The Drogo Sacramentary is a Carolingian illuminated manuscript on vellum from c. 850 AD, one of the monuments of Carolingian book illumination. It is a sacramentary, a book containing all the prayers spoken by the officiating priest during the course of the year. In the Sacramentary, Christ is depicted as the central figure, holding the staff of Jacob as he accepts God’s hand and begins his ascension into the clouds, from which God's hand appears.
