Zosimus, New History 5.49
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.
[5.49.1] When the emperor received this letter, he condemned Jovius for his forward temerity, and wrote to him, telling him, that it was proper for him, as prefect of the court, and understanding what the public revenues were capable of, to assign the quantity of corn and gold, but that no dignity or command should ever be conferred on Alaric or any of his family.
[5.49.2] When Jovius received this letter, he opened and read it in the hearing of Alaric who, though he bore all the rest with patience, yet on finding the command denied to himself and all his family, was so enraged, that he immediately commanded his barbarians to march to Rome with the greatest expedition, and there revenge the affront offered to him and all his family. Jovius being disappointed on seeing the emperor's unexpected letter, returned to Ravenna. Being desirous to acquit himself of all blame, he bound Honorius under several oaths never to make peace with Alaric, but to wage against him a continual war, which be himself likewise swore by touching the head of the emperor, and caused all others who were in office to do the same.
