Son of Saint Rufinus. Priest. Imprisoned, tortured and martyred in the persecutions of Maximinus with several fellow Christians, including Saint Placidus and Saint Eutychius, but most of whose names have not come down to us. While in prison, he ministered to other prisoners, and converted some who were pagans.
