Agricius of Trier

History Little else is known about Agricius. There are stories about him, but these are based in part on Altmann's dubious Vita Helenae of about 850. in Syria.

An 11th-century tradition states that he had been a priest of Antioch, and that he was moved to the See of Trier by Pope Sylvester I at the request of the Empress Helena. He was present at the Council of Arles in 314, where he signed the acts immediately after the presiding bishop of that diocese. This indicated that, at least in the fourth century, Trier laid claim to the primacy of Gaul and Germany, a claim his successor Saint Maximin reinforced. This story seems to have developed in order to promote the primacy of Trier over other sees in Gaul and Germany. "Saint Agritius laboured zealously and successfully during twenty years at the conversion of Gaul and of Western Germany."

Saint 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 the course of being built. The famous relics of Trier - the above-named "Heiliger Rock", the Nail of the True Cross, and the body of Matthias the Apostle - are all said to have been brought there by Agricius.
