Maris was a bishop of Chalcedon in the 4th century and a prominent backer of Arianism. He is also notable for confronting the anti-Christian emperor Julian the Apostate in 362 after going blind - in reply to Julian telling him "Thy Galilean God will not heal thy sight." He replied "I thank God for depriving me of the power of beholding thy face."
