Augustine of Hippo (354 – 430 AD), in his Letter 53, wrote a list of 38 popes from Saint Peter to Siricius. The order of this list differs from the lists of Irenaeus and the Annuario Pontificio. Augustine's list claims that Linus was succeeded by Clement and Clement was succeeded by Anacletus as in the list of Eusebius, while the other two lists switch the positions of Clement and Anacletus.
