Reticius was a 4th-century Gallo-Roman bishop who led the see of Autun from approximately 310 until 334. As a prominent figure during the reign of Constantine the Great, he acted as a representative for the emperor at significant ecclesiastical gatherings, including the Synods of Rome and Arles. These missions were intended to address the Donatist controversy. He is recognized as the first historically documented bishop of his diocese and is celebrated for his contributions to early Christian literature.
