thecae Bodleianae codices recognovit: quaedam et ipse ad mss. Bibliothecae Regiae codices exegi. Haec excipient eorum Praefationes, Prolegomena, notae et observationes, qui novas Irenaei editiones hactenus publicarunt, vel illustrarunt; ut sic uno volumine comprehensum, minorique sumptu studiosi nanciscantur, quod antea nonnisi pluribus et majori impensa comparare sibi poterant. Et quidem quod ad notas et observationes attinet; Billii, Frontonis Ducaei et Feuardentii integras denuo edi curavi, quamvis plura jam ex iis decerpsissem, meisque inseruissem; ratus gratum me facturum lectoribus, si totum exhibeam, cujus partes antea legerint. Ex Gallasio paucissimas selegi, cum pleraeque nihil nisi vanas inficetasque declamationes contineant. Ex Grabio plures, eas videlicet quas catholicae aures ferre possint. Feuardentii notas non omnibus placere, Protestantibus vero plurimum displicere probe novi. Quin tamen pro tempore eruditae sint, virque pius ac doctus de Irenaeo, totaque Ecclesia catholica optime meritus fuerit, nemo absque injuria negare potest. Saepe quidem ab argumento longius discedit, et in heterodoxos acerbiori quam par esset stylo excurrit; sed id zelo catholicae fidei, et tempori, quo ferventibus controversiis bellisque civilibus, Calvinistae Catholicos perpetuis conviciis et calumniis incessebant, condonandum. Quisquis ministrorum illius temporis scripta legerit, et quam inverecunde Catholicis calumniam facerent ac clarissimis quibusque Patrum testimoniis vim inferrent, expenderit, Feuardentium facile excusabit. Si quae vero hujus argumenta intempestiva jam esse videantur; non ipsius, sed adversariorum culpa est, qui parum sibi constantes, mutata identidem velificatione retrocedere, pluraque male constituto systemati vel addere, vel demere, pro temporum et argumentorum ratione, coacti sunt. Acrius nec aequius doctissimum hominem reprehendunt recentiores quidam, quod adulterina scripta non pauca, ut vera allegaverit, eosque Libros et Tractatus Patribus pluribus attribuerit, qui jam supposititii esse agnoscuntur. Sed communis hic fuit error illorum temporum: nondum quippe satis eliquata veritate reque ad severiores criticae regulas pensitata, id bona fide citabatur, de quo nullus esse videbatur suspicandi locus. Qui Magdeburgenses ipsos, famosumque illum apud Protestantes criticum Andream Rivetum examinaverit, si non iisdem, in aliis tamen gravius lapsos, nec artis criticae peritiores fuisse illico deprehendet. Sed tandem si quid peccaverit Feuardentius, gravius, mea quidem sententia, peccat, qui culpam confitenti et quamprimum emendanti iterum objicere non veretur. Dum primam Irenaei sui editionem adornaret, scribens in libri tertii cap. 33, nunc 22, inter varia quae congerit Patrum testimonia, unum velut ex Cyrillo Alexandrino lib. VI in Joann., cap. 15, addidit: quod Cyrilli non est, sed Jodoci Clichtovei, qui quatuor Commentariorum suorum libros Cyrillinis interseruit. Errore statim agnito, hunc emendare festinavit vir bonus; sed cum folium jam per typographos excusum esset, nullum aliud supererat remedium, nisi ut qua ratione corrigendus esset, lectores tempestive moneret in erratorum indice; quod et fecit. Cum autem Franciscus Suarez, haud lecto illo indice, Feuardentium acerbius perstrinxisset, digne pro incogitantia castigatus est in editione Coloniensi anni 1596. Ecce tamen, recentior quidam criticus, ne lectis quidem seu memorato indice, seu notis in citata editione additis, in sola Suarezii, aut Theophili Rainaudi fide, erratum bis correctum et emendatum illi adhuc impingit. Quibus jam verbis exciperet Feuardentius, si viveret, accuratum illum censorem, qui quos auctores redarguit, ne segni quidem manu evolvere dignatur? Ut ut est, Feuardentii notas et observationes, quales in novissimis Irenaei editionibus prodierunt, tales iterum edi curavi; ita tamen ut omnia ejusdem (quod et idem de aliis dici velim) dicta et allegata praestare nolim. Neque enim a me exspectandum fuit, ut omnia quae profert auctorum testimonia expenderem, ac si quis in iis citandis error obrepserit, indicarem: laboris id immensi fuisset; quem si suscepissem, non jam ipsas Feuardentii notas, sed novas in Feuardentium observationes, nullo aut exiguo fructu dedissem. Cum autem tum Feuardentius, tum alii observationes suas ad veterem capitum sectionem, quam sequebantur, accommodarint; sic accommodatas, ne qua confusio suboriretur, reliqui: novae duntaxat editionis capita et paginas ad marginem indicavi.
