Zosimus, New History 4.04

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 Zosimus' New 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.

[4.4.1] while Valens was surrounded with disquietude on every side, having always lived inactively, and having been raised to the empire suddenly. He could not indeed sustain the weight of business. He was disturbed, not by the Persians only, who were elated with their prosperity, which had increased since their truce with Jovian. They made incursions on the provinces without controul, since Nisibis was in their possession, and by distressing the eastern towns, constrained the emperor to march against them.

[4.4.2] On his departure from Constantinople, the rebellion of Procopius commenced. This person had been entrusted by Julian, being one of his relations, with a part of his forces, and had been charged to march with Sebastianus through Adiabene, and to meet Julian, who took another route. Permission, moreover, was given him to wear a purple robe, for a reason which no other person was acquainted with. 

[4.4.3] But the deity being pleased to ordain it otherwise, and Jovian having succeeded to the imperial dignity, Procopius immediately delivered up the imperial robe which he had received from Julian, confessing why it had been given to him, and intreating the emperor to absolve him from his military oath, and to allow him to live in retirement, and to attend to agriculture and his own private affairs. Having obtained this, he went with his wife and children to Caesarea in Cappadocia, intending to reside in that place, where he possessed a valuable estate.
