Overview
- San Agricio, fourth-century bishop of Trier, is the principal commemoration on January 13 in the Catholic santoral.
- A historically attested detail places Agricio at the Council of Arles in 314, where he signed the acts as bishop and was noted with primacy in Gaul and Germania.
- A ninth-century local tradition claims Agricio once held the patriarchate of Antioch, a title presented as lore rather than established fact.
- Tradition also holds that Empress Helena sent notable relics to Trier, including a nail from the cross, the Last Supper knife, relics of Matthias, Lazarus and Martha, and the Holy Tunic.
- St. Hilary of Poitiers is also remembered today as a bishop, writer, and Doctor of the Church, with accounts noting his conversion as an adult and exile to Phrygia under Constantius II; additional commemorations include St. Peter priest and martyr, St. Godofredo of Ilbenstad, St. Justa of Huy, St. Kentigern, and St. Remigius of Reims.
