Zosimus, New History 1.32
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.
[1.32.1] While the Scythians plundered all before them, the people who inhabited on the sea-coast of Pontus, removed into the fortified towns in the interior; the barbarians at the same time making an attack on Pityus, which is surrounded by a strong wall, and possesses a convenient harbor. But Successianus, who commanded the army there, made so vigorous a defence, that the barbarians were routed, and in such dread lest the other garrisons hearing what was done might join with that of Pityus and totally destroy them, that they hastened with the utmost speed to their ships, and returned home under great hazard, having lost many of their companions at the battle of Pityus.
[1.32.2] Thus the inhabitants of the vicinity of the Euxine Sea, who owed their preservation to the conduct of Successianus, were relieved from all present apprehension lest the Scythians after this repulse should pay them another visit. But while Valerian sent for Successianus, made him prefect of the court, and consulted with him about the repairing of Antioch, the Scythians procured ships from the Bosphorans, and again crossed the streight.
[1.32.3] The inhabitants of the other side retained the vessels, and would not permit the Bosphorans to take them home again, as they had before done, on which they advanced into the country near to Phasis, where is the temple of Diana, called from the place Phasiana, and the palace of king Aeeta; and having made a fruitless attempt to take that temple, proceeded direct to Pityus.
