Fragments from the Lost Writings of Irenaeus

Thirty-five surviving fragments preserved by later writers from Irenaeus's lost works. Includes the famous Letter to Florinus (Fragment 2), in which Irenaeus recalls his boyhood discipleship under Polycarp — the primary textual witness for the John → Polycarp → Irenaeus apostolic chain. Fragment 3 (Letter to Victor) records his irenic intervention in the Paschal Controversy with Rome.
