Ordo Virtutum

Ordo Virtutum (Latin for Order of the Virtues) is an allegorical morality play, or liturgical drama, by Hildegard of Bingen, composed c. 1151. It is the earliest morality play by more than a century, and the only Medieval musical drama to survive with an attribution for both the text and the music.

A short version of Ordo Virtutum without music appears at the end of Scivias, Hildegard's most famous account of her visions. It is also included in some manuscripts of the Symphonia armoniae celestium revelationum ("Symphony of the Harmony of Celestial Revelations"), a cycle of more than 70 liturgical songs. It may have been performed by the convent nuns at the dedication of the St. Rupertsberg church in 1152 or possibly before the Mass for the Consecration of Virgins at the convent .
