This chapter discusses a group of manuscripts which carry some of the oldest examples of the ordines romani. The texts are together termed the ‘Roman’ Collection, and it was assumed they were put together from the texts of purest Roman origin to propogate the adoption of Roman liturgy in Francia. However, examination of the manuscripts reveals a much less focused or immediate gathering of the texts, and shows that none of the given texts are indisputably Roman in origin. Individual manuscripts also continually changed how the Collection was presented and conceived, adding more individual texts of Frankish conception to it. The Collection is traced back to Carolingian Metz, where an experiment in the creative adoption of Roman liturgy was being undertaken.
