Tradition and attributed to Hippolytus; at present this attribution is hotly contested. Differences in style and theology lead some scholars to conclude that some of the works attributed to Hippolytus actually derive from a second author. Two small but potentially important works, On the Twelve Apostles of Christ and On the Seventy Apostles of Christ, are often neglected because the manuscripts were lost during most of the church age and then found in Greece in the 19th century. . The two are included in an appendix to the works of Hippolytus in the voluminous collection of Early Church Fathers. The work on the 70 apostles is noteworthy as a (potentially) early source. A consensus of scholarship agrees on a core of authentic texts composed by the second-third century writer Hippolytus, regardless of disputes concerning his community, or the exact dates of his biography: these are the biblical commentaries, including On Daniel, On David and Goliath, On the Song of Songs (partially extant), On the Blessings of Isaac and Jacob, and On the Antichrist. These form a sound basis for exploring and understanding his theology and biblical doctrines. Eschatology Hippolytus is an important figure in the development of Christian eschatology. In his biblical compendium and topical study On Christ and the Antichrist and in his Commentary on the Prophet Daniel Hippolytus gave his interpretation of the second advent of Christ. With the onset of persecutions during the reign of Septimius Severus, many early Christian writers treated topics of apocalyptic eschatology. On Christ and the Antichrist is one of the earliest works. It is thought Hippolytus was generally influenced by Irenaeus. However, unlike Irenaeus, Hippolytus focuses on the meaning of prophecy for the Church in his own time. Of the dogmatic works, On Christ and the Antichrist survives in a complete state and was probably written about 202. Hippolytus follows the long-established usage in interpreting Daniel's seventy prophetic weeks to be weeks of literal years. Hippolytus gave an explanation of Daniel's paralleling prophecies of chapters 2 and 7, which he, as with the other fathers, specifically relates to the Babylonians, Persians, Greeks, and Romans. His interpretation of events and their significance is Christological. Hippolytus did not subscribe to the belief that the Second Coming was imminent. In his commentary on Daniel he criticizes those who predict the Second Coming in the near future, and then says that six thousand years must pass
