John Pordage (1608-1681), the most remarkable of all English mystics and leader of a school of Christian theosophy, wrote in journal form this extraordinary treatise on the figure of Sophia, divine wisdom. This is the first volume in a series of Pordage's works, brought back into English and published now in his native language for the first time. For those interested in the inner life, mystical practice, and visionary experience, Pordage is a seminal figure and guide, and this volume is essential reading.
