And nothing, in my opinion, after these details, need stand in the way of stating the periods of the Roman emperors, in order to the demonstration of the Saviour’s birth. Augustus, forty-three years; Tiberius, twenty-two years; Caius, four years; Claudius, fourteen years; Nero, fourteen years; Galba, one year; Vespasian, ten years; Titus, three years; Domitian, fifteen years; Nerva, one year; Trajan, nineteen years; Adrian, twenty-one years; Antoninus, twenty-one years; likewise again, Antoninus and Commodus, thirty-two. In all, from Augustus to Commodus, are two hundred and twenty-two years; and from Adam to the death of Commodus, five thousand seven hundred and eighty-four years, two months, twelve days.
