Biography
Leontius of Trier

About Leontius of Trier
Leontius, also called Legontius, belongs to Trier’s early succession of bishops. The diocesan list places him between Mauritius and Severus.
His surviving record is sparse. The Bollandist review rejects an unsupported Aquitanian ancestry and cautions against later writers’ expanded accounts of his achievements. It records several forms of his name and the short notices by which he was remembered as a bishop and confessor. Such notices preserve his veneration without providing a continuous biography.
He has been identified with the Leontius honored in Pope Leo’s correspondence, though that identification remains a scholarly conclusion rather than an explicit statement of his see in the letter.
Leo praises a bishop named Leontius for his seniority and reputation, directing that councils require his consent while preserving the rights of the metropolitan bishops. The letter itself does not identify him as bishop of Trier.
Later evidence is clearer about devotion than about his life. The tenth-century Egbert Psalter includes him among Trier’s saintly bishops. Medieval searches for his remains initially failed; relics later attributed to him were taken to Schaffhausen. The sarcophagus subsequently identified as his at Saint-Paulin proved problematic: a 1960 excavation revealed an inscription for a young man named Auspicius. Heyen therefore rejects that tomb identification.
Leontius is commemorated on February 19. The uncertainties surrounding his remains should not be turned into certainty about his burial or death place.
