In the time of the Emperor Hadrian (117-138), a pagan called Catallus bought Hesperus, his wife Zoe and their sons Cyriac and Theodulus as slaves. Being convinced Christians, they refused to eat anything that had been sacrificed to idols, but threw all that had been thus offered to the dogs, and themselves went hungry. Catallus, discovering this, became very angry and began to torture his slaves cruelly. He first tortured the children, but they remained unfaltering in the Faith and sought yet harsher tortures. At last all four of them were cast into a burning furnace where, after prayers of thanksgiving, they gave their spirits into the Lord's hands. Their bodies remained whole and untouched by the fire.
They were sons of the great Prince Vladimir, Baptiser of the Russian people. Until his baptism, Vladimir had many wives, and children by them. Boris and Gleb were brothers of one mother. Before his death in 1015, Vladimir divided the Kingdom among all his sons. But Svyatopolk, his eldest son and Prince of Kiev, desired to take the parts that were set aside for Boris and Gleb, so he sent men to kill Boris in one place and Gleb in another. Both brothers were deeply devout and pleasing to God in all things, and they met death with prayer and the lifting up of their hearts to Him. Their bodies remained uncorrupt and fragrant, and were buried in the town of Vishgorod, where to this day blessed strength flows forth from them to heal men of divers ills and sufferings.
He was born and educated as a pagan and was baptized under the influence of his uncle Bojan and his sister. At baptism, he was given the name Michael. Patriarch Photius sent him priests who gradually baptized all the Bulgarian people. Many Bulgarian noblemen opposed this new Faith but the new Faith conquered and the Cross glistened on many churches built by the devout Tsar Michael. The Faith among the Bulgarians, as among the Serbs, was especially established by the Five Followers, the disciples of St. Cyril and St. Methodius, who preached to the people the knowledge of Christ in the vernacular: the Slavonic language. In his old age Michael retreated to a monastery and was tonsured a monk. When his son Vladimir began to destroy his father's work and to exterminate Christianity, Michael again donned his military uniform, girded himself with a sword, ousted Vladimir from the throne and installed Simeon, his younger son, as Tsar. After that, he again clothed himself in the monastic habit and retreated in silence where, in mortification and prayer, he completed his earthly life "in the good faith; in the correct confession of our Lord Jesus Christ; great, honourable and devout," and took up habitation in the heavenly life on May 2, 906 A.D.
