original Greek, through means of copious quotations made by Hippolytus and Epiphanius. 312 The text, both Latin and Greek, is often most uncertain. Only three mss. of the work Against Heresies are at present known to exist. Others, however, were used in the earliest printed editions put forth by Erasmus. And as these codices were more ancient than any now available, it is greatly to be regretted that they have disappeared or perished. One of our difficulties throughout, has been to fix the readings we should adopt, especially in the first book. Varieties of reading, actual or conjectural, have been noted only when some point of special importance seemed to be involved. After the text has been settled, according to the best judgment which can be formed, the work of translation remains; and that is, in this case, a matter of no small difficulty. Irenæus, even in the original Greek, is often a very obscure writer. At times he expresses himself with remarkable clearness and terseness; but, upon the whole, his style is very in- volved and prolix. And the Latin version adds to these difficulties of the original, by being itself of the most barbarous character. In fact, it is often necessary to make a conjectural re- translation of it into Greek, in order to obtain some inkling of what the author wrote. Dodwell supposes this Latin version to have been made about the end of the fourth century; but as Tertullian seems to have used it, we must rather place it in the beginning of the third. Its author is unknown, but he was certainly little qualified for his task. We have endeavoured to give as close and accurate a translation of the work as possible, but there are not a few passages in which a guess can only be made as to the probable meaning. Irenæus had manifestly taken great pains to make himself acquainted with the various heretical systems which he describes. His mode of exposing and refuting these is generally very effective. It is plain that he possessed a good share of learning, and that he had a firm grasp of the doctrines of Scripture. Not unfrequently he indulges in a kind of sarcastic hu- mour, while inveighing against the folly and impiety of the heretics. But at times he gives expression to very strange opinions. He is, for example, quite peculiar in imagining that our Lord lived to be an old man, and that His public ministry embraced at least ten years. But though, on these and some other points, the judgment of Irenæus is clearly at fault, his work contains a vast deal of sound and valuable exposition of Scripture, in opposition to the fanciful systems of interpretation which prevailed in his day. We possess only very scanty accounts of the personal history of Irenæus. It has been generally supposed that he was a native of Smyrna, or some neighbouring city, in Asia Minor. Harvey, however, thinks that he was probably born in Syria, and removed in boyhood to Smyrna. He himself tells us (iii. 3, 4) that he was in early youth acquainted with Polycarp, the illustrious bishop of that city. A sort of clue is thus furnished as to the date of his birth. Dodwell supposes that he was born so early as a.d. 97, but this is clearly a mistake; and the general date assigned to his birth is somewhere between a.d. 120 and a.d. 140. 838 Introductory Note to Irenæus Against Heresies
