Ordo Virtutum-The Ritual of the Virtues

Ordo Virtutum is an allegorical morality play, or sacred music drama, by Hildegard of Bingen, composed around 1151, during the construction and relocation of her Abbey at Rupertsberg. It is the earliest morality play by more than a century, and the only medieval musical drama to survive with an attribution for both text and music.
