Hildegard of Bingen (1098 - 1179), also known as Saint Hildegard and Sibyl of the Rhine, was a writer, composer, philosopher, Christian mystic, German Benedictine abbess, visionary, and polymath. Elected a magistra by her fellow nuns in 1136, she founded the monasteries of Rupertsberg in 1150 and Eibingen in 1165. One of her works as a composer, 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 arguably the oldest surviving morality play, while supervising brilliant miniature Illuminations.
