At the same time when Decius was struggling with the violence of the tempest, his mind, calm and deliberate amidst the tumult of war, investigated the more general causes that, since the age of the Antonines, had so impetuously urged the decline of the Roman greatness. He soon discovered that it was impossible to replace that greatness on a permanent basis without restoring public virtue, ancient principles and manners, and the oppressed majesty of the laws. To execute this noble but arduous design, he first resolved to revive the obsolete office of censor; an office which, as long as it had subsisted in its pristine integrity, had so much contributed to the perpetuity of the state, till it was usurped and gradually neglected by the Cæsars. Conscious that the favor of the sovereign may confer power, but that the esteem of the people can alone bestow authority, he submitted the choice of the censor to the unbiased voice of the senate. By their unanimous votes, or rather acclamations, Valerian, who was afterwards emperor, and who then served with distinction in the army of Decius, was declared the most worthy of that exalted honor. As soon as the decree of the senate was transmitted to the emperor, he assembled a great council in his camp, and before the investiture of the censor elect, he apprised him of the difficulty and importance of his great office. “Happy Valerian,” said the prince to his distinguished subject, “happy in the general approbation of the senate and of the Roman republic! Accept the censorship of mankind; and judge of our manners. You will select those who deserve to continue members of the senate; you will restore the equestrian order to its ancient splendor; you will improve the revenue, yet moderate the public burdens. You will distinguish into regular classes the various and infinite multitude of citizens, and accurately view the military strength, the wealth, the virtue, and the resources of Rome. Your decisions shall obtain the force of laws. The army, the palace, the ministers of justice, and the great officers of the empire, are all subject to your tribunal. None are exempted, excepting only the ordinary consuls, the præfect of the city, the king of the sacrifices, and (as long as she preserves her chastity inviolate) the eldest of the vestal virgins. Even these few, who may not dread the severity, will anxiously solicit the esteem, of the Roman censor.”
