates more than a century of new research from around the globe, demonstrating how the period from 1350-1550 gave rise to many mystical writers who remain influential today, including Julian of Norwich, Jan van Ruusbroec, and Catherine of Siena. With an unmatched knowledge of primary works and relevant scholarship, McGinn conveys the unique genius of each mystical teacher and describes how the movement built on individual insights. Specific types of mysticism covered include literature in Middle Dutch, and work in Italian and English in the late medieval period. --
