(Saint) Bishop, Martyr (May 18) (4th century) An Egyptian Bishop who suffered imprisonment as a Christian under the Emperor Galerius, and who, after the Peace of the Church, assisted at the Council of Nicaea (A.D. 325). True to the Catholic Faith, he shared with Saint Athanasius his exile. And it is Saint Athanasius who relates how the Arians compassed the death of the holy Martyr, about A.D. 340.
