Sebastian succeeded in converting Tranquillinus and Martia, as well as Saint Tiburtius, the son of Chromatius, the local prefect. Another official, Nicostratus, and his wife Zoe were also converted. It has been said that Zoe had been a mute for six years; however, she made known to Sebastian her desire to be converted to Christianity. As soon as she had, her speech returned to her. Nicostratus then brought the rest of the prisoners; these 16 persons were converted by Sebastian. Chromatius and Tiburtius converted; Chromatius set all of his prisoners free from jail, resigned his position, and retired to the country in Campania. Marcus and Marcellian, after being concealed by a Christian named Castulus, were later martyred, as were Nicostratus, Zoe, and Tiburtius. Sebastian had prudently concealed his faith, but in 286 it was detected. Diocletian reproached him for his supposed betrayal, and he commanded him to be led to a field and there to be bound to a stake so that certain archers from Mauritania would shoot arrows at him. "And the archers shot at him till he was as full of arrows as an urchin is full of pricks, and thus left him there for dead." Miraculously, the arrows did not kill him. The widow of Castulus, Irene of Rome, went to retrieve his body to bury it, and discovered he was still alive. She brought him back to her house and nursed him back to health. Sebastian later stood by a staircase where the emperor was to pass and harangued Diocletian for his cruelties against Christians. This freedom of speech, and from a person whom he supposed to have been dead, greatly astonished the emperor; but recovering from his surprise, he gave orders for Sebastian to be seized and beaten to death with cudgels, and his body thrown into the common sewer. A pious lady, named Lucina, admonished by the martyr in a vision, privately removed the body and buried it in the catacombs at the entrance of the cemetery of Calixtus, where now stands the Basilica of St. Sebastian. Remains reputed to be those of Sebastian are housed in Rome in the "Basilica Apostolorum," built by Pope Damasus I in 367 on the site of the provisional tomb of Saints Peter and Paul.
