Alexander of Lycopolis, Ante-Nicene Fathers Vol. VI — Introductory Notice (1885)
“ The ecclesiastical rulers of the dioceses were called patriarchs, exarchs, or archbishops, of whom there were fourteen; the rulers of the provinces were styled metropolitans, i.e., governors of the μητρόπολις or mother city, and those of each city and its districts were called bishops. ”
