In this final chapter, the presentation of the ordo romanus manuscripts is discussed. Their use of innovative script forms and patterns of script use to highlight points of interest to their compilers is analysed. The characteristics of their physical format and layout are used to suggest potential uses and users. Finally, the employment of Latin in the texts is discussed, showing how certain scribes saw no problem recording the ordines in a form of Latin later characterised as ‘debased’. This questions the assumed notion of a wholesale reform of Latin and liturgical Latin in particular. The deployment of Greek in several ordines is also discussed, as a counterpart.
