The contemporaries of Hildegard of Bingen called her "prophetissa teutonica", honouring her philosophical writings and interpretation of the cosmos. Mediaevalists still consider her one of the leading mystics, and point to her active spiritual and artistic life in the 12th century as the finest example of what a woman can achieve. The abbess Hildegard of Bingen was the first composer to sign her musical works. As a playwright and author, she witnessed and shaped the time of the Crusades, the literary minnesang, and political and theological debate. The author of this text draws a complex picture of her life and work, as he "translates" Hildegard's ideas and her mysterious world of symbols from mediaeval Latin into contemporary concepts. Heinrich Schipperges delineates this remarkable thinker's view of the human being as a microcosm of the universe, intricately bound by the senses to the life of the soul, nature, and God.
