The Holy 20,000 Martyrs of Nicomedia: At the beginning of the fourth century the emperor Maximian (284-305) gave orders to destroy Christian churches, to burn service books, and to deprive all Christians of rights and privileges of citizenship. At this time the bishop of the city of Nicomedia was Saint Cyril, who by his preaching and life contributed to the spread of Christianity, so that many members of the emperor’s court were also secret Christians.
On the Feast of the Nativity of Christ in the year 302, when about 20,000 Christians had assembled at the cathedral in Nicomedia, the emperor sent a herald into the church. He told the Christians that soldiers were surrounding the building, and that anyone who wished to leave had to offer sacrifice to the pagan gods. Anyone who defied the emperor would perish when the soldiers set fire to the church. All those present refused to worship the idols.
As the pagans prepared to set fire to the church, Bishop Anthimus, baptized all the catechumens and communed everyone with the Holy Mysteries. All 20,000 of those praying died in the fire. Among them were the abbess Agatha and Saint Theophila who had been saved from the den of iniquity by a miracle. Bishop Anthimus, however, managed to escape the fire.
The persecution against Christians continued. Dorotheus, Mardonius, Migdonius the deacon and others were thrown into prison. Bishop Anthimus encouraged them by sending letters to them. One of the messengers, the Deacon Theophilus, was captured. They subjected him to torture, trying to learn where the bishop was hiding. The holy martyr endured everything, while revealing nothing. Then they executed him and also those whom the bishop had addressed in his letter. Though they were executed in different ways, they all showed the same courage and received their crowns from God.
For weeks, Saint Domna concealed herself within a cave and sustained herself by eating plants. When she returned to the city, she wept for a long time at the ruins of the church, regretting that she was not found worthy to die with the others. That night she went the sea shore. At that moment fishermen pulled the bodies of the martyrs Indes, Gorgonius and Peter from the water in their nets.
Saint Domna was still dressed in men’s clothing, and she helped the fishermen to draw in their nets. They left her the bodies of the martyrs. With reverence she looked after the holy relics and wept over them, especially over the body of her spiritual friend, the Martyr Indes.
After giving them an honorable burial, she did not depart from these graves so dear to her heart. Each day she burned incense before them, sprinkling them with fragrant oils. When the emperor was told of an unknown youth who offered incense at the graves of executed Christians, he gave orders to behead the youth. The Martyr Euthymius was also executed along with Domna.
