Zosimus, New History 1.25
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.
[1.25.1] Gallus, having made these regulations, came to Rome, priding himself on the peace he had made with the barbarians. And though he at first spoke with approbation of Decius's mode of government, and adopted one of his sons,
[1.25.2] yet, after some time was elapsed, fearing that some of them who were fond of new projects might recur to a recapitulation of the princely virtues ot' Decius, and therefore might at some opportunity give the empire to his son, he concerted the young man's destruction, without regard either to his own adoption of him, or to common honor and justice.
