The slave system had spread to most industries and to every sort of work that could be done by gangs. Mines and metallurgical operations, the rowing of galleys, road-making and big building operations were all largely slave occupations. And almost all domestic service was performed by slaves. There were poor freemen men and there were reed-men in the cities and upon the country side, working for themselves or even working for wages. They were artizans, supervisors and so forth, workers of a new money-paid class working in competition with slave workers; but we do not know what proportion they made of the general population. It probably varied widely in different places and at different periods. And there were also many modifications of slavery, from the slavery that was chained at night and driven with whips to the farm or quarry, to the slave whose master found it advantageous to leave him to cultivate his patch or work his craft and own his wife like a free-man, provided he paid in a satisfactory quittance to his owner.
There were armed slaves. At the opening of the period of the Punic wars, in 264 B.C., the Etruscan sport of setting slaves to fight for their lives was revived in Rome. It grew rapidly fashionable; and soon every great Roman rich man kept a retinue of gladiators, who sometimes fought in the arena but whose real business it was to act as his bodyguard of bullies. And also there were learned slaves. The conquests of the later Republic were among the highly civilized cities of Greece, North Africa and Asia Minor; and they brought in many highly educated captives. The tutor of a young Roman of good family was usually a slave. A rich man would have a Greek slave as librarian, and slave secretaries and learned men. He would keep his poet as he would keep a performing dog. In this atmosphere of slavery the traditions of modern literary criticism were evolved. The slaves still boast and quarrel in our reviews. There were enterprising people who bought intelligent boy slaves and had them educated for sale. Slaves were trained as book copyists, as jewellers, and for endless skilled callings.
But there were very considerable changes in the position of a slave during the four hundred years between the opening days of conquest under the republic of rich men and the days of disintegration that followed the great pestilence. In the second century B.C. war-captives were abundant, manners gross and brutal; the slave had no rights and there was scarcely an outrage the reader can imagine that was not practised upon slaves in those days. But already in the first century A.D. there was a perceptible improvement in the attitude of the Roman civilization towards slavery. Captives were not so abundant for one thing, and slaves were dearer. And slave-owners began to realize that the profit and comfort they got from their slaves increased with the self-respect of these unfortunates. But also the moral tone of the community was rising, and a sense of justice was becoming effective. The higher mentality of Greece was qualifying the old Roman harshness. Restrictions upon cruelty were made, a master might no longer sell his slave to fight beasts, a slave was given property rights in what was called his peculium, slaves were paid wages as an encouragement and stimulus, a form of slave marriage was recognized. Very many forms of agriculture do not lend themselves to gang working, or require gang workers only at certain seasons. In regions where such conditions prevailed the slave presently became a serf, paying his owner part of his produce or working for him at certain seasons.
When we begin to realize how essentially this great Latin and Greek-speaking Roman Empire of the first two centuries A.D. was a slave state and how small was the minority who had any pride or freedom in their lives, we lay our hands on the clues to its decay and collapse. There was little of what we should call family life, few homes of temperate living and active thought and study; schools and colleges were few and far between. The free will and the free mind were nowhere to be found. The great roads, the ruins of splendid buildings, the tradition of law and power it left for the astonishment of succeeding generations must not conceal from us that all its outer splendour was built upon thwarted wills, stifled intelligence, and crippled and perverted desires. And even the minority who lorded it over that wide realm of subjugation and of restraint and forced labour were uneasy and unhappy in their souls; art and literature, science and philosophy, which are the fruits of free and happy minds, waned in that atmosphere. There was much copying and imitation, an abundance of artistic artificers, much slavish pedantry among the servile men of learning, but the whole Roman empire in four centuries produced nothing to set beside the bold and noble intellectual activities of the comparatively little city of Athens during its one century of greatness. Athens decayed under the Roman sceptre. The science of Alexandria decayed. The spirit of man, it seemed, was decaying in those days.
