36 CHAPTER II THE WRITTINGS OF EUSEBIUS was brought down to the vicennalia of Constantine,—that is, to the year 325,—but the Chronicle is referred to as an already published work in the Eclogæ propheticæ (I. 1), and in the Præparatio Evang. (X. 9), both of which were written before 313. We may conclude, then, that a first edition of the work was published during, or more probably before, the great persecution, and that a second and revised edition was issued probably in 325, or soon thereafter. For further particulars in regard to the Chronicle see especially the article of Salmon already referred to. The work has been issued separately a great many times. We may refer here to the edition of Scaliger, which was published in 1606 (2d ed. 1658), in which he attempted to restore the Greek text from the fragments of Syncellus and other ancient writers, and to the new edition of Mai, which was printed in 1833 in his Scriptorum veterum nova collectio, Tom. VIII., and reprinted by Migne, Eusebii Opera, I. 99–598. The best and most recent edition, however, and the one which supersedes all earlier editions, is that of Alfred Schoene, in two volumes: Berlin, 1875 and 1866. Ecclesiastical History (ἐκκλησιαστικὴ ἱστορία). For a discussion of this work see below, p. 45 sq. Life of Constantine (εἰς τὸν βίον τοῦ μακαρίου Κωνσταντίνου τοῦ βασιλέως). For particulars in regard to this work, see the prolegomena of Dr. Richardson, on pp. 466–469 sq., of this volume. II. APOLOGETIC WORKS. Against Hierocles (πρὸς τοὺς ὑπὲρ ᾽Απολλωνίου τοῦ τυανέως ῾Ιεροκλέους λόγους, as Photius calls it in his Bibl. 39). Hierocles was governor of Bithynia during the early years of the Diocletian persecution, and afterwards governor of Egypt. In both places he treated the Christians with great severity, carrying out the edicts of the emperors to the fullest extent, and even making use of the most terrible and loathsome forms of persecution (see Lactantius, De Mort. Pers. 16, and Eusebius, Mart. Pal. 5, Cureton’s ed. p. 18). He was at the same time a Neo-Platonic philosopher, exceedingly well versed in the Scriptures and doctrines of the Christians. In a work against the Christians entitled λόγος φιλαλήθης πρὸς τοὺς χριστιανούς, he brought forward many scriptural difficulties and alleged contradictions, and also instituted a comparison between Christ and Apollonius of Tyana, with the intention of disparaging the former. Eusebius feels called upon to answer the work, but confines himself entirely to that part of it which concerned Christ and Apollonius, leaving to some future time a refutation of the remainder of the work, which indeed, he says, as a mere reproduction of the arguments of Celsus, had been already virtually answered by Origen (see chap. 1). Eusebius admits that Apollonius was a good man, but refuses to concede that he was anything more, or that he can be compared with Christ. He endeavors to show that the account of Apollonius given by Philostratus is full of contradictions and does not rest upon trustworthy evidence. The tone of the book is mild, and the arguments in the main sound and well presented. It is impossible to fix the date of the work with any degree of certainty. Valesius assigns it to the later years of the persecution, when Eusebius visited Egypt; Stein says that it may have been written about 312 or 313, or even earlier; while Lightfoot simply remarks, “it was probably one of the earliest works of Eusebius.” There is no ground for putting it at one time rather than another except the intrinsic probability that it was written soon after the work to which it was intended to be a reply. In fact, had a number of years elapsed after the publication of Hierocles’ attack, Eusebius would doubtless, if writing against it at all, have given a fuller and more complete refutation of it, such as he suggests in the first chapter that he may yet give. The work of Hierocles, meanwhile, must have been written at any rate some time before the end of the persecution, for it is mentioned in Lactantius’ Div. Inst. V. 2. Eusebius’ work has been published by Gaisford: Eusebii Pamph. contra Hieroclem et Marcellum libri, Oxon. 1852; and also in various editions of the works of Philostratus. Migne, Opera IV. 795 sq., reprints it from Olearius’ edition of Philostratus’ works (Lips. 1709). Against Porphyry (κατὰ Πορφυρίον). Porphyry, the celebrated Neo-Platonic philosopher, regarded by the early Fathers as the bitterest and most dangerous enemy of the Church, wrote toward the end of the third century a work against Christianity in fifteen books, which was looked upon as the most powerful attack that had ever been made, and which called forth refutations from some of the greatest Fathers of the age: from Methodius of Tyre, Eusebius of Cæsarea, and Apollinaris of Laodicea; and even as late as the end of the fourth or beginning of the fifth century the historian Philostorgius thought it necessary to write another reply to it (see his H. E. X. 10). Porphyry’s work is no longer extant, but the fragments of it which remain show us that it was both learned and skillful. He made much of the alleged contra dictions in the Gospel records, and suggested difficulties which are still favorite weapons in the hands of skeptics. Like the work of Porphyry, and all the other refutations of it, the Apology of Eusebius has entirely perished. It is mentioned by Jerome (de vir. ill. 81 and Ep. ad Magnum, §3, Migne’s ed. Ep. 70), by Socrates
