This study investigates the persistence and functional utility of Byzantine canon law manuscripts in Southern Italy following the Norman conquest. James Morton examines how Greek-speaking Christian communities maintained their legal and religious identity through the continued use of specific liturgical and canonical texts long after the collapse of Byzantine political administration. The work argues that these manuscripts served as vital instruments for preserving cultural autonomy and ecclesiastical tradition within a shifting geopolitical landscape.

Scholars in the field of medieval Mediterranean history recognize this text as a specialized contribution to the study of Byzantine legal survival in Western Europe. The prose is noted for its academic rigor and focus on codicological evidence, making it a valuable resource for researchers interested in the intersection of law, religion, and cultural identity.
