Tacitus, The Annals — Book 1 (1876)
“ Am I to call you soldiers, you who have beset with entrenchments and arms your general's son, or citizens, when you have trampled under foot the authority of the Senate? Even the rights of public enemies, the sacred character of the ambassador, and the law of nations have been violated by you. The Divine Julius once quelled an army's mutiny with a single word by calling those who were renouncing their military obedience 'citizens.' The Divine Augustus cowed the legions who had fought at Actium with one look of his face. ”
