Raised in piety, he worked as a stone-mason until an accident deprived him of his reason and of the power of speech. The local Turkish rulers took advantage of his condition to declare him a Muslim. For years thereafter he was employed as a shepherd until he met a monk named Cyril, who prayed fervently that he be restored to his senses. He was miraculously restored, and almost immediately was filled with the desire to repent and to live only for Christ, devoting himself to prayer, fasting and vigil. Some time later he was falsely suspected of a crime by the (Christian) people of his village, and brought before the Turkish authorities. When he was questioned, he declared 'I was born a Christian, I was brought up as a Christian, I have never denied Christ for Islam, and I never will deny Him, but will die a Christian.' For this he was brutally tortured. Many local Christians, including the village priest, feared for their own safety and urged him to deny Christ, but Nicholas only rebuked them and stood firm. After many days of torture he was finally slain by the sword. The Synaxarion tells how a thick darkness fell on the whole island of Chios. When the dismayed Turks burned the Martyr's body to be rid of this miracle, they were further dismayed when a heavenly scent rose from the flames, revealing the Saint's entry into eternal glory.
