Possible Examples of Later Authors Reusing Original Treatises by Irenaeus

[Secret Alias]

As many of you know, I think that early Christian works originally written by one author were continually recycled. A clear example is the use of a gospel harmony in Adversus Marcionem. What was likely originally written by Justin or one of his circle was reworked as a work centered around Luke by Irenaeus and then was passed on (and passed off) as a work of Tertullian. Another explicit example is Tertullian's Against the Valentinians deriving from the material on the Valentinians in Adversus Haereses. I can't count the number of examples but here's another from 'Cassian the Roman' and his commentary on the Apocalypse of John:

His own 'Book', namely Codex 573, contains a text whose title is ascribed to Irenaeus, although it is currently attributed to Hippolytus ('On the Blessings of Jacob'). https://books.google.com/books?id=Eb_3C ... us&f=false

So Cassian understood that the Blessings of Jacob was written by Irenaeus.
