The private life of the Greeks and Romans, as described in the preceding pages, would have been impossible without the existence of a large servile class. Slaves did much of the heavy and disagreeable work in the ancient world, thus allowing the free citizen to engage in more honorable employment or to pass his days in dignified leisure. SOURCES OF SLAVES The Greeks seem sometimes to have thought that only barbarians should be degraded to the condition of servitude. Most Greek slaves, as a matter of fact, were purchased from foreign countries. But after the Romans had subdued the Mediterranean world, their captives included not only members of inferior races, but also the cultivated inhabitants of Greece, Egypt, and Asia Minor. We hear of slaves at Rome who served as clerks, secretaries, librarians, actors, and musicians. Their education was often superior to that of the coarse and brutal masters who owned them. NUMBER AND CHEAPNESS OF SLAVES The number of slaves, though great enough in Athens and other Greek cities, reached almost incredible figures during the later period of Roman history. Every victorious battle swelled the troops of captives sent to the slave markets at Rome. Ordinary slaves became as cheap as beasts of burden are now. The Roman poet Horace tells us that at least ten slaves were necessary for a gentleman in even moderate circumstances. Wealthy individuals, given to excessive luxury, might number their city slaves by the hundreds, besides many more on their country estates. SLAVES' TASKS Slaves engaged in a great variety of occupations. They were domestic servants, farm laborers, miners, artisans, factory hands, and even shopkeepers. Household slaves at Rome were employed in every conceivable way. Each part of a rich man's residence had its special staff of servants. The possession of a fine troop of slaves, dressed in handsome liveries, was a favorite method of showing one's wealth and luxury. TREATMENT OF SLAVES It is difficult for us to realize the attitude of ancient peoples toward their slaves. They were regarded as part of the chattels of the house--as on a level with domestic animals rather than human beings. Though Athenian law forbade owners to kill their slaves or to treat them cruelly, it permitted the corporal punishment of slaves for slight offenses. At Rome, until the imperial epoch, [19] no restraints whatever existed upon the master's power. A slave was part of his property with which he could do exactly as he pleased. The terrible punishments, the beating with scourges which followed the slightest misconduct or neglect of duty, the branding with a hot iron which a runaway slave received, the fearful penalty of crucifixion which followed an attempt upon the owner's life--all these tortures show how hard was the lot of the bondman in pagan Rome.
