"The first exploits of Trajan were against the Dacians, the most warlike of men, who dwelt beyond the Danube, and who, during the reign of Domitian, had insulted with impunity, the majesty of Rome. To the strength and fierceness of barbarians they added a contempt for life, which was derived from a warm persuasion of the immortality and transmigration of the soul. Decebalus, the Dacian king, approved himself a rival not unworthy of Trajan; nor did he despair of his own and the public fortune, till, by the confession of his enemies, he had exhausted every resource both of valour and policy. This memorable war, with a very short suspension of hostilities, lasted five years; and as the emperor could exert, without control, the whole force of the state, it was terminated by the absolute submission of the barbarians."
"The various modes of worship which prevailed in the Roman world were all considered by the people as equally true; by the philosopher as equally false; and by the magistrate as equally useful. And thus toleration produced not only mutual indulgence, but even religious concord."
"So sensible were the Romans of the influence of language over national manners, that it was their most serious care, to extend with the progress of their arms, the use of the Latin tongue. The ancient dialects of Italy, the Sabine, the Etruscan, and the Venetian, sunk into oblivion; but in the provinces, the east was less docile than the west to the voice of its victorious preceptors. The obvious difference marked the two portions of the empire with a distinction of colours, which, though it was to some degree concealed during the meridian splendour of prosperity, became gradually more visible as the shades of night descended upon the Roman world."
