Hildegard of Bingen OSB (German: Hildegard von Bingen; Latin: Hildegardis Bingensis; 1098 – 17 September 1179), also known as Saint Hildegard and the Sibyl of the Rhine, was a German Benedictine abbess, writer, composer, philosopher, Christian mystic, visionary, and polymath of the High Middle Ages. She is one of the best-known composers of sacred monophony, as well as the most-recorded in modern history. She has been considered by many in Europe to be the founder of scientific natural history in Germany. Attention in recent decades to women of the medieval Church has led to a great deal of popular interest in Hildegard’s music. In addition to the Ordo Virtutum, sixty-nine musical compositions, each with its own original poetic text, survive, and at least four other texts are known, though their musical notation has been lost. This is one of the largest repertoires among medieval composers.
