Adversus Haereses

Against Heresies (Latin: Adversus haereses, Greek: Κατὰ αἱρέσεων), also given as Against the Heresies, is the conventional name for the work. That name for it comes from Eusebius, whose Ecclesiastical History contains many quotations from Against Heresies. The original title of the work, in Koine Greek, was Ἔλεγχος καὶ ἀνατροπὴ τῆς ψευδωνύμου γνώσεως (Elenchos kai anatropē tēs pseudōnymou gnōseōs). And so in English the work is sometimes referred to by translations of the full Greek title, such as Refutation and Overthrow of the Knowledge Falsely So-called, The Detection and Overthrow of Knowledge Falsely So-Called, Detection and Overthrow of Knowledge Falsely So-Called, The Refutation and Overthrowal of Knowledge falsely so-called, and Refutation and Overthrowal of Knowledge falsely so-called.
