Note 511 — Chapter XVI
Reading edition
Labbé, ii. p. 947. It must always be borne in mind that Diocese was the name of the largest civil division of the Roman Empire. Each diocese contained several provinces, e.g. Thrace, six; Asia, ten; Pontus, eleven. The whole Empire was divided into thirteen dioceses, and about one hundred and twenty provinces. The Ecclesiastical divisions followed more or less the plan of the civil. An archbishop was bishop of the metropolis of a Province, a Patriarch of one or more Dioceses.
