The Roman of those centuries had little need of medicine, for his active life in farming or soldiering kept him healthy and strong. He took to the land as the Greek to the sea; he based his life on the soil, built his towns as meeting places for farmers and their products, organized his armies and his state on his readiness to defend and extend his holdings, and conceived his gods as spirits of the living earth and the nourishing sky.
As far back as we can reach into Rome’s past we find private property.50 Part of the land, however, was ager publicus—public acreage usually acquired by conquest and owned by the state. The peasant family of the early Republic owned two or three acres, tilled them with all hands and occasionally a slave, and lived abstemiously on the product. They slept on straw,51 rose early, stripped to the waist,52 and plowed and harrowed behind leisurely oxen whose droppings served as fertilizer, and their flesh as a religious offering and a festival food. Human offal was also used to enrich the soil, but chemical fertilizers were rare in Italy before the Empire. Manuals of scientific agriculture were imported from Carthage and Greece. Crops were rotated between grains and legumes, and lands were turned periodically to pasturage to prevent their exhaustion. Vegetables and fruits were grown in abundance, and formed, next to grains, the chief articles of food. Garlic was already a favorite seasoning. Some aristocratic families derived their names in part from the vegetables traditionally favored in their plantings: Lentuli, Caepiones, Fabii, from lentils, onions, beans. Culture of the fig, olive, and grape gradually encroached upon cereal and vegetable crops. Olive oil took the place of butter in the diet and of soap in the bath; it served as fuel in torches and lamps and was the chief ingredient in the unguents made necessary for hair and skin by the dry winds and fiery sun of the Mediterranean summer. Sheep were the favorite herd, for the Italians preferred clothing of wool. Swine and poultry were raised in the farmyard, and almost every family nursed a garden of flowers.54
War transformed this picture of rural toil. Many of the farmers who changed plowshares for swords were overcome by the enemy or the town and never returned to their fields; many others found their holdings so damaged by armies or neglect that they had not the courage to begin anew; others were broken by accumulated debt. Such men sold their lands at depression prices to aristocrats or agricultural capitalists who merged the little homesteads into latifundia (literally, broad farms), turned these vast areas from cereals to flocks and herds, orchards and vines, and manned them with war-captured slaves under an overseer who was often himself a slave. The owners rode in now and then to look at their property; they no longer put their hands to the work, but lived as absentee landlords in their suburban villas or in Rome. This process, already under way in the fourth century B.C., had by the end of the third produced a debt-ridden tenant class in the countryside, and in the capital a propertyless, rootless proletariat whose sullen discontent would destroy the Republic that peasant toil had made.
