Now enjoying cult status since her 're-discovery' 25 years ago, Hildegard von Bingen, the tenth child of an aristocratic family, entered a convent at the age of eight and spent the remainder of her eighty years as a nun as well as a mystic, the latter half as abbess of her own convent. Hildegard's great musico-poetic collection was completed around the year 1150. Symphonia armonie celestium revelationum (Symphony of the Harmony of Heavenly Revelations) is a collection of 77 songs and one music drama. The subjects of these songs are an idiosyncratic collection of individuals and groups - the pieces included on this recording are variously addressed to the Creator, the Redeemer, the Blessed Virgin Mary, St John the Evangelist, Apostles, Confessors, and Martyrs.
