The science, art, and political condition of nations are often illustrated by their coinage. An interesting view of the progress of Europe might be obtained from a philosophical study of its numismatic remains. The simplicity of the earlier ages is indicated by the pure silver, such as that coined at Crotona, B.C. 600--that of the reign of Philip of Macedon by the native unalloyed gold. A gradual decline in Roman prosperity is more than shadowed forth by the gradual deterioration of its money; for, as evil times befell the state, the emperors were compelled to utter a false coinage. Thus, under Vespasian, A.D. 69, the silver money contained about one fourth of its weight of copper; under Antoninus Pius, A.D. 138, more than one third; under Commodus, A.D. 180, nearly one half; under Gordian, A.D. 236, there was added to the silver more than twice its weight of copper. Nay, under Gallienus, a coinage was issued of copper, tin and silver, in which the first two metals exceed the last by more than two hundred times its weight. It shows to what a hopeless condition the state had come. The Roman demagogues, as is the instinct of their kind, made political capital by attacking industrial capital. They lowered the rate of interest, prohibited interest, and often attempted the abolition of debts. [Sidenote: Indescribable depravity in the Roman decline.] [Sidenote: Dissoluteness of the women, and avoidance of marriage.] The concentration of power and increase of immorality proceeded with an equal step. In its earlier ages, the Roman dominion was exercised by a few thousand persons; then it passed into the hands of some score families; then it was sustained for a moment by individuals, and at last was seized by one man, who became the master of 120 millions. As the process went on, the virtues which had adorned the earlier times disappeared, and in the end were replaced by crimes such as the world had never before witnessed and never will again. An evil day is approaching when it becomes recognized in a community that the only standard of social distinction is wealth. That day was soon followed in Rome by its unavoidable consequence, a government founded upon two domestic elements, corruption and terrorism. No language can describe the state of that capital after the civil wars. The accumulation of power and wealth gave rise to a universal depravity. Law ceased to be of any value. A suitor must deposit a bribe before a trial could be had. The social fabric was a festering mass of rottenness. The people had become a populace; the aristocracy was demoniac; the city was a hell. No crime that the annals of human wickedness can show was left unperpetrated--remorseless murders; the betrayal of parents, husbands, wives, friends; poisoning reduced to a system; adultery degenerating into incests, and crimes that cannot be written. Women of the higher class were so lascivious, depraved, and dangerous, that men could not be
