The list of Popes and dates is taken from the Annuario Pontificio, the official publication of the Holy See. The earliest part of this official list is taken from the 5th century catalogue of Popes on a wall at the ancient Basilica of St. Paul's, outside the Walls in Rome, placed there on the order of Pope St. Leo the Great (440 – 461AD). Pope Leo's list continues through his pontificate but I have limited the list to the reign of Constantine and Pope St. Sylvester I. Another earlier list is found in Bishop Eusebius' History of the Church written in the early 4th century in which Eusebius records a list of the first twelve Popes / Bishops of Rome from a list composed by St. Irenaeus in the 2nd century AD. St. Irenaeus' list agrees with Pope Leo's list with the exception of Pope Anacletus [100-112 AD] whose name is missing from Irenaeus' 2nd century list. For St. Irenaeus' 2nd century list see Church History, Bishop Eusebius, Book V, chapter VI, 1-5 [Nicene and Post Nicene Fathers, volume 1, page 221, Hendricks Publishing Company]. For the chronological list of the Popes from the Annuario Pontificio see Church History, Father John Laux, Tan Book Publishers, Inc., Appendix I**. The chronological list of Roman Emperors is for the most part adapted from Augustus to Constantine, Robert M. Grant, Westminster Press, 1970.
