The seven genuine epistles of Ignatius (all of which are mentioned by Eusebius in this chapter) fall into two groups, four having been written from one place and three from another. The first four—to the Ephesians, Magnesians, Trallians, and Romans—were written from Smyrna, while Ignatius was on his way to Rome, as we can learn from notices in the epistles themselves, and as is stated below by Eusebius, who probably took his information from the statements of the epistles, as we take ours. Ephesus, Magnesia, and Tralles lay to the south of Smyrna, on one of the great highways of Asia Minor. But Ignatius was taken by a road which lay further north, passing through Philadelphia and Sardis (see Lightfoot, I. 33 sq.). and thus did not visit the three cities to which he now sends epistles from Smyrna. The four epistles written from Smyrna contain no indication of the chronological order in which they were written, and whether Eusebius in his enumeration followed the manuscript of the epistles which he used (our present mss. give an entirely different order, which is not at all chronological and does not even keep the two groups distinct), or whether he exercised his own judgment, we do not know.
