Blessed Hildegard of Bingen (German: Hildegard von Bingen; Latin: Hildegardis Bingensis; 1098 – 17 September 1179), also known as Saint Hildegard, and Sybil of the Rhine, was a Christian mystic, German Benedictine abbess, visionary,and polymath. She became a nun at age 15. Elected a magistrate (abbess) by her fellow nuns in 1136, she founded the monasteries of Rupertsberg in 1150 and Eibingen in 1165. She was a composer with an extant biography from her own time. One of her works, the Ordo Virtutum, is an early example of liturgical drama. She wrote theological, botanical and medicinal texts, as well as letters, liturgical songs, poems, and the first surviving morality play, while supervising brilliant miniature Illuminations.
