Lactantius

“ The distinguished comeliness of his figure, his strict attention to all military duties, his virtuous demeanour and singular affability, had endeared him to the troops, and made him the choice of every individual. ”

“ That the case of Nerva was very different: he, after having reigned a single year, felt himself, either from age or from inexperience in business, unequal to affairs so momentous, and therefore threw aside the helm of government, and returned to that private life in which he had already grown old. But Diocletian added, that if Galerius wished for the title of emperor, there was nothing to hinder its being conferred on him and Constantius, as well as on Maximian Herculius. ”
