The Nicene Age

Who Maternus of Cologne was

The first historically certain bishop of Cologne — one of the three Gaulish bishops Constantine personally summoned to sit with Miltiades at the Lateran hearing of the Donatist case in 313, and a subscriber at Arles the next year. Later legend made him a disciple of Peter; the documents make him something rarer, a Rhineland bishop the emperor knew by name.
