Zosimus, New History 1.26
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.
[1.26.1] Gallus was so supine in the administration of the empire, that the Scythians in the first place terrified all the neighboring nations, and then laid waste all the countries as far by degrees as the sea coast; not leaving one nation subject to the Romans unpillaged, and taking almost all the unfortified towns, and many that were fortified.
[1.26.2] Besides the war on every side, which was insupportably burdensome to them, the cities and villages were infested with a pestilence, which swept away the remainder of mankind in those regions; nor was so great a mortality ever known in any former period.
