Born into a noble family, she was instructed for ten years by the holy woman Blessed Jutta. When Hildegard was 18, she became a Benedictine nun at the Monastery of Saint Disibodenberg. Ordered by her confessor to write down the visions that she had received since the age of three, Hildegard took ten years to write her Scivias ( Know the Ways ). Pope Eugene III read it and in 1147 encouraged her to continue writing. Her Book of the Merits of Life and Book of Divine Works followed. She wrote over 300 letters to people who sought her advice; she also composed short works on medicine and physiology, and sought advice from contemporaries such as Saint Bernard of Clairvaux.
