Zosimus, New History 4.06
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.
[4.6.1] But the city being in general confusion, and no person being sufficiently collected in mind by reason of the surprise to know how to act, Procopius imagined his design to be still undiscovered, and that he might secure the empire if the enterprise were no further revealed.
[4.6.2] Having then seized on Caesarius, whom the emperors had made prefect of the city, and on Nebridius, who was appointed to succeed Sallustius in the prefecture of the court, he compelled them to write to the subjects of the empire whatever he wished. He also kept them separate, that they might not consult with each other.
[4.6.3] Having formed these projects, he proceeded in a splendid manner towards the palace. Ascending a tribunal before the gate, he gave the people great hopes and promises. He then entered the palace to provide for the remainder of his affairs. The new emperors having divided the army between them, Procopius determined to send persons to the soldiers, who were as yet in confusion, and went by the command of the emperors from place to place without any order. He thus hoped to seduce some of them to his party.
[4.6.4] Nor did he fail of accomplishing his purpose with ease by distributing money amongst the soldiers and their officers; by which means he collected a considerable force, and prepared to make an open attack on the enemy. Procopius then sent Marcellus into Bithynia with an army against Serenianus and the imperial cavalry that was under his command, in hope of cutting them to pieces.
[4.6.5] This force having fled to Cyzicus, Marcellus, whose army was superior to theirs both by sea and land, took possession of that town, and having taken Serenianus, who fled into Lydia, put him to death.
