Cyprian was born probably about AD 200. He converted to Christianity in about 245 and in 248 was elected Bishop of Carthage. Soon after, the Decian persecution began (in 249/250) and Cyprian went into hiding. In 251 he returned to the city. Under Valerian, he was exiled in 257 and executed in 258. The epistolary of Cyprian consists of 81 letters (16 of them by his correspondents, and 6 synodal or collective), the majority of them are from the period of 250-251, when they were the means of Cyprian`s communication with his clergy. They offer us a wide view on the organization of the Church in Carthage in the middle of the third century, her relation with the Church of Rome, on the development of the persecutions, and on the conflicts that they caused inside the Church.

Different numerations of Cyprian's letters exist, I follow the edition of Diercks in Corpus Christianorum.
