Aaron of Auxerre

Holy Hierarch Aaron of Auxerre was a monk, then abbot of Saint-⁠Marien at Auxerre and bishop of Auxerre at the beginning of the 9th century (perhaps between 794 and 807); he reposed in 813 and is called "blessed". His origin is not known precisely; he may have been from a rich family. He succeeded Bishop Maurinus in the see, the date being unknown.

He gave the cathedral of Saint Stephen at Auxerre four bells and had a baldachin of gold and silver made. According to the "Deeds of the Bishops of Auxerre", he was part of the group of lords and great prelates who accompanied Charlemagne to Rome, to Pope Leo III, and took part in the coronation in the year 800. His relics are venerated in the church of Saint-⁠Germain at Auxerre, where his day is celebrated on 28 September. He is honored as a saint of the undivided Church.
