Thascius Caecilius Cyprianus, illustrious as a pagan rhetorician in Carthage, embraced the true faith in the year 246 and was soon thereafter consecrated priest and bishop of that city (248). He was an energetic shepherd of souls and a prolific writer. He defended the unity of the Church against schismatic movements in Africa and Italy, and greatly influenced the shaping of Church discipline relative to reinstating Christians who had apostatized. He fled during the Decian persecution but guided the Church by means of letters. During the Valerian persecution (258) he was beheaded. He suffered martyrdom in the presence of his flock, after giving the executioner twenty-five pieces of gold. St. Jerome says of him: "It is superfluous to speak of his greatness, for his works are more luminous than the sun." Cyprian ranks as an important Church Father, one whose writings are universally respected and often read in the Divine Office. His principal works are: On the Unity of the Church; On Apostates; a collection of Letters; The Lord's Prayer; On the Value of Patience. http://www.catholicculture.org/culture/liturgicalyear/calendar/day.cfm?date=2015-09-16
A few days after St Cyprian's execution the gorernor who ordered that execution also died. We don't know where he is today but we do know where St Cyprian is today.
