Born in Naples of a pagan father and a Christian mother, he was an officer in the Roman army in Naples. He was not baptised, although his mother, unbeknown to his father, had instructed him in the Christian faith. Once, when he was setting off with his company to war, his mother advised him, if he were in trouble, to make the sign of the Cross and call on Christ to help him. And so, when Nikon's company was surrounded during the battle and close to final exter-mination, Nikon made the sign of the Cross and began to call upon Christ. At that moment he was filled with exceptional strength and rushed upon his opponents, killing some and putting the others to flight. Returning home, Nikon could not stop exclaming in wonder: `Great is the God of the Christians!' After he had brought joy to his mother with his report of the victory by the aid of Christ's Cross, he set sail in secret for Asia, where the Bishop of Cyzicus, Theodosius, baptised him. After his baptism, he shut himself up in a monastery and devoted himself to study and to asceticism. However, Bishop Theodosius had a vision before his death, in which he was told to consecrate Nikon as his successor. The aged Theodosius summoned Nikon immediately and ordained him deacon, and then priest and bishop. By divine providence Nikon came soon after this to Neapolis, where he found his mother still alive. On her death, he went to Sicily with nine disciples, one-time comrades in battle, and there devoted himself to preaching the Gospel. There was a terrible persecution of Christians at that time, and Prince Ouintianus seized Nikon and his companions and gave them over to great torture. One hundred and ninety of his disciples and friends were slain. The tor-turer tied Nikon to the tails of horses, threw him from a high cliff into a ravine, beat him and flayed him, yet Nikon survived all these tortures. He was finally slain with the sword and his body was aban-doned in a field for the birds to eat, but a shepherd boy, possessed by a raging evil spirit, fell on the dead body of Christ's martyr, took hold of it, and was immediately healed. He spread the news about Nikon's body, and Christians came and buried it. St Nikon suffered and went to the Lord in the reign of the Emperor Decius.
