Benedictional
A Benedictional is a book containing a collection of benedictions or blessings in use in the Roman Catholic Church, essentially collected from those in sacramentary.
The Anglo-Saxon Benedictional of St. Æthelwold is the most famous of the relatively infrequent illuminated manuscript examples, which are mostly Early Medieval.
