Tillemont (_Histoire des Empereurs,_ &c., t. ii. p. 59), with so much justice and precision that it is a pleasure to quote his own words. “Seeing,” says he, “that his age was despised, and that the empire required some one who combined strength of mind and body, Nerva, being free from that blindness which prevents one from discussing and measuring one’s own powers, and from that thirst for dominion which often prevails over even those who are nearest to the grave, resolved to take a partner in the sovereign power, and showed his wisdom by making choice of Trajan.” By this choice, indeed, Nerva commenced and inaugurated the finest period of the Roman empire, the period that contemporaries entitled the golden age, and that history has named the age of the Antonines. It is desirable to become acquainted with the real character of this period, for to it belong the two greatest historical events--the dissolution of ancient pagan, and the birth of modern Christian society. Five notable sovereigns, Nerva, Trajan, Hadrian, Antoninus Pius, and Marcus Aurelius swayed the Roman empire during this period (A.D. 96-150). What Nerva was has just been described; and he made no mistake in adopting Trajan as his successor. Trajan, unconnected by origin, as Nerva also had been, with old Rome, was born in Spain, near Seville, and by military service in the East had made his first steps towards fortune and renown. He was essentially a soldier--a moral and a modest soldier; a friend to justice and the public weal; grand in what he undertook for the empire he governed; simple and modest on his own score; respectful towards the civil authority and the laws; untiring and equitable in the work of provincial administration; without any philosophical system or pretensions; full of energy and boldness, honesty and good sense. He stoutly defended the empire against the Germans on the banks of the Danube, won for it the province of Dacia, and, being more taken up with the East than the West, made many Asiatic conquests, of which his successor, Hadrian, lost no time in abandoning, wisely no doubt, a portion. Hadrian, adopted by Trajan, and a Spaniard too, was intellectually superior and morally very inferior to him. He was full of ambition, vanity, invention, and restlessness; he was sceptical in thought and cynical in manners; and he was overflowing with political, philosophical, and literary views and pretensions. He passed the twenty-one years of his reign chiefly in travelling about the empire, in Asia, Africa, Greece, Spain, Gaul, and Great Britain, opening roads, raising ramparts and monuments, founding schools of learning and museums, and encouraging among the provinces, as well as at Rome, the march of administration, legislation, and intellect, more for his own pleasure and his own glorification than in the interest of his country and of society. At the close of this active career, when he was ill and felt that he was dying, he did the best deed of his life.
