Lactantius

“ Constantine stood near in public view, and men began to question amongst themselves whether his name too had not been changed into Maximin; when, in the sight of all, Galerius, stretching back his hand, put Constantine aside, and drew Daia forward, and, having divested him of the garb of a private person, set him in the most conspicuous place. All men wondered who he could be, and from whence he came ”

“ Diocletian, with tears, harangued them, and said that he was become infirm, that he needed repose after his fatigues, and that he would resign the empire into hands more vigorous and able, and at the same time appoint new Cæsars. The spectators, with the utmost earnestness, waited for the nomination. Suddenly he declared that the Cæsars were Severus and Maximin. The amazement was universal. ”
