All names beforeMaternus II are to be approached with considerable skepticism, as little contemporary evidence is available. Maternus was present at a council inRome in 313. The bishops between Severinus and Charentius are alsoapocryphal. Domitianus was theBishop of Maastricht (Mosa Traiectum). The given dates of office beforeGunther are also conjectural, at best.
