Zosimus, New History 1.41
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.
 When the troops were calmed by their commanders, Claudius was chosen emperor, having previously been designed for that dignity by general consent. Aureolus, who had for a long time kept himself out of the hands of Gallienus, presently sent agents to Claudius, to effect a peace. Surrendering himself, he was killed by the guards of the emperor, who still remembered the hatred they bore against him for his treachery.
