 From the "Gesta" the narrative passed unchallenged into numerous medieval works.Later criticism has detected many contradictions and inaccuracies in these ancient records, and it is almost universally believed at present that, with few exceptions, the first Christian missionaries came to Gaul, to which Trier then belonged, not earlier than about 250.Following Hontheim, Calmet and others, the Bollandists, with Marx, Aloys Lütolf, and other historians refer these bishops of Trier to a period following 250, though not all of them consider this as fully established.
