This collection of legal documents affecting the Christian Church in the Roman Empire is the first its kind in any language. In time the monuments here translated cover the period from the foundation of the Church to the deposition of Romulus Augustulus, the last emperor in the West (476), and to the publication of the second (and only extant) edition of the Code of Justinian I, the most conspicuous champion of Caesaropapism in the East (534)—each terminus ad quem being an arbitrary, but a natural, limit.
