Bible Missals are manuscripts that integrate liturgical prayers for the Mass with the scriptural texts of the Latin Vulgate. Long overlooked by scholars, Bible Missals offer important evidence for the development of the medieval liturgy and the liturgical use of scripture by medieval Christians. This monograph is the first comprehensive analysis of the codicology and contents of Bible Missals. Mostly produced in the first half of the 13th century by professional book makers in centers like Paris and Oxford, these hybrid manuscripts were customized for secular, monastic, and mendicant patrons. This monograph focuses on Dominican Bible Missals, the largest group within the repertoire, providing detailed codicological descriptions of each manuscript and analyzing their texts for the Order of Mass and selected liturgical formularies, including prayers for the feast of St. Dominic. For medieval Christians, the words and events of scripture were continually called to mind and reenacted in the sacramental rites of the Mass. Bible Missals provide important material evidence for this interplay between word and sacrament.
