S. Irenaeus Lugdunensis, Contra haereses liber primus

Irenaeus of Lyons (c. 130-c. 202): the first book of Against Heresies, setting out and refuting the Valentinian system and the earlier heresies, c. 180, in Greek where it survives and in the Old Latin from chapter XXII, with the editors' notes (Migne, PG 7). The facing Old Latin of chapters I-XXI and most of the chapter headings and summaries printed across the page are not yet set and are marked as such. The text was first read by volunteers through the Reading Room's volunteer page and by Gemini (a machine reader), and the Reading Room checked a sample of the Gemini columns against the page.
