Hildegard of Bingen:
1098-1179,German composer, abbess and mystic. Her writings include much lyrical and dramatic poetry which has survived with monophonic music. The Symphonia armonie celestium revelationum contains musical settings of 77 poems arranged according to the liturgical calendar. The poetry is laden with imagery and the music, based on a few formulaic melodic patterns, is in some respects highly individual. Her morality play Ordo virtutum contains 82 melodies in a more syllabic style.
