The Santa Barbara Bible (University of California, Santa Barbara, University Library MS BS 75 1250) was first introduced to scholarship in 1971 by Santa Barbara professor Larry Ayres. In the years since that pioneering study, art historians have advanced our knowledge of the place and date of the Bible’s production. Adding to that an understanding of commercial manuscript production in thirteenth-century Paris, the present article comes as close to clarifying the creation of this lovely book as current evidence allows.
