Zosimus, New History 5.27

Zosimus (Greek Ζώσιμος): Early Byzantine, pagan author of a history of the Roman Empire, published in the first quarter of the sixth century CE.

The translation of ZosimusNew History offered here was printed in 1814 by W. Green and T. Chaplin in London, and was probably prepared by J. Davis of the Military Chronicle and Military Classics Office. The translator is anonymous. The text was found at Tertullian.org. The notes were added by Jona Lendering.

[5.27.1] He arrived at Ravenna, an ancient city, which is the metropolis of the province of Flaminia, and a Thessalian colony. It is called Rhene, because it is surrounded by water (as the word Rhene imports), and not so named, as Olympiodorus of Thebes relates, from Remus, the brother of Romulus, who founded it;

[5.27.2] for he must yield in this to Quadratus, who has mentioned this very circumstance in his history of the emperor Marcus. At Ravenna, Stilicho being intent on his preparations for attacking the Illyrian towns, and by the aid of Alaric expecting to separate them from Arcadius, and to unite them to the empire of Honorius, two impediments at the same time happened to fall in his way. These were a report that Alaric was dead, and letters from the emperor Honorius at Rome, informing him that Constantine had revolted, and had advanced from the island of Britain into the Transalpine provinces, where he conducted himself in the cities as emperor. 

[5.27.3] The rumor concerning the death of Alaric appeared doubtful, before some persons arrived and assured him of the reality of it. But the report that Constantine had set up for the empire was universally believed. Stilicho, being thus prevented from executing his intended expedition against the Illyrians, proceeded to Rome to consult with other persons concerning the present state of affairs.
