...is set forth by Eustathius the Syrian. For the things which Euagrius says here were reported by Eustathius the Syrian are narrated by Nicephorus Callistus (XV 27). Furthermore, Priscus and Eustathius are cited so often by Nicephorus Callistus that you might rightly expect many fragments of Priscus or Eustathius to be contained in his ecclesiastical history. These are the things I thought should be said about Nicephorus Callistus, from which it appears why Procopius agrees so very often with Nicephorus.

We have seen that fragments of Priscus are found in the third book of the histories of Procopius; we understand that this writer of history wrote most diligently about the deeds of Attila from the fragments collected by C. Mueller (FHG IV p. 71 ff.). Procopius, however, narrates very few things about Attila and even hallucinates that Attila ravaged the whole of Europe after the death of Aëtius. Hence, I conclude that Procopius, when he was writing the first seven books on the wars, did not use Priscus, but that writer of history who himself had transcribed Priscus. It is likely that this was Eustathius, of whom Euagrius says (V 24): "Concerning the following times, it has been recorded by Zosimus up to Honorius and Arcadius... and whatever was collected after them by Priscus... all of which have been epitomized most excellently by Eustathius of Epiphaneia..."

Theophanes in many places deals with the same subject matter as Procopius in the proem of the third book on the wars. One must therefore ask whether Theophanes drew those things from Procopius or from the same source that Procopius had used. Indeed, Euagrius, when he reviews the histories of Procopius (IV 14 ff.), writes among other things: "To the same (Procopius), writing on the Vandals, the greatest things have been entrusted, and things worthy of a memory preserved forever, which I am about to relate. Huneric, having succeeded to the kingdom from Gaiseric, and practicing the Arian religion, acted most cruelly, etc." Euagrius, therefore, reviewing the books of Procopius on the Vandalic War, passes over all those things which were done before King Huneric and which were related by Procopius in the proem of the third book of his histories. However, the same things are found to a great extent also in the chronographia of Theophanes; cf.
