They were all soldiers under one general, taken captive in the time of Licinius for their faith in Christ. They were stripped naked and cast onto a frozen lake at Sebastia in Pontus. They endured the entire night, encouraging each other to be patient. Some accounts say that their persecutors placed warm baths in their sight on the shore to entice them to renounce Christ. Finally one of their number, broken by his sufferings, apostatized and left the company. One of the guards, named Aglaius, saw in a vision thirty-nine wreaths descending from heaven onto the heads of the faithful sufferers, and was moved to declare himself a Christian. He was immediately sent to join the martyrs on the frozen lake, keeping the number of forty complete. In the morning all of them, almost dead, were cast into fire, and their remains thrown in the lake. On the third day the martyrs appeared to Peter, the local bishop, and told him to search for them in the lake. The bishop went to the lake on a dark night with his clergy, and one account says that the bones of the martyrs rose to the surface and burned there like a candle. The relics were gathered and given honorable burial.   This is the most common account. The Prologue gives a somewhat different version, in which the martyrs were made to stand, not on the frozen lake, but in the freezing waters.

"Theophylact was from the east; his native city is unknown. In Constantinople he became a close friend of Tarasius, who afterwards became Patriarch of Constantinople (see Feb. 25). Theophylact was made Bishop of Nicomedia. After the death of Saint Tarasius, his successor Nicephorus (see June 2) called together a number of Bishops to help him in fighting the iconoclasm of Emperor Leo the Armenian, who reigned from 813 to 820. Among them was Euthymius, Bishop of Sardis (celebrated Dec. 26), who had attended the holy Seventh Ecumenical Council in 787 — he was exiled three times for the sake of the holy icons, and for defying the Emperor Theophilus' command to renounce the veneration of the icons, was scourged from head to foot until his whole body was one great wound, from which he died eight days later, about the year 830; Joseph of Thessalonica (see July 14); Michael of Synnada (see May 23); Emilian, Bishop of Cyzicus (see Aug. 8); and Saint Theophylact, who boldly rebuked Leo to his face, telling him that because he despised the long-suffering of God, utter destruction was about to overtake him, and there would be none to deliver him. For this, Theophylact was exiled to the fortress of Strobilus in Karia of Asia Minor, where after 30 years of imprisonment and hardship, he gave up his holy soul about the year 845. Leo the Armenian, according to the Saint's prophecy, was slain in church on the eve of our Lord's Nativity, in 820." (Great Horologion)

These seven holy Bishops give a vivid picture of the dangers endured by those who traveled to proclaim the Gospel of Christ in the early centuries of the Church. All seven were sent as missionary bishops to Cherson on the Black Sea, and all seven died there as Martyrs. Hermon, Bishop of Jerusalem, first sent Ephraim and Basileus; Basileus raised the son of the prince of Cherson to life, after which many believed and were baptized. The unbelievers, though, bound him by the feet and dragged him through the streets until he died. Ephraim was beheaded when he refused to make sacrifice to the idols. Eugenios, Agathodoros, and Elpidios were then sent by the Bishop of Jerusalem; they were beaten to death with rods and stones. Aetherius was sent during the reign of Constantine the Great, and was able to govern the Church in freedom and peace, and to build a church in Cherson. Capito, the last to be sent, brought the Gospel to the fierce Scythians. To prove the power of his God, they asked him to go into a burning furnace, saying that if he was not consumed, they would believe. Putting all his trust in God, the holy Bishop vested himself, made the sign of the Cross, and entered the furnace. He stood in the flames, fervently praying, for an hour, and came out untouched. The spectators cried out 'There is one God, the great and powerful God of the Christians, who keeps His servant safe in the burning furnace!', and all those in the town and the surrounding countryside were baptized. This miracle was spoken of at the Council of Nicea (325). Later, Scythian unbelievers captured Capito and drowned him in the River Dnieper.   The Prologue says that Aetherios ended his life in peace; the Great Horologion, that he was drowned. All these holy missionaries labored around the beginning of the fourth century.

They were taken captive when Amorion in Phrygia fell to the Muslims in 838, during the reign of Emperor Theophilus. Many of them were officers, and because of their status and reputation, their captors, rather than kill them, attempted to convert them to Islam. The forty-two were kept in a miserable dungeon in Syria, where they were alternately promised the highest honors and privileges if they would convert and threatened with the most horrible consequences if they refused. This continued for seven full years, but none would deny his faith in Christ. Finally, unable to shake their faith, their captors beheaded them all in 845.

St Mark was a disciple of St John Chrysostom, tonsured a monk at the age of forty by St John himself. He then withdrew to the Nitrian desert and lived for sixty years as a hermit, devoting himself to fasting, prayer, and writing spiritual discourses.   Saint Mark knew all the Holy Scriptures by heart. His compassion was so great that he wept at the distress of any of God's creatures: once he wept for the blind pup of a hyena, and the pup received its sight. Though he lived alone in the desert, it is said that he received Communion from an angel.   The holy and scholarly Patriarch Photios held his writings in the highest esteem, and at one time there was a saying, 'sell all that you have, and buy Mark.' Some of these beautiful and profound writings may be read in English in the first volume of the Philokalia.
