Most parts of this missal, some of with neumes, were produced in
about 1100. After 1200 they were bound together with a more recent
addition. The characteristic initials with twining branches, the
inclusion of the feast days of local saints in the calendar, the
additional section, and other addenda indicate that the missal was
produced in the monastery of Allerheiligen (All Saints) in
Schaffhausen and remained in use there over the course of many
centuries. It is one of the few liturgical manuscripts from this
monastery that survived the Reformation.
