In my Ignatius I wrote that, since Hadrian arrived in Rome in 135, Ignatius might have been writing in 134. This is in the context of my suggestion that Ignatius travelled with Hadrian on his journey to Rome.
In revising my paper from the Oxford conference, dealing with Ignatius’ “docetic” opponents, I now realize that Hadrian was actually in Rome already in 134; I think I was confused because Hadrian’s salutatio imperatoria after the Bar Kosiba revolt took place in August of 135. In other words, my date for Ignatius’ correspondence needs to be revised by a year (or possibly two, as there is some obscurity over the date and direction of Hadrian’s last journey.)
Nonetheless, I continue to hold a Hadrianic date for Ignatius’ correspondence, and to read it in the light of the rupture brought about between Jewish Christ-believers and other Jews by the revolt. This is better than the traditional Trajanic date, and does not present the problems caused by seeing the whole correspondence as a forgery.
