depravation of manners, are commonly expressive of their peculiar temper and situation. There are few observers, who possess a clear and comprehensive view of the revolutions of society; and who are capable of discovering the nice and secret springs of action, which impel, in the same uniform direction, the blind and capricious passions of a multitude of individuals. If it can be affirmed, with any degree of truth, that the luxury of the Romans was more shameless and dissolute in the reign of Theodosius than in the age of Constantine, perhaps, or of Augustus, the alteration cannot be ascribed to any beneficial improvements, which had gradually increased the stock of national riches. A long period of calamity or decay must have checked the industry, and diminished the wealth, of the people; and their profuse luxury must have been the result of that indolent despair, which enjoys the present hour, and declines the thoughts of futurity. The uncertain condition of their property discouraged the subjects of Theodosius from engaging in those useful and laborious undertakings which require an immediate expense, and promise a slow and distant advantage. The frequent examples of ruin and desolation tempted them not to spare the remains of a patrimony, which might, every hour, become the prey of the rapacious Goth. And the mad prodigality which prevails in the confusion of a shipwreck, or a siege, may serve to explain the progress of luxury amidst the misfortunes and terrors of a sinking nation.

The effeminate luxury, which infected the manners of courts and cities, had instilled a secret and destructive poison into the camps of the legions; and their degeneracy has been marked by the pen of a military writer, who had accurately studied the genuine and ancient principles of Roman discipline. It is the just and important observation of Vegetius, that the infantry was invariably covered with defensive armor, from the foundation of the city, to the reign of the emperor Gratian. The relaxation of discipline, and the disuse of exercise, rendered the soldiers less able, and less willing, to support the fatigues of the service; they complained of the weight of the armor, which they seldom wore; and they successively obtained the permission of laying aside both their cuirasses and their helmets. The heavy weapons of their ancestors, the short sword, and the formidable pilum, which had subdued the world, insensibly dropped from their feeble hands. As the use of the shield is incompatible with that of the bow, they reluctantly marched into the field; condemned to suffer either the pain of wounds, or the ignominy of flight, and always disposed to prefer the more shameful alternative. The cavalry of the Goths, the Huns, and the Alani, had felt the benefits, and adopted the use, of defensive armor; and, as they excelled in the management of missile weapons, they easily overwhelmed the naked and trembling legions, whose heads and breasts were exposed, without defence, to the arrows of the Barbarians. The loss of armies, the destruction of cities, and the dishonor of the Roman name, ineffectually solicited the successors of Gratian to restore the helmets and the cuirasses of the infantry. The enervated soldiers abandoned their own and the public defence; and their pusillanimous indolence may be considered as the immediate cause of the downfall of the empire.
