“ St. Athanasius, who came as an exile to Trier in 335 or 336, speaks of the large numbers of faithful whom he found there and the number of churches in course of erection. The famous relics of Trier (Holy Coat, Nail of the True Cross, the body of St. Matthias the Apostle) are said by local tradition to have been brought thither by Agricius. The schools of Trier became famous under Agricius. Lactantius taught in them, and St. Maximin and St. Paulinus, later successors to the See of Trier, came from Aquitaine to study there. Agricius died after an active episcopate of twenty years. ”
