During the sixty years which elapse from the death of S. John to the accession of Marcus, the Roman empire is ruled by three sovereigns, who have each left a fair name and a considerable renown behind them, and who, compared with most of those who preceded or who followed them, may almost be termed great. Trajan by his military successes raised to the highest point the credit of the Roman arms, by his moderation in civil government effaced the remembrance of Domitian’s cruelties, and gave the Romans perhaps as much liberty as they could bear. His successor Hadrian, joining great energy, administrative ability, and moderation of his own to the fear and respect for the Roman name, which the powerful arm of Trajan had spread around, was able at once to exercise his army with unwearied discipline, and to maintain the empire at its full tide of power in honourable peace, while Antoninus crowned the forty years of equable and generally just government—bestowed on the Roman world by Trajan and Hadrian—with a further happy period of more than half that length, wherein the glory of the empire may be said to have culminated. Imperial Rome never saw again such a day of power, or such a prospect of security, as when Antoninus celebrated the secular games at the completion of nine hundred years; and for ages afterwards his name carried respect, and men looked back on his reign as on an ideal period of happiness for those whom he ruled. One of the most competent observers of our time has marked the last ten years of the reign of Pius as the period at which the independent development of Græco-Roman heathenism terminated, when it had exhausted all the forms of its own inward life, since the Neoplatonic philosophy which is the only striking product of intelligence that arises afterwards, is manifestly due to the antagonism with Christianity, and is no pure offspring of the heathen spirit.(149) From this time forth Christian influences become unmistakable in their action upon heathen thought and society. This, then, affords another reason why we should endeavour to trace the progress and extension which the Church had reached at this point.
