It is true, most true, that slavery stands on force and not on right. It is a hideous result of war, or of that barbarism in which savage war plays its conspicuous part. To the victor belonged the lives of his captives, and, by consequence, he might bind them in perpetual servitude. This principle, which has been the foundation of slavery in all ages, is adapted only to the rudest conditions of society, and is wholly inconsistent with a period of refinement, humanity, and justice. It is sad to confess that it was recognized by Greece; but the civilization of this famed land, though brilliant to the external view as the immortal sculptures of the Parthenon, was, like that stately temple, dark and cheerless within.
Slavery extended, with new rigors, under the military dominion of Rome. The spirit of freedom which animated the Republic was of that selfish and intolerant character which accumulated privileges upon the Roman citizen, while it heeded little the rights of others. But, unlike the Greeks, the Romans admitted in theory that all men are originally free by the Law of Nature; and they ascribed the power of masters over slaves, not to any alleged diversities in the races of men, but to the will of society.[16] The constant triumphs of their arms were signalized by reducing to servitude large bodies of subjugated people. Paulus Æmilius returned from Macedonia with an uncounted train of slaves, composed of persons in every sphere of life; and the camp of Lucullus in Pontus witnessed the sale of slaves for four drachmæ, or seventy-five cents, a head.
Terence and Phædrus, Roman slaves, teach us that genius is not always quenched even by degrading bondage; while the writings of Cato the Censor, one of the most virtuous slave-masters in history, show the hardening influence of a system which treats human beings as cattle. "Let the husbandman," says Cato, "sell his old oxen, his sickly cattle, his sickly sheep, his wool, his hides, his old wagon, his old implements, his old slave, and his diseased slave; and if there is anything else not wanted, let him sell it. He should be seller, rather than buyer."[17]
The cruelty and inhumanity which flourished in the Republic professing freedom enjoyed a natural home under Emperors who were the high-priests of despotism. Wealth increased, and with it the multitude of slaves. Some masters are said to have owned as many as ten thousand, while extravagant prices were often paid for them, according to fancy or caprice. Martial mentions handsome boys sold for as much as two hundred thousand sesterces each, or more than eight thousand dollars.[18] On the assassination of Pedanius Secundus by one of his slaves, no less than four hundred were put to death,—an orator in the Senate arguing that these hecatombs were in accordance with ancient custom.[19]
It is easy to believe that slavery, which prevailed so largely in Greece and Rome, must have existed in Africa. Here, indeed, it found a peculiar home. If we trace the progress of this unfortunate continent from those distant days of fable when Jupiter did not
"disdain to grace
The feasts of Æthiopia's blameless race,"[20]
the merchandise in slaves will be found to have contributed to the abolition of two hateful customs, once universal in Africa,—the eating of captives, and their sacrifice to idols. Thus, in the march of civilization, even the barbarism of slavery is an important stage of Human Progress. It is a point in the ascending scale from cannibalism.
