Cyrus, a physician of Alexandria, who by the opportunities which his profession gave him, had converted many sick persons to the faith; and John, an Arabian, hearing that a lady called Athanasia, and her three daughters, of which the eldest was only fifteen years of age, suffered torments for the name of Christ at Canope in Egypt, went thither to encourage them. They were apprehended themselves, and cruelly beaten: their sides were burned with torches, and salt and vinegar poured into their wounds in the presence of Athanasia and her daughters, who were also tortured after them. At length the four ladies, and a few days after, Cyrus and John, were beheaded, the two latter on this day. The Syrians, Egyptians, Greeks, and Latins, honour their memory. See their acts by Saint Sophronius, commended in the seventh general council, and published with remarks by Bollandus.
