Frodulphe de Barjon was a 7th-century French abbot and a dedicated disciple of Saint Mederic. Born in Autun, he was raised as an oblate at the Abbey of Saint Martin, where he focused on prayer and penance. He accompanied his mentor on a long pilgrimage to the tomb of Saint Denis in Paris, eventually returning to Burgundy to lead the monastery of Saint Martin. Following a Saracen raid on Autun in 725, he chose to live as a hermit in Barjon, where he spent his final years.