Bodleian Library; some I myself also examined against the manuscript codices of the Royal Library. These will be followed by the Prefaces, Prolegomena, notes, and observations of those who have hitherto published or illustrated new editions of Irenaeus, so that students may thus obtain comprised in a single volume and at smaller expense what previously they could procure for themselves only in several volumes and at greater cost. And indeed, so far as concerns the notes and observations, I have taken care that those of Billy, Fronton du Duc, and Feuardent should be published anew in their entirety, although I had already plucked out several things from them and inserted them into my own, judging that I would do a welcome service to readers if I presented the whole of that of which they had previously read parts. From des Gallars I have selected very few, since most contain nothing but vain and witless declamations. From Grabe more, namely those which Catholic ears can bear. That the notes of Feuardent do not please everyone, and indeed displease Protestants very much, I well know. Yet that they are learned for their time, and that the pious and learned man deserved exceedingly well of Irenaeus and of the whole Catholic Church, no one can deny without injustice. Often indeed he departs rather far from the subject, and runs out against the heterodox in a sharper style than was fitting; but this must be pardoned to his zeal for the Catholic faith, and to the time when, amid raging controversies and civil wars, the Calvinists assailed Catholics with perpetual revilings and calumnies. Whoever reads the writings of the ministers of that time, and weighs how shamelessly they brought calumny against Catholics and did violence to all the clearest testimonies of the Fathers, will easily excuse Feuardent. If, however, any of his arguments now seem unseasonable, it is the fault not of himself, but of his adversaries, who, little consistent with themselves, shifting their tack again and again, have been forced to retreat and either to add several things to, or take them away from, an ill-constructed system, according to the exigencies of times and arguments. More sharply, though not more fairly, certain more recent writers reprove the most learned man because he alleged not a few spurious writings as genuine, and attributed to several Fathers those Books and Treatises which are now recognized to be supposititious. But this was the common error of those times: for since the truth had not yet been sufficiently strained out and the matter weighed according to the stricter rules of criticism, that was cited in good faith concerning which there seemed to be no room for suspicion. Whoever examines the Magdeburg Centuriators themselves, and that famous critic among the Protestants, André Rivet, will straightway discover that they slipped more gravely, if not in the same things, yet in others, and were no more skilled in the art of criticism. Yet after all, if Feuardent sinned in anything, he sins more gravely, in my judgement at least, who does not shrink from casting up again a fault against one who confesses it and emends it as soon as possible. While he was preparing his first edition of Irenaeus, writing on chapter 33, now 22, of the third book, among various testimonies of the Fathers which he heaps together, he added one as if from Cyril of Alexandria, Book VI on John, Chapter 15, which is not Cyril's, but Josse Clichtove's, who inserted four books of his own Commentaries among those of Cyril. Recognizing the error immediately, the good man hastened to emend it; but since the sheet had already been printed off by the printers, no other remedy remained save that he should seasonably warn the readers in the index of errata in what way it was to be corrected; which he also did. When, however, Francisco Suárez, not having read that index, had censured Feuardent rather sharply, he was worthily chastised for his thoughtlessness in the Cologne edition of the year 1596. Yet behold, a certain more recent critic, without having read either the aforesaid index or the notes added in the cited edition, on the sole credit of Suárez or of Théophile Raynaud, still fastens upon him an error twice corrected and emended. With what words would Feuardent now receive, if he were alive, that accurate censor who does not deign to turn over even with a sluggish hand the authors whom he refutes? However that may be, the notes and observations of Feuardent, such as they came forth in the latest editions of Irenaeus, I have taken care to have published again just so; yet in such a way that I would not wish to vouch for all his sayings and allegations (which I would wish to be said of the others as well). For it was not to be expected of me that I should weigh all the testimonies of authors which he brings forward, and indicate if any error crept in while citing them: that would have been a work of immense labour, and had I undertaken it, I would have given not now the notes of Feuardent himself, but new observations upon Feuardent, with no or slight fruit. Since, moreover, both Feuardent and the others accommodated their observations to the old division of chapters which they followed, I have left them thus accommodated, lest any confusion should arise: I have only indicated in the margin the chapters and pages of the new edition.
