Zosimus, New History 3.35

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.

[3.35.1] Jovian now turning his attention to the affairs of government, made various arrangements, and sent Lucilianus his father-in-law, Procopius, and Valentinian, who was afterwards emperor, to the armies in Pannonia, to inform them of the death of Julian, and of his being chosen emperor. 

[3.35.2] The Batavians who were at Sirmium, and were left there for its protection, as soon as they received the news, put to death Lucilianus who brought such unwelcome intelligence, without regard to his relationship to the emperor. Such was the respect they had to Jovian's relations, that Valentinian himself only escaped from the death they intended to inflict on him. 

[3.35.3] Jovianus proceeding from Antioch towards Constantinople, suddenly fell sick at Dadastana in Bithynia, and died after a reign of eight months, in which short time he had not been able to render the public any essential service.
