Saint Hippolytus of Rome (c. 170-c. 236) was one of the most prolific writers of the early Church. Hippolytus was born during the second half of the 2nd century, probably in Rome. Photius describes him in his Bibliotheca (cod. 121) as a disciple of Irenaeus, who was said to be a disciple of Polycarp, and from the context of this passage it is supposed that he suggested that Hippolytus himself so styled himself. However, this assertion is doubtful. He came into conflict with the Popes of his time and for some time headed a separate group. For that reason he is sometimes considered the first Antipope. However he died in 235 or 236 reconciled to the Church and as a martyr.
