This lecture will look at the 12th century prophetess and visionary Hildegard of Bingen, through the concept of voice. By centring voice, both in the physical and the metaphorical sense of the word, the lecture doesn't focus on a specific work or event from Hildegard's life. Rather, it will considers how Hildegard - in everything she did - understood and used her voice as a form of expression that could lead to earthly and spiritual liberation.
