Saint Cyril, the Hieromartyr and Bishop of Gortyna, served as bishop on the island of Crete for fifty years. His martyrdom is believed to have occurred either during the reign of Emperor Decius (249–251) or that of Emperor Maximian (284–305), according to different historical accounts. When brought before the governor Lucius and ordered to sacrifice to pagan gods, Saint Cyril firmly refused, proclaiming his unwavering faith in Christ. Though sentenced to be burned alive, he miraculously remained unharmed by the flames. Witnessing this divine sign, many pagans were converted to Christianity, including Lucius himself, who then released the saint.

Despite his release, Saint Cyril remained dedicated to his mission, tirelessly preaching and converting many from paganism. However, he was grieved that he had not yet suffered martyrdom for Christ. When authorities again reported his continued evangelism, the governor ordered his execution. Rejoicing at the chance to suffer for the Truth, the aged bishop—now 84 years old—willingly accepted death, laying his head beneath the sword and attaining the crown of martyrdom.
