I have just posted to sarum.academia.edu/AlistairStewart a synopticon of Ignatius of Antioch and ps-Ignatius. This is a by-product of my recently appeared translation from St Vladimir’s Seminary Press, and should be self-explanatory. I hope it proves useful.
In case anyone wonders what the connection with church orders might be, note that ps-Ignatius is widely held to be the redactor of the Apostolic Constitutions. Whether or not that is the case (although the magisterial treatment of Funk in Die apostolischen Konstitutionen: eine litterar–historische Untersuchung (Rottenburg: Wilhelm Bader, 1891) has yet to be bettered, I am still slightly unconvinced), they are certainly heirs to the same tradition. Possibly the synopticon will enable us more clearly than before to see the manner in which the pseudepigrapher worked.
