Zosimus, New History 2.47
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.
[2.47.1] This speech of Philip nearly occasioned a mutiny of the whole army. Magnentius, therefore being alarmed, with much difficulty prevailed on the soldiers to attend to him. He said that he likewise was desirous of concluding a peace, but would then dismiss the assembly, until he had deliberated how to act.
[2.47.2] Upon which, the assembly being dissolved, Marcellianus entertained Philip as one whom he was desirous of obliging by the laws of hospitality. Meanwhile, Magnentius debated with himself, whether to dismiss Philip without the purpose of his embassy being effected or, in violation of the law of nations, detain him.
[2.47.3] He determined, after much hesitation, to invite all the officers of his army to sup with him, and at table inform them of his opinion. The following day he again convened the army; he reminded them of the injuries they received from Constans when furious and intoxicated. That the soldiers could not sustain the enormities with which he oppressed the state contrary to all law and justice, but had inclined to what was most for the public advantage; and that after they had freed the cities from so savage a monster, they had compelled him to become their emperor.
