An examination of the circumstances of the creation of the Stammheim Missal (Los Angles, J. Paul Getty Museum, MS 64) and the Ratmann Missal (Hildesheim, Dom-Museum, DS 37) in the decades after the monks of St. Michael's at Hildesheim, where the manuscripts were created, had been granted the privilege in 1150 to venerate their founder, Bishop Bernward (d. 1022) as a saint. Proposes that the Stammheim Missal was not intended to be consulted during the mass, the Ratmann Missal serving that requirement, and that it served rather as a repository of the monastery's liturgy and as a sort of contact relic of Bernward.
