IT is a remarkable fact, and much to be regretted, that none of the works of St Irenæus, the greatest theologian of the second century, have come down to us in the language in which they were written. Of his chief work, the five books Against Heresies, we have a very early Latin translation, and a few fragments of the original Greek preserved through quotation by other writers. The work now before us, The Demonstration of the Apostolic Preaching, has recently been found in an Armenian translation, and no portion of it seems to have survived in any other language.
