Reverianus was a 3rd-century bishop from Italy who served as a missionary to the Gallic Aedui people. Sent by Pope Felix I, he became known as the apostle of the Morvan region. During the reign of Emperor Aurelian, his preaching led to his execution alongside his companion, Paulus of Autun, and ten other followers. He is remembered as a hieromartyr and is venerated in the Roman Catholic Church.
